These numbers are for 32 iterations ("$2a$05"):

(*) built with -fomit-frame-pointer -funroll-loops, which I don't
think happens for libcrypt.
Starting with version 1.1 released in June 2011, default builds of
crypt_blowfish invoke a quick self-test on every hash computation.
This has roughly a 4.8% performance impact at "$2a$05", but only a 0.6%
impact at a more typical setting of "$2a$08".
The large speedup for the original Pentium is due to the assembly
code and the weird optimizations this processor requires.
The numbers for password cracking are 2 to 10% higher than those for
crypt_blowfish as certain things may be done out of the loop and the
code doesn't need to be reentrant.
Recent versions of John the Ripper (1.6.25-dev and newer) achieve an
additional 15% speedup on the Pentium Pro family of processors (which
includes Pentium III) with a separate version of the assembly code and
run-time CPU detection.

This is an implementation of a password hashing method, provided via the
crypt(3) and a reentrant interface. It is fully compatible with
OpenBSD's bcrypt.c for prefix "$2b$", originally by Niels Provos and
David Mazieres. (Please refer to the included crypt(3) man page for
information on minor compatibility issues for other bcrypt prefixes.)
I've placed this code in the public domain, with fallback to a
permissive license. Please see the comment in crypt_blowfish.c for
more information.
You can use the provided routines in your own packages, or link them
into a C library. I've provided hooks for linking into GNU libc, but
it shouldn't be too hard to get this into another C library. Note
that simply adding this code into your libc is probably not enough to
make your system use the new password hashing algorithm. Changes to
passwd(1), PAM modules, or whatever else your system uses will likely
be needed as well. These are not a part of this package, but see
LINKS for a pointer to our tcb suite.
Instructions on using the routines in one of the two common ways are
given below. It is recommended that you test the routines on your
system before you start. Type "make check" or "make check_threads"
(if you have the POSIX threads library), then "make clean".
1. Using the routines in your programs.
The available interfaces are in ow-crypt.h, and this is the file you
should include. You won't need crypt.h. When linking, add all of the
C files and x86.S (you can compile and link it even on a non-x86, it
will produce no code in this case).
2. Building the routines into GNU C library.
For versions 2.13 and 2.14 (and likely other nearby ones), extract the
library sources as usual. Apply the patch for glibc 2.14 provided in
this package. Enter crypt/ and rename crypt.h to gnu-crypt.h within
that directory. Copy the C sources, header, and assembly (x86.S) files
from this package in there as well (but be sure you don't overwrite the
Makefile). Configure, build, and install the library as usual.
For versions 2.2 to 2.3.6 (and likely also for some newer ones),
extract the library sources and maybe its optional add-ons as usual.
Apply the patch for glibc 2.3.6 provided in this package. Enter
crypt/ and rename crypt.h to gnu-crypt.h within that directory. Copy
the C sources, header, and assembly (x86.S) files from this package in
there as well (but be sure you don't overwrite the Makefile).
Configure, build, and install the library as usual.
For versions 2.1 to 2.1.3, extract the library sources and the crypt
and linuxthreads add-ons as usual. Apply the patch for glibc 2.1.3
provided in this package. Enter crypt/sysdeps/unix/, and rename
crypt.h to gnu-crypt.h within that directory. Copy C sources, header,
and assembly (x86.S) files from this package in there as well (but be
sure you don't overwrite the Makefile). Configure, build, and install
the library as usual.
Programs that want to use the provided interfaces will need to include
crypt.h (but not ow-crypt.h directly). By default, prototypes for the
new routines aren't defined (but the extra functionality of crypt(3)
is indeed available). You need to define _OW_SOURCE to obtain the new
routines as well.

.SH DESCRIPTION
The
.crypt and
functions calculate a cryptographic hash function of
.I key
with one of a number of supported methods as requested with
.IR setting ,
which is also used to pass a salt and possibly other parameters to
the chosen method.
The hashing methods are explained below.
.PP
Unlike
.BR crypt ,
the functions
.BR crypt_r ,
.BR crypt_rn " and"
.B crypt_ra
are reentrant.
They place their result and possibly their private data in a
.I data
area of
.I size
bytes as passed to them by an application and/or in memory they
allocate dynamically. Some hashing algorithms may use the data area to
cache precomputed intermediate values across calls. Thus, applications
must properly initialize the data area before its first use.
.B crypt_r
requires that only
.I data->initialized
be reset to zero;
.BR crypt_rn " and " crypt_ra
require that either the entire data area is zeroed or, in the case of
.BR crypt_ra ,
.I *data
is NULL. When called with a NULL
.I *data
or insufficient
.I *size
for the requested hashing algorithm,
.B crypt_ra
uses
.BR realloc (3)
to allocate the required amount of memory dynamically. Thus,
.B crypt_ra
has the additional requirement that
.IR *data ,
when non-NULL, must point to an area allocated either with a previous
call to
.B crypt_ra
or with a
.BR malloc (3)
family call.
The memory allocated by
.B crypt_ra
should be freed with
.BR free "(3)."
.PP
The
.crypt_gensalt and
functions compile a string for use as
.I setting
\- with the given
.I prefix
(used to choose a hashing method), the iteration
.I count
(if supported by the chosen method) and up to
.I size
cryptographically random
.I input
bytes for use as the actual salt.
If
.I count
is 0, a low default will be picked.
The random bytes may be obtained from
.BR /dev/urandom .
Unlike
.BR crypt_gensalt ,
the functions
.BR crypt_gensalt_rn " and " crypt_gensalt_ra
are reentrant.
.B crypt_gensalt_rn
places its result in the
.I output
buffer of
.I output_size
bytes.
.B crypt_gensalt_ra
allocates memory for its result dynamically. The memory should be
freed with
.BR free "(3)."
.SH RETURN VALUE
Upon successful completion, the functions
.crypt and
return a pointer to a string containing the setting that was actually used
and a printable encoding of the hash function value.
The entire string is directly usable as
.I setting
with other calls to
.crypt and
and as
.I prefix
with calls to
.crypt_gensalt and .
.PP
The behavior of
.B crypt
on errors isn't well standardized. Some implementations simply can't fail
(unless the process dies, in which case they obviously can't return),
others return NULL or a fixed string. Most implementations don't set
.IR errno ,
but some do. SUSv2 specifies only returning NULL and setting
.I errno
as a valid behavior, and defines only one possible error
.RB "(" ENOSYS ,
"The functionality is not supported on this implementation.")
Unfortunately, most existing applications aren't prepared to handle
NULL returns from
.BR crypt .
The description below corresponds to this implementation of
.BR crypt " and " crypt_r
only, and to
.BR crypt_rn " and " crypt_ra .
The behavior may change to match standards, other implementations or
existing applications.
.PP
.BR crypt " and " crypt_r
may only fail (and return) when passed an invalid or unsupported
.IR setting ,
in which case they return a pointer to a magic string that is
shorter than 13 characters and is guaranteed to differ from
.IR setting .
This behavior is safe for older applications which assume that
.B crypt
can't fail, when both setting new passwords and authenticating against
existing password hashes.
.BR crypt_rn " and " crypt_ra
return NULL to indicate failure. All four functions set
.I errno
when they fail.
.PP
The functions
.crypt_gensalt and
return a pointer to the compiled string for
.IR setting ,
or NULL on error in which case
.I errno
is set.

.SH HASHING METHODS
The implemented hashing methods are intended specifically for processing
user passwords for storage and authentication;
they are at best inefficient for most other purposes.
.PP
It is important to understand that password hashing is not a replacement
for strong passwords.
It is always possible for an attacker with access to password hashes
to try guessing candidate passwords against the hashes.
There are, however, certain properties a password hashing method may have
which make these key search attacks somewhat harder.
.PP
All of the hashing methods use salts such that the same
.I key
may produce many possible hashes.
Proper use of salts may defeat a number of attacks, including:
.TP
1.
The ability to try candidate passwords against multiple hashes at the
price of one.
.TP
2.
The use of pre-hashed lists of candidate passwords.
.TP
3.
The ability to determine whether two users (or two accounts of one user)
have the same or different passwords without actually having to guess
one of the passwords.
.PP
The key search attacks depend on computing hashes of large numbers of
candidate passwords.
Thus, the computational cost of a good password hashing method must be
high \- but of course not too high to render it impractical.
.PP
All hashing methods implemented within the
.crypt and
interfaces use multiple iterations of an underlying cryptographic
primitive specifically in order to increase the cost of trying a
candidate password.
Unfortunately, due to hardware improvements, the hashing methods which
have a fixed cost become increasingly less secure over time.
.PP
In addition to salts, modern password hashing methods accept a variable
iteration
.IR count .
This makes it possible to adapt their cost to the hardware improvements
while still maintaining compatibility.
.PP
The following hashing methods are or may be implemented within the
described interfaces:
.PP
.de hash

.TP
.I prefix
.ie "\\$1"" \{\
"" (empty string);
.br
a string matching ^[./0-9A-Za-z]{2} (see

.ti -2
.B Traditional DES-based
.br
This method is supported by almost all implementations of
.BR crypt .
Unfortunately, it no longer offers adequate security because of its many
limitations.
Thus, it should not be used for new passwords unless you absolutely have
to be able to migrate the password hashes to other systems.

.PP

.B Extended BSDI-style DES-based
.br
This method is used on BSDI and is also available on at least NetBSD,
OpenBSD, and FreeBSD due to the use of David Burren's FreeSec library.

.PP
.ti -2
.B FreeBSD-style MD5-based
.br
This is Poul-Henning Kamp's MD5-based password hashing method originally
developed for FreeBSD.
It is currently supported on many free Unix-like systems, on Solaris 10
and newer, and it is part of the official glibc.
Its main disadvantage is the fixed iteration count, which is already
too low for the currently available hardware.
.hash "$1$" "\e$1\e$[^$]{1,8}\e$[./0-9A-Za-z]{22}" unlimited 8 "" 128 "6 to 48" 1000

.BR "OpenBSD-style Blowfish-based" " (" bcrypt )
.br
.B bcrypt
was originally developed by Niels Provos and David Mazieres for OpenBSD
and is also supported on recent versions of FreeBSD and NetBSD,
on Solaris 10 and newer, and on several GNU/*/Linux distributions.
It is, however, not part of the official glibc.
.PP
While both
.B bcrypt
and the BSDI-style DES-based hashing offer a variable iteration count,
.B bcrypt
may scale to even faster hardware, doesn't allow for certain optimizations
specific to password cracking only, doesn't have the effective key size
limitation, and uses 8-bit characters in passwords.
.hash "$2b$" "\e$2[abxy]\e$[0-9]{2}\e$[./A-Za-z0-9]{53}" 72 8 "" 184 128 "2**4 to 2**99 (current implementations are limited to 2**31 iterations)"
.PP
With
.BR bcrypt ,
the
.I count
passed to
.crypt_gensalt and
is the base-2 logarithm of the actual iteration count.
.PP
.B bcrypt
hashes used the "$2a$" prefix since 1997.
However, in 2011 an implementation bug was discovered in crypt_blowfish
(versions up to 1.0.4 inclusive) affecting handling of password characters with
the 8th bit set.
Besides fixing the bug,
to provide for upgrade strategies for existing systems, two new prefixes were
introduced: "$2x$", which fully re-introduces the bug, and "$2y$", which
guarantees correct handling of both 7- and 8-bit characters.
OpenBSD 5.5 introduced the "$2b$" prefix for behavior that exactly matches
crypt_blowfish's "$2y$", and current crypt_blowfish supports it as well.
Unfortunately, the behavior of "$2a$" on password characters with the 8th bit
set has to be considered system-specific.
When generating new password hashes, the "$2b$" or "$2y$" prefix should be used.
(If such hashes ever need to be migrated to a system that does not yet support
these new prefixes, the prefix in migrated copies of the already-generated
hashes may be changed to "$2a$".)
.PP
.crypt_gensalt and
support the "$2b$", "$2y$", and "$2a$" prefixes (the latter for legacy programs
or configurations), but not "$2x$" (which must not be used for new hashes).
.crypt and
support all four of these prefixes.
.SH PORTABILITY NOTES
Programs using any of these functions on a glibc 2.x system must be
linked against
.BR libcrypt .
However, many Unix-like operating systems and older versions of the
GNU C Library include the
.BR crypt " function in " libc .
.PP
The
.BR crypt_r ,
.BR crypt_rn ,
.BR crypt_ra ,
.crypt_gensalt and
functions are very non-portable.
.PP
The set of supported hashing methods is implementation-dependent.
.SH CONFORMING TO
The
.B crypt
function conforms to SVID, X/OPEN, and is available on BSD 4.3.
The strings returned by
.B crypt
are not required to be portable among conformant systems.
.PP
.B crypt_r
is a GNU extension.
There's also a
.B crypt_r
function on HP-UX and MKS Toolkit, but the prototypes and semantics differ.
.PP
.B crypt_gensalt
is an Openwall extension.
There's also a
.B crypt_gensalt
function on Solaris 10 and newer, but the prototypes and semantics differ.
.PP
.BR crypt_rn ,
.BR crypt_ra ,
.BR crypt_gensalt_rn ,
and
.B crypt_gensalt_ra
are Openwall extensions.
.SH HISTORY
A rotor-based
.B crypt
function appeared in Version 6 AT&T UNIX.
The "traditional"
.B crypt
first appeared in Version 7 AT&T UNIX.
.PP
The
.B crypt_r
function was introduced during glibc 2.0 development.
.SH BUGS
The return values of
.BR crypt " and " crypt_gensalt
point to static buffers that are overwritten by subsequent calls.
These functions are not thread-safe.
.RB ( crypt
on recent versions of Solaris uses thread-specific data and actually is
thread-safe.)
.PP
The strings returned by certain other implementations of
.B crypt
on error may be stored in read-only locations or only initialized once,
which makes it unsafe to always attempt to zero out the buffer normally
pointed to by the
.B crypt
return value as it would otherwise be preferable for security reasons.
The problem could be avoided with the use of
.BR crypt_r ,
.BR crypt_rn ,
or
.B crypt_ra
where the application has full control over output buffers of these functions
(and often over some of their private data as well).
Unfortunately, the functions aren't (yet?) available on platforms where
.B crypt
has this undesired property.
.PP
Applications using the thread-safe
.B crypt_r
need to allocate address space for the large (over 128 KB)
.I struct crypt_data
structure. Each thread needs a separate instance of the structure. The
.B crypt_r
interface makes it impossible to implement a hashing algorithm which
would need to keep an even larger amount of private data, without breaking
binary compatibility.
.B crypt_ra
allows for dynamically increasing the allocation size as required by the
hashing algorithm that is actually used. Unfortunately,
.B crypt_ra
is even more non-portable than
.BR crypt_r .
.PP
Multi-threaded applications or library functions which are meant to be
thread-safe should use
.BR crypt_gensalt_rn " or " crypt_gensalt_ra
rather than
.BR crypt_gensalt .

* This code comes from John the Ripper password cracker, with reentrant

* cracking removed.

* it if you give credit where it is due and keep your modifications in
* the public domain as well, but I don't require that in order to let
* you place this code and any modifications you make under a license
* of your choice.
*
* This implementation is fully compatible with OpenBSD's bcrypt.c for prefix
* "$2b$", originally by Niels Provos <provos at citi.umich.edu>, and it uses
* some of his ideas. The password hashing algorithm was designed by David
* Mazieres <dm at lcs.mit.edu>. For information on the level of
* compatibility for bcrypt hash prefixes other than "$2b$", please refer to
* the comments in BF_set_key() below and to the included crypt(3) man page.
*
* There's a paper on the algorithm that explains its design decisions:
*
* http://www.usenix.org/events/usenix99/provos.html
*
* Some of the tricks in BF_ROUND might be inspired by Eric Young's
* Blowfish library (I can't be sure if I would think of something if I
* hadn't seen his code).

* There was a sign extension bug in older revisions of this function. While
* we would have liked to simply fix the bug and move on, we have to provide
* a backwards compatibility feature (essentially the bug) for some systems and
* a safety measure for some others. The latter is needed because for certain
* multiple inputs to the buggy algorithm there exist easily found inputs to
* the correct algorithm that produce the same hash. Thus, we optionally
* deviate from the correct algorithm just enough to avoid such collisions.
* While the bug itself affected the majority of passwords containing
* characters with the 8th bit set (although only a percentage of those in a
* collision-producing way), the anti-collision safety measure affects
* only a subset of passwords containing the '\xff' character (not even all of
* those passwords, just some of them). This character is not found in valid
* UTF-8 sequences and is rarely used in popular 8-bit character encodings.
* Thus, the safety measure is unlikely to cause much annoyance, and is a
* reasonable tradeoff to use when authenticating against existing hashes that
* are not reliably known to have been computed with the correct algorithm.
*
* We use an approach that tries to minimize side-channel leaks of password

* This version of the assembly code is optimized primarily for the original
* Intel Pentium but is also careful to avoid partial register stalls on the
* Pentium Pro family of processors (tested up to Pentium III Coppermine).
*
* It is possible to do 15% faster on the Pentium Pro family and probably on
* many non-Intel x86 processors, but, unfortunately, that would make things
* twice slower for the original Pentium.
*
* An additional 2% speedup may be achieved with non-reentrant code.

# We can't use automake's automatic dependency tracking, because it

# using bootstrap-lean, prev-gcc is removed after each stage. When
# running "make install", those header files will be gone, causing the
# library to be rebuilt at install time. That may not succeed.
# These manual dependencies do not include dependencies on unwind.h,
# even though that is part of GCC, because where to find it depends on

# libbacktrace
A C library that may be linked into a C/C++ program to produce symbolic backtraces
Initially written by Ian Lance Taylor <iant@golang.org>.
This is version 1.0.
It is likely that this will always be version 1.0.
The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.
Sample uses would be to print a detailed backtrace when an error
occurs or to gather detailed profiling information.
In general the functions provided by this library are async-signal-safe,
meaning that they may be safely called from a signal handler.
The libbacktrace library is provided under a BSD license.
See the source files for the exact license text.
The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.
Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.
See the source file backtrace-supported.h.in for the macros that it
defines.
As of October 2020, libbacktrace supports ELF, PE/COFF, Mach-O, and
XCOFF executables with DWARF debugging information.
In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX.
The library is written to make it straightforward to add support for
other object file and debugging formats.
The library relies on the C++ unwind API defined at
https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html
This API is provided by GCC and clang.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>

Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation

# STRIPPROG with the value of the STRIP variable (set by the user).

# serial 4 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

# serial 4 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.
