+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

+.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:

+This method is supported by almost all implementations of

+Unfortunately, it no longer offers adequate security because of its many

+Thus, it should not be used for new passwords unless you absolutely have
+to be able to migrate the password hashes to other systems.

+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.

+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.

+.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 implementation is fully compatible with OpenBSD's bcrypt.c for prefix

+ * 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:

+ * 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
+ * information - that is, we mostly use fixed-cost bitwise operations instead
+ * of branches or table lookups.  (One conditional branch based on password
+ * length remains.  It is not part of the bug aftermath, though, and is
+ * difficult and possibly unreasonable to avoid given the use of C strings by
+ * the caller, which results in similar timing leaks anyway.)
+ *
+ * For actual implementation, we set an array index in the variable "bug"
+ * (0 means no bug, 1 means sign extension bug emulation) and a flag in the
+ * variable "safety" (bit 16 is set when the safety measure is requested).
+ * Valid combinations of settings are:
+ *
+ * Prefix "$2a$": bug = 0, safety = 0x10000

+# 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
