+# Contributing to Tilde Friends
+
+Thank you for your interest in Tilde Friends.
+
+Above all, Tilde Friends aims to be a fun, safe place to play. When that is at
+odds with the course of development, we will work through it with respectful
+communication.
+
+## How can I contribute?
+
+The nature of Tilde Friends makes for a wide range of ways to contribute
+
+- Just use it. Really, just kicking the tires will probably shake out issues
+  in useful ways at this point.
+- Report and comment on bugs: https://dev.tildefriends.net/issues.
+- Make apps. You don't need my permission to make and share apps with Tilde
+  Friends. I hope that an ecosystem of good apps grows outside of this
+  repository. If you want to recreate better versions of the stock apps, just
+  do it. If you make a better ssb app or whatever and drop me a line however
+  is most convenient for you, I will probably take a look and consider
+  replacing the stock one with it.
+- Write about it. Docs in the git repository, blog posts, private messages to
+  me with ideas...really there is no wrong answer. Just make some noise, and
+  I'll do my best to incorporate or otherwise link your feedback and make the
+  most of it.
+- Write C code in the git repository. I'm really striving for it to be the
+  case that other people don't really need to meddle in there, but if you can
+  help out, I will gladly review your pull requests via
+  https://dev.tildefriends.net/pulls.
+
+## Best practices
+
+- The C code is formatted with clang-format. Run `make format`.
+- The rest is formatted with prettier. Run `npm run prettier`.
+- We strive to have code compile on all platforms with no warnings and run with
+  no sanitizer issues.
+- There are tests. Run `out/debug/tildefriends test`.

-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.

-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
-.ad l
-.TP
-.I prefix
-.ie "\\$1"" \{\
-"" (empty string);
-.br
-a string matching ^[./0-9A-Za-z]{2} (see
-.BR regex (7))
-.\}
-.el "\\$1"
-.TP
-.B Encoding syntax
-\\$2
-.TP
-.B Maximum password length
-\\$3 (uses \\$4-bit characters)
-.TP
-.B Effective key size
-.ie "\\$5"" limited by the hash size only
-.el up to \\$5 bits

-.TP
-.B Salt size
-\\$7 bits

-.B Iteration count
-\\$8

-.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.
-.hash "" "[./0-9A-Za-z]{13}" 8 7 56 64 12 25
-.PP
-.ti -2
-.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.
-.hash _ "_[./0-9A-Za-z]{19}" unlimited 7 56 64 24 "1 to 2**24-1 (must be odd)"
-.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
-.PP

-.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 .

- * 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
- * Prefix "$2b$": bug = 0, safety = 0
- * Prefix "$2x$": bug = 1, safety = 0

-# 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.

-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.
