Revision	Date	Author	Comments
1.16	21-Oct-2019	jhigh	adding argon2 support to libcrypt. argon2 user authentication now available via MKARGON2=yes (3 variants supported; argon2id recommended) before using, please read argon2 paper at https://github.com/P-H-C/phc-winner-argon2
1.15	16-Sep-2011	joerg	branches: 1.15.42; Use __dead
1.14	05-Mar-2006	christos	PR/31144: YOMURA Masanori: pwhash -S/-b never use optarg
1.13	02-Jun-2005	lukem	appease gcc -Wuninitialized
1.12	12-Jan-2005	christos	more cleanups, WARNS=3
1.11	12-Jan-2005	christos	Use pw_gensalt() instead of using the cipher functions directly. Simplifies the code a lot.
1.10	11-Jan-2005	christos	- use the gensalt functions from libcrypt instead of rolling our own.
1.9	17-Nov-2004	wiz	Merge single-letter options; sync order in man page and usage.
1.8	01-Nov-2004	dsl	Add (unsigned char) cast to ctype functions
1.7	12-Oct-2004	sjg	Apply patch from PR 26779 and update man page (not quite per PR 26780).
1.6	02-Jul-2004	sjg	Add support for SHA1 hashed passwords. The algorithm used is essentially PBKDF1 from RFC 2898 but using hmac_sha1 rather than SHA1 directly (suggested by smb@research.att.com). * The format of the encrypted password is: * $<tag>$<iterations>$<salt>$<digest> * * where: * <tag> is "sha1" * <iterations> is an unsigned int identifying how many rounds * have been applied to <digest>. The number * should vary slightly for each password to make * it harder to generate a dictionary of * pre-computed hashes. See crypt_sha1_iterations. * <salt> up to 64 bytes of random data, 8 bytes is * currently considered more than enough. * <digest> the hashed password. hmac.c implementes HMAC as defined in RFC 2104 and includes a unit test for both hmac_sha1 and hmac_sha1 using a selection of the Known Answer Tests from RFC 2202. It is worth noting that to be FIPS compliant the hmac key (password) should be 10-20 chars.
1.5	14-Jul-2003	itojun	use bounded string op
1.4	23-Jun-2003	agc	Add NetBSD RCS Ids.
1.3	02-Oct-2002	jdolecek	couple minor changes: * move buffer[] to print_passwd(); it's used only there * make trim(), usage(), print_passwd() static, and g/c no longer needed prototypes for them * replace __progname with getprogname()/setprogname() * move the prototypes for pwd_getsalt()/to64() outside of print_passwd() change reviewed by Niels
1.2	02-Oct-2002	wiz	Add NetBSD RCS Id. Sort options.
1.1	01-Oct-2002	provos	password hashing utility that allows des, md5 or bcrypt passwords to be created in scripts; tool originally from downsj@openbsd.org; approved by perry.
1.15.42.1	13-Apr-2020	martin	Mostly merge changes from HEAD upto 20200411
