65ed10d75c Do not seed the random number generator each time, and use the time in
microseconds to avoid having the same salt for different passwords
generated in the same second.  This permits to avoid using the same salt
for different passwords in newusers.

ae99674e9b Fix build failures with --disable-shadowgrp. Thanks to Jürgen
Daubert for the patch.
* libmisc/salt.c: Include <stdio.h>, needed for stderr and printf
  functions.
* lib/encrypt.c: Include <stdio.h>, needed for perror, stderr and
  printf functions
* src/usermod.c: sgr_locked exists only if SHADOWGRP is defined.
* src/chgpasswd.c: Only check is the gshadow file exists if
  SHADOWGRP is defined.

e663f6c0b4 * libmisc/salt.c: Add prototype for l64a(), gensalt(),
SHA_salt_size(), and SHA_salt_rounds().
* libmisc/salt.c: l64a() and gensalt() are static.
* libmisc/salt.c: The `meth' parameter of crypt_make_salt() is a
  const. (ditto for the method variable).
* libmisc/salt.c: SHA_salt_rounds returns a const string.
* libmisc/salt.c: Avoid warnings with cast of random() to double.
* libmisc/salt.c: Replace rand() by random().

4d606cc690 * configure.in: New configure option: --with-sha-crypt enabled by
default. Keeping the feature enabled is safe. Disabling it permits
  to disable the references to the SHA256 and SHA512 password
  encryption algorithms from the usage help and manuals (in addition
  to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: ENCRYPT_METHOD is
  always supported in login.defs. Remove the ENCRYPTMETHOD_SELECT
  preprocessor condition.
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: Disable SHA256 and
  SHA512 if USE_SHA_CRYPT is not defined (this corresponds to a
  subset of the ENCRYPTMETHOD_SELECT sections).

a99bec34a9 Make sure method is not NULL, defaulting to DES. Thanks to Dan Kopecek <dkopecek@redhat.com>. 2007-11-23 23:57:47 +00:00

963bfaf521 * Move the srandom call to gensalt.
* Replace the test on salt_size by an assert.

43b10b311a Applied patch shadow-utils-4.0.18.2-salt.patch. Thanks to Dan Kopecek <dkopecek@redhat.com> 2007-11-23 20:51:43 +00:00

9aa40bb96d * libmisc/obscure.c, libmisc/salt.c, src/passwd.c: Match DES, MD5,
SHA256, and SHA512 exactly (not only the first 3/6 chars).
* libmisc/salt.c (SHA_salt_rounds): Set rounds to the specified
  prefered_rounds value, if specified.
* src/gpasswd.c, libmisc/salt.c: Fix compilation warnings (use
  size_t for lengths).
* src/chpasswd.c, src/chgpasswd.c: Add missing parenthesis.

0b695f5a76 * lib/prototypes.h, libmisc/salt.c: Add parameters to
crypt_make_salt to force the crypt method and number of rounds.
* libmisc/salt.c: Add parameter to SHA_salt_rounds to force the
  number of rounds.
* libmisc/salt.c, lib/getdef.c: ENCRYPT_METHOD and MD5_CRYPT_ENAB
  are needed also when USE_PAM (e.g. for chpasswd).
* src/newusers.c, src/gpasswd.c: Use the new crypt_make_salt prototype.
* src/chpasswd.c, src/chgpasswd.c: Add option -c, --crypt-method
  and -s, --sha-rounds to specify the crypt method and number of
  rounds in case of one of the SHA methods. The new prototype of
  crypt_make_salt simplifies the handling of -m, --md5.

e406b7fe4a * libmisc/salt.c: The salt has a random size (between 8 and 16
bytes).
* lib/getdef.c, etc/login.defs: Add definitions for
  SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS.
* libmisc/salt.c: Use SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS
  to add a random number of rounds if needed.

c214b26ee6 * libmisc/salt.c (MAGNUM): Terminate the array with nul (the array
is then used with strcat).
* libmisc/salt.c (crypt_make_salt): Initialize result[0] to nul at
  the beginning (was not initialized when USE_PAM).
* libmisc/salt.c (crypt_make_salt): Check that ENCRYPT_METHOD is a
  valid crypt method.

65f536165d Fix typo introduced while merging RedHat patch shadow-4.0.18.1-sha256.patch. 2007-11-19 22:16:50 +00:00

b8d8d0de00 Add support for SHA256 and SHA512 encrypt methods. Apply RedHat's patch
shadow-4.0.18.1-sha256.patch. Thanks to Peter Vrabec. Hardly no changes
except re-indent and changes related to recent modifications (max_salt_len
in crypt_make_salt). Changes in lib/defines.h not applied (definition of
ENCRYPTMETHOD_SELECT). I will add a configure check or flag.

449f17385a * libmisc/salt.c: Make sure the salt string is terminated at the
right place (either 8th, or 11th position).
 * NEWS, src/chgpasswd.c, src/chpasswd.c: The protocol + salt does
   not need 15 chars. No need for a temporary buffer.
   This change the fix committed on 2007-11-10. The salt provided to
   pw_encrypt could have been too long.
