NAME

       crypt_bsdmd5 - password hashing module using MD5 message hash algorithm

SYNOPSIS

       /usr/lib/security/$ISA/crypt_bsdmd5.so

DESCRIPTION

       The crypt_bsdmd5 module is a one-way password hashing module for use with crypt(3C) that uses the MD5 message hash algorithm. The algorithm
       identifier for crypt.conf(4) and policy.conf(4) is 1. The output is compatible with md5crypt on BSD and Linux systems.

       The maximum password length for crypt_bsdmd5 is 255 characters.

NAME

       crypt_unix - traditional UNIX crypt algorithm

DESCRIPTION

       The  crypt_unix algorithm is the traditional UNIX crypt algorithm. It is not considered sufficiently secure for current systems and is pro-
       vided for backwards compatibility. The crypt_sunmd5(5), crypt_bsdmd5(5), or crypt_bsdbf(5) algorithm should be used instead.

       The algorithm identifier for policy.conf(4) is __unix__. There is no entry in crypt.conf(4) for this algorithm.

       The crypt_unix algorithm is internal to libc and provides the string encoding function used by crypt(3C) when the first	character  of  the
       salt is not a "$".

       This algorithm is based on a one-way encryption algorithm with variations intended (among other things) to frustrate use of hardware imple-
       mentations of a key search.  Only the first eight characters of the key passed to crypt() are  used  with  this	algorithm;  the  rest  are
       silently  ignored.  The salt is a two-character string chosen from the set [a-zA-Z0-9./].  This string is used to perturb the hashing algo-
       rithm in one of 4096 different ways.

       The maximum password length for crypt_unix is 8 characters.

USAGE

       The return value of the crypt_unix algorithm might not be portable among standard-conforming systems. See standards(5).
