DESCRIPTION

31       apache_md5_crypt() provides a function compatible with Apache's
32       ".htpasswd" files.  This was contributed by Bryan Hart <bryan@eai.com>.
33       This function is exported by default.
34
35       The unix_md5_crypt() provides a crypt()-compatible interface to the
36       rather new MD5-based crypt() function found in modern operating
37       systems. It's based on the implementation found on FreeBSD
38       2.2.[56]-RELEASE.  This function is also exported by default.
39
40       For both functions, if a salt value is not supplied, a random salt will
41       be generated, using the function random_md5_salt().  This function is
42       not exported by default.

METHODS

52   apache_md5_crypt($password, $salt)
53       This sets a magic variable, and then passes all the calling parameters
54       to "unix_md5_crypt($password, $salt)".
55
56       Returns an encrypted version of the given password.
57
58       Basically, it's a very poor choice for anything other than password
59       authentication.
60
61   random_md5_salt([$length])
62       Here, [] indicate an optional parameter.
63
64       Returns a random salt of the given length.
65
66       The maximum length is 8.
67
68       If $length is omitted, it defaults to 8.
69
70   unix_md5_crypt($password, $salt)
71       Returns an encrypted version of the given password.
72
73       Basically, it's a very poor choice for anything other than password
74       authentication.
