.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`apache_md5_crypt()\*(C'\fR provides a function compatible with Apache's \f(CW\*(C`.htpasswd\*(C'\fR files.
This was contributed by Bryan Hart <bryan@eai.com>.
This function is exported by default.
.PP
The \f(CW\*(C`unix_md5_crypt()\*(C'\fR provides a \fIcrypt()\fR\-compatible interface to the rather new MD5\-based \fIcrypt()\fR function
found in modern operating systems. It's based on the implementation found on FreeBSD 2.2.[56]\-RELEASE.
This function is also exported by default.
.PP
For both functions, if a salt value is not supplied, a random salt will be
generated, using the function \fIrandom_md5_salt()\fR.
This function is not exported by default.

.ie n .SS "apache_md5_crypt($password, $salt)"
.el .SS "apache_md5_crypt($password, \f(CW$salt\fP)"
.IX Subsection "apache_md5_crypt($password, $salt)"
This sets a magic variable, and then passes all the calling parameters to \*(L"unix_md5_crypt($password, \f(CW$salt\fR)\*(R".
.PP
Returns an encrypted version of the given password.
.PP
Basically, it's a very poor choice for anything other than password authentication.
.SS "random_md5_salt([$length])"
.IX Subsection "random_md5_salt([$length])"
Here, [] indicate an optional parameter.
.PP
Returns a random salt of the given length.
.PP
The maximum length is 8.
.PP
If \f(CW$length\fR is omitted, it defaults to 8.
.ie n .SS "unix_md5_crypt($password, $salt)"
.el .SS "unix_md5_crypt($password, \f(CW$salt\fP)"
.IX Subsection "unix_md5_crypt($password, $salt)"
Returns an encrypted version of the given password.
