Description
-----------

[](#description)

unix\_md5\_crypt() provides a crypt()-compatible interface to the rather new MD5-based crypt() function found in modern operating systems. It's based on the implementation found on FreeBSD 2.2.\[56\]-RELEASE and contains the following license in it:

```
"THE BEER-WARE LICENSE" (Revision 42):
 wrote this file.  As long as you retain this notice you
can do whatever you want with this stuff. If we meet some day, and you think
this stuff is worth it, you can buy me a beer in return.   Poul-Henning Kamp

```

apache\_md5\_crypt() provides a function compatible with Apache's .htpasswd files. This was contributed by Bryan Hart ().
