crypt++.el is a package of Lisp functions that recognize automatically encrypted and encoded (i.e., compressed) files when they are first visited or written. The BUFFER corresponding to the file is decoded and/or decrypted before it is presented to the user. The file itself is unchanged on the disk. When the buffer is subsequently saved to disk, a hook function re-encodes the buffer before the actual disk write takes place.

DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).

Digest::Perl::MD5 is a pure Perl implementation of RSA's MD5 algorithm. You can install it without a C-compiler. It's really slow compared to Digest::MD5, so you should only use it where you cannot use Digest::MD5.

dirtypgp is a quick-and-dirty wish script to run in a X Window environment. It is a workslate upon which clear or cipher text may be cut and pasted. A series of button controls then are used to convert to and from ciphered and clear text, encoded with the PGP package. It was originally written by Carsten Meyer, who released it under the GPL.
