PlexCrypt is a graphical based software that allows
set of files or folders to compress using Zip format.
PlexCrypt supports both asynchronous encryption based on Public-Key-Infrastructu
re (PKI) and synchronous encryption based on passwords.
In addition, it encrypts and decrypts set of files
or set of folders using AES, Blowfish, CAST, DES,
ElGamal, IDEA, IES, RC4, RC6, RSA, Rijndael, Serpent
Skipjack, Twofish, etc. PlexCrypt can create self-decrypting files.
In addition, it allows
users to create and manage digital certificates
for encryption.

Pivo SSH was developed for commercial organization for securing remote shell access. The protocol supports compression and tunneling multiple TCP connections over one secured connection. SSH supports various authentication schemes such as password-based, keyboard-interactive, allowing the client authorize itself using several schemes at the same time. Some SSH implementations also support PKI infrastructure for server and client authentication.
