encsh is a simple tool that encrypts a shell or other interpreted script and puts a wrapper around it. The end result is an executable which, when given the correct password, will be decrypted and run through a pipe, effectively keeping the plain text of the script away from the disk.
Birch is a simple proxy or tunnel application with a filter mechanism for line based application protocols built on TCP. Initially it was written to add encryption in a transparent way to the IRC protocol but as the encryption mechanism is implemented in a modular way, it is not restricted to just supporting encryption. Filters can be supplied via Java's Service Provider mechanism. A CLI and a GUI are available.
DComSoft SWF Protector makes source code inaccessible for SWF decompilers. It lets you encrypt all ActionScript classes or select the most sensitive ones. It features four reliable protection algorithms, full support for AS 2.0 and AS 3.0, two protection modes (Simple and Advanced), a choice of protection method and its intensity in Advanced mode, batch file protection in Simple mode, and the possibility to get full file information.
CF is a Linux/Unix command line utility for editing/managing AES-encrypted text files. Multiple users can edit the same files using their own separate passwords. It supports basic file locking, piping, adding, changing, removing, and listing keys. Editing sessions are as simple as typing "cf secretfile.cf"; CF asks for a password, decrypts the file, and starts an editor of choice. When the sessions ends, CF picks up the clear text and re-encrypts it. It takes care to let the clear files exist for as short periods of time as possible, and wipes them from memory and disk. It can be used for password management for single users or groups. It can also encrypt/decrypt streams when used in a pipe.
The PHP Code Encryption class can be used to obfuscate PHP scripts by replacing variable names. It can parse a given PHP script and replace the names of the variables it uses with more obfuscated names. The new names of the replaced variables can be retrieved by looking at a variable of the class.
