Mujahedeen Secrets

Mujahedeen Secrets (transliterated Arabic: Asrar al-Mujahedeen) is an encryption program for Microsoft Windows. It was publicly offered to supporters of Al-Qaeda as a tool to protect the confidentiality of their electronic messages. The authors of the software are anonymous.

Uses
The software allows users to encrypt and decrypt text messages and files with a range of encryption techniques. This is primarily to ensure that any parties intercepting the messages during transmission, such as via Internet e-mail or cellphone, cannot easily view the message's contents.
