CHAOS Messenger is the utility program that creates active Chaos files for Windows.

Active Chaos files are executable programs (EXEs) that contain a Chaos file and the software necessary to decrypt the information and encrypt answer messages. Users can create active executable Chaos files that anyone can use to encrypt messages with the proper password.

No other software is required. These active Chaos files are ideal for safe electronical distribution of the information because they contain multiple compressed and encrypted files and folders.

This feature is especially convenient for sending encrypted files to people who do not have PGP or CHAOS Public Key installed.
