MAXA Crypt Portable allows you to encrypt files, directory structures and texts using the 256-bit Rijndael algorithm, winner of the Advanced Encryption Standard contest. Multiple files can be encrypted into one file and are even compressed in their size.
The program is smaller than 500kb and can be run on every Windows-computer (on Linux as well using Wine) without need of installation and therefore is ideal for use on Portable storage media (like USB-Sticks).
Furthermore, the online interface can be used to encrypt/decrypt texts and even send sensitive data encrypted by mail.
