Icon Tresor 2.2.2

Tresor is a file and folder encryption application for Macintosh. It combines high cryptographic security and ease of use. Integrated compression functions allow compression and encryption in a single pass, without any interim files. Filter functions allow you to automate complex encryption tasks without the use of risky scripts. Being developed outside the US, Tresor is available in all countries that allow cryptography.
Tresor encrypts the complete content of any file using IDEA block encryption. It takes a passphrase of arbitrary length and produces a 160-bit hash value using the Secure Hash Algorithm (SHA). It then takes 128 bits of this hash value, using them as the encryption key for IDEA. For decryption the same passphrase will be needed again.
