A very small, very simple, yet very secure encryption tool.

Encrypto lets you encrypt files before sending them to friends or coworkers. Drop a file into Encrypto, set a password, and then send it with added security.

AES Crypt for Windows (30-day trial)

Encrypt and decrypt whole files or their parts using AES, 3-DES, RC2, and DES symmetric algorithms. You can encrypt files with a single password or specify cryptographic keys (vectors) instead. You can change key bit length for better protection.
