PSM Encryptor is a cryptography and steganography tool. PSM Encryptor will encrypt any group of files (including whole directory structures) but will also disguise the resulting encrypted archive as a working sound or image file. In addition, PSM Encryptor ships with its own video codec: you can encrypt videos which can then be decrypted in real-time as you watch them, with no noticeable loss of performance or quality. Integrated email engine.
