A simple but powerful cross-platform utility for managing and accessing your most secret data. It stores passwords and whole files, so it can literally store any information you want to keep secret. Access your most-used passwords/URLs right out of a desktop tray icon.

For advanced users, it includes a separate utility called Grypto-Transforms, which has a universal hash calculator with all the major hash functions, generic encrypt/decrypt functions and a base64/hex converter.

Although the interface is simple and intuitive, the security is top-notch. It uses AES with CCM to secure and authenticate the data.
