Deltacrypt OneClick lets the user create and distribute public keys. Its unalterable Deltacrypt public key files prevent man-in-the-middle attacks where key interception and substitution is at the heart of such attack.
The Deltacrypt application is brute-force attack resistant by simulating decryption process in real decryption time when used with a false private key. All Deltacrypt Encryption applications provide OneClick set of commands for encryption and decryption is just a click. A OneClick creation feature walks the user each step of the way into command creation. No special skills required.
