WebPGP follows a three-step process: Step 1: PGP generates a huge, one-time-use public encryption algorithm that cannot be guessed, which becomes the random session key. … WebThis is also referred to as symmetric key encryption. There are two types of symmetric algorithms (or ciphers): stream and block. A block cipher divides the data into blocks (often 64-bit blocks, but newer algorithms sometimes use 128-bit blocks) and encrypts the data one block at a time. Stream ciphers encrypt the data as a stream of bits, one ...
