WebDecryption of a ciphertext is a reverse process. User first decrypt using K 3, then encrypt with K 2, and finally decrypt with K 1. Due to this design of Triple DES as an encrypt–decrypt–encrypt process, it is possible to use a 3TDES (hardware) implementation for single DES by setting K 1, K 2, and K 3 to be the same value. This … WebIt combines private-key and public-key cryptography and the use of symmetric and asymmetric key technology to encrypt data as it travels across networks. PGP 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.
