Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext) decryption is the process of converting ciphertext back to plaintext. Decryption is the reverse, in other words, moving from the unintelligible ciphertext back to plaintext a cipher (or cypher) is a pair of algorithms that create the encryption and the reversing decryption.
