Cryptography - (Ciphertext|cyphertext|Message Digest|Digest)


In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher.


Message digest

In the context of hashing / data integrity, the cyphertext is known as digest or message digest in the context of

The message is digested by a hash function
