Cyphertext
Cyphertext is Data in its encrypted form 1).
Cyphertext is encrypted text transformed from Plaintext using an Cryptographic Algorithm.
Ciphertext can not be read until it has been converted into Plaintext (using Decryption) with a key. The decryption cipher is an algorithm that transforms the Ciphertext back into Plaintext.
The term cypher is sometimes used as a synonym for cyphertext. However, it refers to the method of encryption rather than the result.
