WebDecryption. In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). WebNumber one: ciphertext only case. Sometimes, cryptanalysis has some ciphertext. But they may not have the corresponding plain text. Typically, not knowing, The key, they do not have the encryption or the decryption function. Second case: known plain text case. Some, the cryptanalysists know some match a pair of cipher attacks and the plain text. inward beauty quotes
