Check Point Pointsec. A stream cipher is a method of encrypting text (to produce ciphertext) in which a cryptographic key and algorithm are applied to each binary digit in a data stream, one bit at a time.This method is not much used in modern cryptography.he main alternative method is the block cipher in which a key and algorithm are applied to blocks of data rather than individual bits in a stream.

Decrypted Text. 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). In many contexts, the word encryption also implicitly refers to the reverse process, decryption (e.g. âsoftware for encryptionâ can typically also perform decryption), to make the encrypted information readable again (i.e. to make it unencrypted).
