A stream cipher is an encryption method in which data is encrypted one byte at a time. In this method, a cryptographic key and algorithm are applied to each binary digit in a plaintext data stream to ...

In cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Transposition ciphers keep all the original bits of ...

Determining which algorithm to use in an encrypted communications session. When encryption is required, and one node signals another to begin a transmission session, there are often several ...

An encryption method that works with continuous streams of input rather than fixed blocks. Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an ...
