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 ...

Block ciphers are invertible symmetric key cryptographic algorithms. Here, symmetric means that the same cryptographic key is used to both encrypt and decrypt messages. The key is used to transform ...

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 ...
