Introduction

Stream Cipher

Stream Cipher is a mode of encryption where each byte(sometimes a bit) of plaintext is encrypted with the corresponding byte of the keystream. It is also known as state cipher. Encryption of one byte of plaintext is independent of the other bytes of plaintext. Some examples of stream ciphers are:

  • Substitution Ciphers
  • Transposition Ciphers
  • XOR Cipher
