Overview#

A Cipher (or cypher) is an algorithm for performing Encryption or decryption.

Cipher that uses the same key to both Encryption and Decryption is a symmetric cipher.

asymmetric ciphers use a different keys for Encryption and Decryption. Typically we use a Private Key for Encryption and a Public Key for Decryption.

Cipher Types#

Ciphers are one of:

• Block Cipher - which is normally used in a Block Cipher Mode
• Stream Cipher

Cipher Encryption#

A Cipher uses a key and transforms a Plaintext message into Ciphertext.
