Encoding and Encryption Methods

Huffman method uses a variable-length prefix code for encoding.
Encryption method that aims to keep character strings secret is encryption.
Encryption is defined as the process of converting plaintext or readable data into unreadable ciphertext to protect it from unauthorized access.
Replacement table is used in the Substitution method of encryption.
RSA method is associated with Asymmetric encryption, which uses a pair of keys: a public key for encryption and a private key for decryption.
