Study Notes
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.
