Vocabulary
- Symmetric Cryptography — An encryption method that uses only one key for both encryption and decryption.
- Asymmetric Cryptography — An encryption method that uses two different keys (a public key and a private key) for encryption and decryption.
- Private Key Cryptography — Another term for symmetric cryptography, emphasizing that the single key used must be kept secret.
- Public Key Cryptography — Another term for asymmetric cryptography, highlighting the use of a publicly available key for encryption.
- Bulk Data — A large amount of data, for which symmetric cryptography is often preferred due to its faster execution.
