Encryption Algorithms - TOML

Encryption algorithms are mathematical methods used to protect the confidentiality and integrity of data. They are classified into three main categories: symmetric encryption (secret key), asymmetric encryption (public key), and hash functions. Representative algorithms include AES, RSA, ECC, and SHA-256, which are widely used in various fields such as TLS/SSL communications, digital signatures, password protection, and blockchain. Algorithms recommended by standardization bodies such as NIST have been verified for security and performance.
