MD5, SHA, HMAC & file hashing
MD5: Fast but cryptographically broken. Use only for checksums, not security.
SHA-1: Deprecated for security. Still used in some legacy systems.
SHA-256: Recommended for most applications. Part of SHA-2 family.
SHA-512: Stronger variant of SHA-256. Better for password hashing.
