Generate MD5, SHA-1, SHA-256, SHA-512, and SHA-3 hashes for text or files
MD5: Fast but not secure, used for checksums and non-security purposes
SHA-1: Deprecated for security, still used for legacy compatibility
SHA-256: Widely used, secure, good balance of speed and security
SHA-512: Most secure, larger hash size, slower but more resistant to attacks
SHA-3: Latest standard, different construction from SHA-2, good for new applications
