About Hash Functions

MD5: Fast but cryptographically broken. Use only for simple checksums.

SHA-1: Also deprecated for security. Suitable for legacy compatibility.

SHA-256: Secure and widely used. Part of the SHA-2 family. Recommended for most uses.

SHA-512: Highly secure with a longer output. Best for high-security applications.
