About SHA Hashing
SHA (Secure Hash Algorithm) is a family of cryptographic hash functions. They produce a fixed-size hash value from any input data.
- SHA-1: 160-bit hash (deprecated for security-critical uses)
- SHA-256: 256-bit hash (widely used, recommended)
- SHA-512: 512-bit hash (more secure, larger output)
