Cryptographic Hash Functions
- SHA-1: 160-bit (40 hex chars). Deprecated for security — avoid for passwords or signatures.
- SHA-256: 256-bit (64 hex chars). Industry standard for checksums, HMAC, certificates.
- SHA-384: 384-bit (96 hex chars). Part of SHA-2 family, used in TLS.
- SHA-512: 512-bit (128 hex chars). Strongest in SHA-2 family. Use for high-security needs.
Note: Hashing is one-way — you cannot reverse a hash to get the original text. This tool
