About SHA-512
What is SHA-512?
SHA-512 (Secure Hash Algorithm 512-bit) produces a 64-byte digest typically represented as a 128-character hexadecimal string.
Outputs
- 512-bit digest (64 bytes)
- HEX (128 chars) or Base64
- Deterministic & one-way
Best Practices
Use SHA-512 for checksums and integrity. For authentication use HMAC-SHA512.
Common Uses
- File integrity verification
- API signing (HMAC-SHA512)
- Data fingerprinting
