SHA-512
Powerful SHA-512 cryptographic hash for maximum security and large data integrity
Short explanation
SHA-512 is a SHA-2 hash function with a 512-bit output. It is strong, standardized, and often fast on 64-bit CPUs, making it useful for high-security digests and large data.
Example input
large-release-archive.tar.zstTypical use
Use SHA-512 when you want a larger digest than SHA-256 or when your platform benefits from SHA-512 performance on 64-bit hardware.
When to use it
- High-security file integrity and signed metadata workflows.
- Systems that standardize on SHA-512 or need a 512-bit digest.
- 64-bit environments where SHA-512 performance is strong.
When not to use it
- Password storage without a slow, salted password hashing scheme.
- Compact identifiers where SHA-256 is already more than enough.
- Non-security hashing where speed and short fingerprints matter more than cryptographic strength.
FAQ
Is SHA-512 stronger than SHA-256?
SHA-512 has a larger output and higher security margins, but SHA-256 is already strong for most practical uses.
How long is a SHA-512 hash?
SHA-512 outputs 512 bits, which is 64 bytes or 128 hexadecimal characters.
Should I choose SHA-256 or SHA-512?
Choose SHA-256 for broad compatibility and shorter output. Choose SHA-512 when your protocol, policy, or platform benefits from the larger digest.
