Frequently asked questions
- When is SHA-512 a better choice than SHA-256?
- On 64-bit hardware SHA-512 is often faster than SHA-256 because it operates on 64-bit words natively. It also offers a larger 512-bit output, making it useful for high-security checksums, long-lived audit logs, and key derivation seeds.
- How long is a SHA-512 digest?
- SHA-512 produces a 512-bit hash, shown as 128 hexadecimal characters (or 88 in Base64).
- Is SHA-512 stronger than SHA-256 in practice?
- For practical security both are uncrackable today. SHA-512 has more output bits, which raises the collision-finding floor from 2^128 to 2^256, but that margin only matters for extreme security or quantum-resilient designs.
