SHA-512 FAQ
What is SHA-512?
SHA-512 produces a 512-bit (64-byte) hash and uses 64-bit operations internally. It offers the highest security margin in the SHA-2 family.
SHA-512 vs SHA-256 performance?
SHA-512 is ~50% faster than SHA-256 on 64-bit processors because it uses native 64-bit arithmetic. On 32-bit systems, SHA-256 is faster.
Is 512 bits overkill?
For most applications, yes — but the performance advantage on 64-bit systems makes it a practical choice. The extra bits provide a larger security margin against future attacks.
Can I use SHA-512 for file integrity?
Absolutely. SHA-512 is excellent for file checksums, code signing, and data integrity verification. Many Linux distributions use it for package verification.
