SHA-512

Recommended

SHA-512 is the 512-bit variant of the SHA-2 family. It provides a larger hash output and is actually faster than SHA-256 on 64-bit systems. Commonly used when a longer hash is desired for additional security margin.

What is SHA-512?

SHA-512 is a recommended cryptographic hash algorithm that produces a 512 bits (128 hex characters) output. SHA-512 is the 512-bit variant of the SHA-2 family. It provides a larger hash output and is actually faster than SHA-256 on 64-bit systems. Commonly used when a longer hash is desired for additional security margin. It is classified as fast in performance and commonly used for high-security data integrity verification and digital signatures requiring larger hash output.
