SHA-512 Hash Generator
SHA-512 is a 512-bit member of the SHA-2 family. The digest is 128 hex characters. Use it when you want a longer checksum than SHA-256, or when a spec calls for SHA-512 explicitly.
Worked example: SHA-512 of a short string
Input

Practical tip
SHA-512 can be faster than SHA-256 on 64-bit CPUs. For most APIs, SHA-256 remains the default because the extra length is rarely needed.

SHA-512 Hash Generator FAQs
How long is a SHA-512 hash?
512 bits, 128 hexadecimal characters.
Is SHA-512 more secure than SHA-256?
Both are strong. SHA-512 has a larger digest, which matters more for HMAC key strength and collision resistance at extreme scale than for everyday checksums.
