About this tool
SHA-512 produces a 512-bit (128 hex character) hash from the SHA-2 family. Common in TLS, SSH host keys, and code signing. Slower than SHA-256 on 32-bit hardware, often faster than SHA-256 on 64-bit CPUs.
FAQs
When should I prefer SHA-512 over SHA-256?
When you want a longer hash (e.g. for very large input domains) or when running on 64-bit hardware where SHA-512 can be faster.
Is SHA-512 safe for password hashing?
Plain SHA-512 is too fast for password storage. Use bcrypt, scrypt, or Argon2 instead.
What's SHA-512/256?
A truncated variant - SHA-512 internals with a 256-bit output. Not the same as SHA-256.
