About SHA-512

SHA-512 produces a 512-bit (128 hex character) hash from the SHA-2 family. It is often faster than SHA-256 on 64-bit processors and offers a bigger safety margin, which is why it appears in password-hashing schemes and high-security systems.

The hash is computed from your text exactly as typed (encoded as UTF-8), including spaces and line breaks. A single extra space gives a completely different result, which is the usual reason hashes “don’t match” between tools. Turn on “Hash each line separately” to process a list.

Frequently asked questions

When should I use SHA-512 instead of SHA-256?

Both are secure. SHA-512 can be faster on 64-bit hardware and gives a longer digest, while SHA-256 is more widely used and gives shorter output.

Can I reverse an SHA-512 hash?

No. Hash functions are one-way. Short or common inputs can be found by guessing, which is why passwords should use dedicated slow hashes such as bcrypt or Argon2.

Is my text sent to a server?

No. The hash is calculated in your browser.
