About SHA-512

SHA-512 produces a 512-bit digest, written as 128 hexadecimal characters. The same input always produces the same hash, while even a one-character change yields a completely different output. This page's hash is exactly 128 characters long, as expected for SHA-512.

Security: SHA-512 is secure and the larger member of the SHA-2 family. Its 512-bit digest gives a wider security margin than SHA-256, at a slightly higher computational cost. It is most appropriate for high-assurance signatures and integrity checks where a larger margin is wanted.

Can this hash be reversed?

Hashing is one-way — you cannot mathematically reverse a SHA-512 hash to recover its input. However, precomputed (rainbow) tables can simply look up the hashes of common inputs, so a common dictionary word like "secret" should never be used as a password. Strong passwords are long, random, and salted before hashing.

Frequently Asked Questions

What is the SHA-512 hash of "secret"?▾

The SHA-512 hash of "secret" is bd2b1aaf7ef4f09be9f52ce2d8d599674d81aa9d6a4421696dc4d93dd0619d682ce56b4d64a9ef097761ced99e0f67265b5f76085e5b0ee7ca4696b2ad6fe2b2.

Is SHA-512 secure?▾

SHA-512 is secure and the larger member of the SHA-2 family. Its 512-bit digest gives a wider security margin than SHA-256, at a slightly higher computational cost.

How long is a SHA-512 hash?▾

A SHA-512 hash is 512-bit, which is 128 hexadecimal characters long.

Can a SHA-512 hash be reversed?▾

No. SHA-512 is a one-way function, so a hash cannot be mathematically reversed back to its input. However, hashes of common inputs can be looked up in precomputed (rainbow) tables — which is why a common word like "secret" should never be used as a password.
