Questions

Is SHA-512 more secure than SHA-256?

It has a larger safety margin, but SHA-256 isn't broken either. SHA-512 is often faster on 64-bit computers because it works in 64-bit words. SHA-256 is the more common default.

Why is a SHA-512 hash so long?

The length is set by the algorithm, not your input. SHA-512 is 512 bits, which is 128 hex characters. MD5 is 32 characters and SHA-1 is 40.

Can a SHA-512 hash be turned back into the text?

No. A hash is one-way. The only way to find the input is to guess and check.

Why doesn't my hash match another tool?

This tool hashes your text as UTF-8, like sha512sum. A trailing newline or a different text encoding gives a different hash.

What is the SHA-512 hash of an empty string?
