What sha-512 hash generator does
SHA-512 is computed with the Web Crypto API. Same bytes always produce the same digest. Empty input hashes the empty byte string. Optional HMAC uses the same algorithm. This page does not decrypt hashes.
How this page works

Questions
Does this page upload what I type?
No. The work runs in the page you opened. CZNull does not receive the input.
Is a hash encryption?
No. Anyone can hash the same bytes and compare. You cannot recover the input from the digest.
When should I use HMAC?
When the digest must depend on a key as well as the message. CRC-32 has no HMAC on this site.
Empty input?
The empty byte string has a defined digest. That is not an error.
