I am aware that it's not possible to reverse lookup a sha 512 hash.

Still I have a query I came across many sites which offer sha 512 encryption and decryption. While trying to decrypt a sha 512 hash they fail to give a result. However when you try to encrypt a string they give exact same sha 512 hash result.

If hashing a string is possible, I mean for a string when you generate a sha 512 hash, you will always get a same hash result then why it can't be decrypted or reverse lookup.

Don't you think, we are actually missing something while trying to decrypt a sha 512 hash.

    Hashing is not encryption. Cryptographic Hash functions are one way-functions... The web-site are building some tables especially, rainbow tables so that when you asking them a hash value, if it is on the table they provide it for you. If not, forget it. – kelalaka Oct 05 '21 at 10:40
