Is it possible to decrypt sha512? If you do have a website with the algorithm or a Node package that you can tell me about?

Sha is not a form of encryption, there is no way back to the original value.
If you need encryption, take a look Crypto-js
A hash (or scrutiny) is a sequence of bits generated by a scatter algorithm, usually represented on a hexadecimal basis, which allows visualization in letters and numbers (0 to 9 and A to F), representing a Nibble each. The theoretical concept says that "hash is the transformation of a large amount of data into a small amount of information".
This sequence seeks to identify a file or information only. For example, an email message, a password, a cryptographic key, or even a file. It is a method to transform data in such a way that the result is (almost) unique. In addition, functions used in encryption ensure that it is not possible from a hash value to return to the original information.

SHA is a hash algorithm, not encryption, so there’s no going back to the original value.
