Calculate the SHA-512 hash of any text
A SHA-512 hash is 512 bits, shown as 128 hexadecimal characters, and has no known practical attacks. It works on 64-bit words, so on 64-bit CPUs it is often faster than SHA-256 for long inputs. SHA-256 is enough for most uses and gives shorter digests.

Not on its own: it is too fast. Use Argon2id, bcrypt or scrypt. The crypt(3) scheme “SHA-512 crypt” used by Linux adds a salt and thousands of rounds, which is different from a single SHA-512 hash.
