SHA512 hash generator
This is a free online SHA512 hash generator
How does SHA512 algorithm work?
SHA-512 is a function of cryptographic algorithm SHA-2, which is an evolution of famous SHA-1. SHA-512 is very close to Sha-256 except that it used 1024 bits "blocks", and accept as input a 2^128 bits maximum length string. SHA-512 also has others algorithmic modifications in comparison with Sha-256.
What is SHA512 used for?
SHA-512 is a hashing algorithm that performs a hashing function on some data given to it. Hashing algorithms are used in many things such as internet security, digital certificates and even blockchains
Can SHA512 be decrypted?
SHA-512 is not encryption, it's hashing. You can't decrypt it, that's the whole point with it. You use it by hashing other data and comparing the hash codes to determine if the data is identical to the original.
SHA512 in programming languages
Will the SHA512 cryptographic hash function output be same in all programming languages?
Yes, similar to Md5, sha256, SHA512 generates the same hash code for all programming languages.

SHA512 in Dart
Dart or Flutter convert string to SHA512 hash.
// import the packages
import 'package:crypto/crypto.dart';
import 'dart:convert'; // for the utf8.encode method
// then hash the string
var bytes = utf8.encode("sita.app"); // data being hashed
var digest = sha512.convert(bytes);
print("Digest as hex string: $digest");
//output: Digest as hex string: 4b8bc8386c3803269d6cf0d0a32fa9046dca6726dd4a627156a52add97395639b56a185701817c86c8b5d0138a955fb6fe8ca2482b6527f34c1fae6d8b50951f
