Hash class Null safety

A cryptographic hash algorithm implementation.

The package:webcrypto/webcrypto.dart library provides the following implementations of this class:

• Hash.sha1, (this is considered weak, only included for compatibility),
• Hash.sha256,
• Hash.sha384, and,
• Hash.sha512.

For a guidance on choice of hash function see NIST SP 800-57 Part 1 Rev 5.

WARNING: Custom implementations of this class cannot be passed to to other methods in this library.
