Hash class abstract
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.
Notice custom implementations of this class cannot be passed to to other methods in this library.
