HashLib4Pascal: Hashing for Modern Object Pascal

HashLib4Pascal is an Object Pascal hashing library released under the permissive MIT License which provides an easy to use interface for computing hashes and checksums of data. It also supports state based (incremental) hashing.

HashLib4Pascal's goal is to be the best option for hashing in Object Pascal by offering various hashing primitives via an easy to use API to Object Pascal developers.

Development is coordinated on GitHub and contributions are welcome. If you need help, please open an issue here.
