Delphi has its hashing unit which helps you to hash with a number of different hashes including MD5, Bob Jenkins, SHA1, and SHA 2 (SHA224, SHA256, SHA384, SHA512, SHA512_224, SHA512_256). But, if you need some other hashing algorithms for your project you can use a free and open-source library called HashLib4Pascal.
HashLib4Pascal is an Object Pascal hashing library released under the permissive MIT License, which implements 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.
