CryptoLib4Pascal: Crypto for Modern Object Pascal

CryptoLib4Pascal is an Object Pascal cryptographic library released under the permissive MIT License.

CryptoLib4Pascal's goal is to be the best option for cryptography in Object Pascal by offering cryptographic recipes and primitives to Object Pascal developers.

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