encryption-suite is a Java cryptography suite to handle encryption/decryption, as well as file signing, verification and more. encryption-suite features a custom hashing library that implements SHA256, CSHAKE256, and KMACXOF256 algorithms. It is also able to encrypt/decrypt a given file or text input using DHIES encryption and Schnorr signatures with elliptic curves.

All of that encryption-suite can do is based on cryptographic algorthimic implementations are based of the National Institute of Standards and Technology's (NIST) specifications of the underlying Keccak algorithm and hashing algorithms based off of it. You can read about SHA-3 derived functions like cSHAKE and KMAC here from the NIST Special Publication archive directly!

encryption-suite is open source and can be found on my GitHub!
