This fork of /tdh2/tdh2easy provides a hybrid encryption scheme that uses Threshold Diffie-Hellman (TDH2) which is secure against adaptive chosen-ciphertext attacks (CCA2), combined with a modern symmetric stream cipher ChaCha20-Poly1305 instead of AES-256 in Galois/Counter Mode (GCM).

Please see README.md for additional info.
