Hi, We've released version 4 of Triplesec, detailed at https://keybase.io/triplesec. Only differences are dropping the Twofish phase and switching from Keccak to the SHA3 standard. If you like, you can add support for encrypting and decrypting v4 ciphertexts to your library. Let me know if you have any questions about the spec.
I created a PHP 7.2+ version which supports the new v4 spec, but it has no tests (needed this for a personal project asap) and it's also not backwards compatible.
