ed25519 keys are always 32-byte. 64-byte representations are (secret key + public key) concatenated.

trying to use your lib for DH on the cardano blockchain, and that concated 64 byte private key is not secret key + public key in that case.

The extended keys are following this specification:

This is not a library for Cardano blockchain. This is library for generic ed25519 keys. Cardano uses custom implementation on top of this.
