Do you support EC point multiplication: IE: I pass in an EC point, your system multiplies by the private key and replies? This is needed for custom protocols, like custom multisig, etc.

Hi! Nitrokey Pro and Nitrokey Storage use OpenPGP smart card - please take a look at their specification:

Nitrokey Start uses software implementation of OpenPGP v2.0 subset, with ECC. It could be modified to offer custom features.
