How to convert GnuPG Key to MultiChain Priv & Pub Key

Question

Hi, Multichain Team,

First thanks for the project.

Would like to know if it is possible to convert GnuPG bi-Keys to MultiChain key? And if Yes, how can we do that?

Second question, if any, do MultiChain keys be stored in HSM token ? Does MultiChain support PKCS11 ?

Thanks in advance for your answers.

Best Regards.

MultiChain uses the same ECDSA cryptography scheme as bitcoin and bitcoin-derived blockchains, so I don't think it's possible to convert GnuPG keys to MultiChain directly.

Note however that in many cases it's possible to securely associate a non-ECDSA public key with a blockchain addresses by publishing the public key from that address onto a stream. Other nodes can then use liststreampublisheritems to retrieve the non-ECDSA public key for that address from the stream.

As for HSM, any HSM module that is compatible with bitcoin should be easily modifiable to work with MultiChain, since both the cryptography and transaction formats are identical.
