    Bertrand WILLIAMSRIOUX thanks for the great demo. Could you share the link to the code of your demo? Maybe I can help with the current issue of the private key that is still stored on the node server to create the blockchain gate.
    Thanks,
    Robin

    Hi Robin

    The code was published to the sign transactions offline task

    Here it is https://github.com/brioux/fabric-client-signer

    I stoped working on this since it was closed by Si, and we decided to move on to integrating the HsmX509Provider class for key management, and possibly using cloud HSM hosting (e.g. Vault). See this new issue with Pritam Singh.

    I am still curious how to go about setting up a fabric gateway that support complete offline signing, not using a standard X.509 identity.

    I was thinking, the client should be able to provide a signature (linked to is public key) to open a gateway connection request (without exposing the private key). There was not much documentation on this (that i could find). We decided to pursue the other track, since fabric supports HSM.X509 and PKCS11, which, is more secure and easier to build than my custom solution.
