Hello Quinn, @DTS Engineer I am willing to implement a driver to access a network based HSM (AWS KMS https://docs.aws.amazon.com/kms/latest/developerguide/concepts-intro.html) and delegate the signature operations to it (https://docs.aws.amazon.com/kms/latest/APIReference/API_Sign.html) I understand from the doc I must create my own implementation of CTKTokenDriver and tokens etc ... Is there any sample code I could use to help me geting started ?

Sorry my fault - it works :-)

This is not working with Xcode 14.1 and macOS 13

I just tested this on macOS 13 with Xcode 14.1 and it does not work :-(

Thank you @maikschulze - do you happen to remember the solution used by your colleague ? Or is it possible to ask him to post his/her solution here ?
