Thank you, I was able to create CTK extension and display my HSM certificates. However, I am unable to get pin window displayed, when I try to sign something with my HSM certificate. Documentation says: responding with TKErrorCodeAuthenticationNeeded will trigger user authentication after which the current operation will be re-attempted. I respond with this code, and still nothing. There is also mentioned TKTokenOperationConstraint. How do I set that? Thank you.

Hi, Thank your for the reply. I was able to create CTK extension for HSM tokens. I have one last problem. Apple documentation says if We throw error with error code "TKError.Code.authenticationNeeded.rawValue" will trigger user authentication (in tokenSession for data signing). However, passwords window does not appear. I found out, that I have to set TKTokenOperationConstraint. Where should I set it? Thank you.
