Digital signatures not working for RSA certificates with ECC signature algorithm

This is an identical problem my colleague posted back in June 2022 regarding Adobe on Windows but now also happening on macOS: 

It is a known bug inside Adobe Acrobat that was acknowledged and fixed by Adobe but only on Windows. This time we have also tried reaching out to Adobe contacts who managed to help us before but without any success.

We're currently in a pre-release stage with macOS token driver for our smart cards and this issue has resurfaced.

When trying to sign a pdf document with RSA key associated with a certificate whose signature algorithm is ECC Adobe returns the following error: “Error encountered while signing: The credential selected for signing is invalid”

Certificate in question is signed with a SHA384 ECDSA signature (sha384ECDSA).

After reviewing token driver logs we concluded that Adobe is requesting a X962 ECDSA signature with a RSA key which of course is not valid and is discarded from our token driver.

Considering all our smart cards containing RSA certificates have a ECC signature this is a major issue for us that renders our new token driver completely unusable for RSA cards while using Adobe products.

We have worked hard on providing our customers with a native system-wide solution for using smart-cards on macOS and this affects a huge amount of our customers and leaves us with no other option but to delay our token driver release until this is solved.

Hope someone at Adobe will see this and can reach out to me, we’re able to provide any kind of support with testing and development to solve this urgent issue.

Thanks!
