    I can confirm the same issue. After extended PKCS#11 library debugging we’ve come to a conclusion that as soon as key has type CKK_EC (or deprecated CKK_ECDSA) Adobe fails with “Unsupported Algorithm”.

    So from my understanding it is not even an algorithm issue but Adobe does not support CKK_EC key type at all while using PKCS#11 libraries.

    There is no way to resolve this, it is an unsupported key type which Adobe should implement.

    This is a critical issue for PKCS#11 users. It is unbelievable noone cares about this.
