SessionCreateSignatureFromKeyId Method

Create a signature configuration based on the private key's ID and an external certificate

Create a signature configuration where only the private key is contained in the PKCS#11 device and the signing certificate is provided externally. This is intended for PKCS#11 devices that can only store private keys, e.g. the Google Cloud Key Management (KMS).

The private key object is identified using its ID, i.e. the CKA_ID object attribute in the PKCS#11 store.

The certificates of the trust chain should be added using AddCertificate(Stream).
