SecureBlackbox 16: When I specify a Windows (or PKCS#11) certificate storage for signing, why do I get the following error: No signing certificate found?

Note: This article applies only to SecureBlackbox Legacy. For future development please consider using the latest version.

Please check that the storage is not empty; i.e., it contains at least one certificate with a private key.

You need a certificate with a private key to sign the data.
