Initialization of APS instance via wizard shows the following error during client certificate verification:

unable to load client cert: -8018 (SEC_ERROR_UNKNOWN_PKCS11_ERROR)"

Both certificate and a key are provided in correct form in corresponding input fields.


Private key was provided in encrypted form while APS application requires: "Private key must be unencrypted and not protected by password."


Decrypt the key by any available means. For example, openssl:

openssl rsa -in <Encrypted key filename>  -out <desired output file name>
