NewProvisioningSession expects pkcs8 private key and SHA race fix

Fix SHA hashing to remove race condition. This change
fixes the implementation by passing in the digest buffer.

-------------
The input to ProvisioningEngine::NewProvisioningSession should be
pkcs8 private key instead of pkcs1 private key
