How to deal with the authorities to verify the key pair?
Certification Services has a pair of public key and have a strong objection to allowing access to only the corresponding private key pairs. This way you just use some of the original private key to decrypt the encrypted information and other public key pair file. The possibility of fraud is minimized but not completely repaired as the brain of active conflict all the time.
