ISSUE
When importing a PFX file into DualShield, it fails with the error "471:Invalid certificate or bad password"
CAUSE
The root cause of the error is that the PFX file is encrypted by AES-256-CBC which is not supported by the DualShield server with the framework versions older than Version 1.8.0.0906.
SOLUTIONS
There are 2 solutions.
The quickest solution is to import the PFX file to the Windows Cert store, export it using "TripleDES-SHA1", then upload it to DualShield.
The second solution is to upgrade the DualShield Framework to the latest version.
