nCipher MSCAPI CSP Install Wizard support software weak key generation

mscapi-csp-key-generation (9076) The risk level is classified as LowLow Risk


The Install Wizard in nCipher MSCAPI CSP key generator running on Windows 2000 systems causes incorrect keys to be generated. If a user selects cardset protection in the Installation Wizard without creating a new Operator Card Set, keys would be generated to use module protection instead of Operator card protection. This vulnerability could result in weaker than anticipated security on the system.
