KeyManager is a stand alone PKI tool for key generation and certificate enrollment. The KeyManager tool is packaged as chrome based Firefox extension. We have extended the Certificate Manager wizard in Mozilla PSM and added the capability for key generation and SCEP based certificate enrollment. Currently, PSM allows import and export of keys but does not provide interface for local key generation.
In addition, the tool supports signing of proxy certificates for delegation of authorities and provides XUL based GUI for signing archive files.
