Certificate signing requests are described in PKCS#10 standard. They are used to supply a Certification Authority with the needed information to issue a valid certificate for you without knowing your private key. This includes your personal information and your public key.
Netscape SPKAC files can not be created or exported, but they can be imported and signed. This requests are marked in the Signature field as SPKAC and they do carry a netscape icon.
After clicking on the New Request
button the Certificate Wizard will be started to ask
all needed information for generating a new Request. See:
Wizard
The request generation can also be invoked by the context menu of a certificate (Export->Request).
This menu point is only available if the private key of the certificate is available.
In this case all needed data is copied from the certificate and the Wizard is not invoked.
Requests can be exported only by the context-menu. There is a sub-menu to select PEM or DER format. The filename can be selected in the next dialog.
All information contained in the request are shown. If the Keystore does contain
the private key corresponding to the request the keys internal name is shown in the
Key
field.
