If you have a CSR at hand, navigate to Submit CSR in the SCEPman Certificate Master top menu. You can copy and paste the CSR in PEM format (i.e. text) into the text box, or drag and drop the CSR file in binary or PEM format into the grey area at the bottom. You may use the Browse link as well to select a CSR file in binary and PEM format. When using the text box, you have to hit the Submit button afterward to issue the certificate, while uploading a CSR file immediately issues the certificate. Your browser will download the certificate in DER-encoded format.
