• Go to https://cert-manager.com/customer/sunet/idp/clientgeant, select your organization's IdP and login there.
• Select the right certificate profile:
  • Use "GÉANT Personal Certificate" for normal client certificate for email signing etc outside of the grid/IGTF world.
  • Use "GÉANT IGTF-MICS Personal" for a grid/IGTF personal (client) certificate for normal use
  • Use "GÉANT IGTF-MICS-Robot Personal" for a grid/IGTD robot personal certificate (seldom used)
    
• Select if you want the key generated on the server side or locally. While the former is more convenient, there may be policy reasons or technical reasons for not using that:
  • Use "Generate RSA" if you want a certificate with the key generated on the server side.
  • Use "Generate ECC" only if you are testing ECC certificates. If unsure, use RSA.
  • Use "Upload CSR" and choose the CSR file you have generated if you do not want the key generated on the server side.
• If you choose to upload the CSR, you must first have created your key and CSR locally, using whatever software you use for that. With OpenSSL, that could be:
  
  

  openssl req -new -newkey rsa:2048 -out usercert_request.pem -keyout userkey.pem -subj '/CN=Mitt Namn'
  chmod go= userkey.pem
  cat usercert_request.pem

• If you choose to generate the certificate on the server side, you must provide the password used to encrypt the PKCS#12 file that will be generated.
• Click "Submit" and accept the click-through license.
• After a short while, you will get to dowload your certificate. The format depends on your choice above:
  • With "Generate RSA/ECC", you will get a PKCS#12 file called certs.p12 containing key and certificate. You can import that in your browser using "Import Certificate" or similar.
  • With "Upload CSR", you will get a PEM-formatted certs.pem containing just the certificate. If you need it in your web browser, you need to create a PKCS#12 file yourself. With OpenSSL as above, that could be:
    
    

    openssl pkcs12 -export -inkey userkey.pem -in certs.pem -out certs.p12
    

• If you get the error message "Sectigo Certificate Manager enrollment request failed. Please contact your security administrator." when you have clicked the submit button and accepted the click-through license, it may be because you have hit the limit of two valid certificates per identity and certificate profile. You need to revoke at least one of the two certificate before another one can be issued. 2020-04-27: This behaviour will be reported as a bug to Sectigo to ask them to handle this in a smoother way.
