• 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 the number of days the certificate should be valid.
• 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 "Key Generation" as Enrollment Method if you want a certificate with the key generated on the server side.
  • Use "CSR" as Enrollment Method if you do not want the key generated on the server side. You will have to provide the CSR file via file upload or by pasting it into the text box.
• If you choose to provide 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 requested type and key size. Choose RSA-2048 if do not need a longer key and have tested that it works. Contact SUNET TCS if you need elliptic curve client certificates or RSA-8192).
  • The password used to encrypt the PKCS#12 file that will be generated.
  • As of 2023-05-24: For the time being, you must choose key protection algorithm Compatible TripleDES-SHA1 as the default alternative Secure AES256-SHA256 does not work.
• 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 "Key Generation", 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 "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
