Renewing a user certificate
Note
Only renew valid certificates
You cannot renew a certificate that has already expired. If you attempt to
renew an expired
certificate, the certificate authority will reject the request. When a certificate has already
expired, instead of renewing the existing certificate, you need to request a new certificate.
With the "Renew" button, you can when necessary, e.g. with compromised certificates,
generate a new certificate.
To do this, enter the corresponding password. The serial number is automatically
incremented by one.
