Is there a way to check if some certificate is installed or at least list the installed certificates?
1 Answer
Look into /usr/share/ca-certificates
and sub-diretories.
The files you see there all have a crt
extension but they are in PEM format. If you want to inspect one of them (assuming you are in Nautilus) right-click on it and select open with View File
.
On the Command Line you would type openssl x509 -in <nameOfCertFile.crt> -noout -text
to see the complete certificate.
