How to install .cer certificate authority in Ubuntu Linux?

Question

linux

Good afternoon
There is a certificate .cer

-----BEGIN CERTIFICATE-----
XUZ123.........
-----END CERTIFICATE-----

How to set it as a certificate authority?

Answer 1

Mmmm... make it trusted root? If so, then:
- copy to /etc/ssl/certs (or wherever openssl wants - looks in the openssl build parameters)
- create a link to this file with a specific name, which is formed like this:

ln -s filename.cer `openssl x509 -hash -noout -in filename.cer`.0

If a file with the same name already exists, create a file .1, .2, and so on.
