Add permanent SSL certificate exception in Chrome (Linux)

Solution 1:

This is a summary of the answers from the thread
Disable Google Chrome warning if security certificate is not trusted.

You can avoid the message for trusted sites by installing the certificate.
This can be done by clicking on the warning icon in the address bar, then click
Certificate Information -> Details Tab -> Export...
Save the certificate.

Use Chrome's Preferences -> Under The Hood -> Manage Certificates -> Import.
On the "Certificate Store" screen of the import, choose "Place all certificates in the following store" and browse for "Trusted Root Certification Authorities." Restart Chrome.

Solution 2:

Using Chrome Version 23.0.1271.97 on Linux:

First click on the certificate warning and export the certificate to your file system. (Connection > Certificate Information > Details > Export)

Then use certutil in order to add this saved certificate as a trusted peer:

certutil -d sql:$HOME/.pki/nssdb -A -t P -n <certificate nickname> -i <certificate filename>

Restart Chrome and you're done.

Solution 3:

The only way I got it working in Chromium with Ubuntu Linux is using this certutil commandline:

certutil -d sql:$HOME/.pki/nssdb -A -t "CP,CP," -n CertNickName -i cert_file.crt

Solution 4:

Please have a look at this thread:
Can't convince Chrome that my Tivo's self signed certificate is ok.

The article remarks that:

You need to specify the "C,," trust flags to work around the NSS bug.

If this thread does relate to your problem, it looks like this is a known bug in Chrome, where the "P,," trust flags is not working: libpkix ignores the P (trusted peer) trust flag

I hope this helps (I'm answering a bit blindly, since I'm not on Linux).

Solution 5:

Google Chrome in Linux doesn’t have a SSL certificate manager, it relies on the NSS Shared DB. In order to add SSL certificates to the database you will have to use the command line. I will explain how you can add the CAcert certificates and a very easy way to add self-signed certificates.
