For the time being there is no gui way of trusting a certificate in Chrome on Linux.
To trust a certificate/CA you must do the following:
1. Install certutil
sudo apt-get install libnss3-tools
2. Run certutil
certutil -d sql:$HOME/.pki/nssdb -A -t TC -n "domingo.dk" -i domingo.dk.crt
The certificate is inside the file called “domingo.dk.crt”.
#!/bin/sh # # usage: import-cert.sh remote.host.name [port] # REMHOST=$1 REMPORT=${2:-443} exec 6>&1 exec > $REMHOST echo | openssl s_client -connect ${REMHOST}:${REMPORT} 2>&1 |sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' certutil -d sql:$HOME/.pki/nssdb -A -t TC -n "$REMHOST" -i $REMHOST exec 1>&6 6>&-
Example:
./import-cert.sh domingo.dk
