Linux Containers provide a Free Software virtualization system for computers running GNU/Linux. This is accomplished through kernel level isolation. It allows one to run multiple virtual units simultaneously. Those units, similar to chroots, are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.

This is useful when you need the fingerprint to identify via TLS
Get the raw certificate:
echo Q | openssl s_client -connect mail.example.com:443 Copy and paste the scribble from —–BEGIN CERTIFICATE—– to —–END CERTIFICATE—– to a file called cert.pem. Including —–BEGIN CERTIFICATE—– as first and —–END CERTIFICATE—– as last line.
Generate the SHA1 fingerprint by issuing following command:
openssl x509 -in cert.pem -sha1 -noout -fingerprint
Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one.
ssh-keygen -t dsa ItemMake sure your .ssh dir is 700:
chmod 700 ~/.ssh Get your public ssh key on the server you want to login automatically.
scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com: Append the contents of your public key to the ~/.

Overview The following is an extremely simplified view of how SSL is implemented and what part the certificate plays in the entire process.
Normal web traffic is sent unencrypted over the Internet. That is, anyone with access to the right tools can snoop all of that traffic. Obviously, this can lead to problems, especially where security and privacy is necessary, such as in credit card data and bank transactions.
