Verifying a certificate of a trusted remote host
Certificates issued by certification authorities have the signature of the
certification authority for you to check. Self-signed certificates only have the
signature of the host itself. This means that you must be very careful when
deciding to import (and thereby trust) the self-signed certificate of a remote host.
Trusted remote host certificate fingerprints
Certificate fingerprints are message digests calculated using the MD5 or SHA1
algorithms. The following procedure describes how to use a certificate fingerprint
to verify that you have the remote host’s actual certificate.
