+ <p>Calculates a ssh fingerprint from a public host key as openssh does.</p>
+ <p>The algorithm in <c>ssh_hostkey_fingerprint/1</c> is md5 to be compatible with older
+ ssh-keygen commands. The string from the second variant is prepended by the algorithm name
+ in uppercase as in newer ssh-keygen commands.</p>
