Author: peter (src committer)
Date: Thu Nov 24 23:42:04 2016
New Revision: 49697
URL: https://svnweb.freebsd.org/changeset/doc/49697

Log:
  Add an experimental dynamic fingerprint display for some regularly updated
  ssl/tls certificates in use on the cluster.  This is a proof-of-concept and
  should not be referenced.

Added:
  head/en_US.ISO8859-1/htdocs/cgi/fingerprints.cgi   (contents, props changed)
