SSH Key Fingerprint

Generates a fingerprint for an SSH key.

Download Chilkat Ruby Library

require 'chilkat'


key = Chilkat::CkSshKey.new()

#  Load an SSH key from an encrypted OpenSSH-formatted private key:
key.put_Password("secret")

#  First load the PEM into a string:
keyStr = key.loadText("privkey_openssh_encrypted.pem")

#  Import into the SSH key object:
success = key.FromOpenSshPrivateKey(keyStr)
if (success != true)
    print key.lastErrorText() + "\n"
    exit
end

#  Generate the fingerprint:

fingerprint = key.genFingerprint()

print fingerprint + "\n";

#  A sample fingerpring looks like this:
#  ssh-dss 2048 d0:5f:f7:d6:49:60:7b:50:19:f4:41:59:d4:1f:61:7a
