#
+# there are many ways to represent an SSH key, since SSH keys can be of
+# a variety of types.
+#
+# To confuse matters more, there are multiple binary representations.
+# So, for example, an RSA key has a native SSH representation

+#
+# AWS uses fingerprints of the DER representation, but SSH typically reports
+# fingerprints of the SSH representation.
+#
+# Also, SSH public key files are base64 encoded, but with whitespace removed
