+.SS "Fingerprints"
+The fingerprint is computed by hashing the binary representation of (the
+selected parts of) a key's data followed by the key type preceded by a
+single length octet, and the key's attributes, in lexicographic order of
+the attribute name. Each attribute consists of the attribute's name
+preceded by a single length octet, followed by the value preceded by a
+two-octet length. The lengths do not include themselves; neither string
+has a terminator character; there is no padding.
