3.1.  The SSHFP RDATA Format

   The RDATA for a SSHFP RR consists of an algorithm number, fingerprint
   type and the fingerprint of the public host key.

3.1.3.  Fingerprint

   The fingerprint is calculated over the public key blob as described
   in [7].

   The message-digest algorithm is presumed to produce an opaque octet
   string output, which is placed as-is in the RDATA fingerprint field.

3.2.  Presentation Format of the SSHFP RR

   The RDATA of the presentation format of the SSHFP resource record
   consists of two numbers (algorithm and fingerprint type) followed by
   the fingerprint itself, presented in hex, e.g.:

       host.example.  SSHFP 2 1 123456789abcdef67890123456789abcdef67890

   The use of mnemonics instead of numbers is not allowed.
