   (1 octet of class, 1 octet of algid, 20 octets of fingerprint)

   Authorizes the specified key to issue revocation signatures for this
   key.  Class octet must have bit 0x80 set, other bits are for future
   expansion to other kinds of signature authorizations. This is found
   on a self-signature.

   Authorizes the specified key to issue revocation signatures for this
   key.  Class octet must have bit 0x80 set. If the bit 0x40 is set,
   then this means that the revocation information is sensitive.
   Other  bits are for future expansion to other kinds of authorizations.
   This is found on a self-signature.
