 * Basic and Digest are the Http authorization standards but are not supported
 * by Mt Wilson.
 * 
 * The MtWilson scheme is similar to Digest but uses different parameters and
 * does not include a server-nonce.
 * 
 * Both PublicKey and X509 schemes use private/public key pairs. The X509
 * scheme differs from PublicKey in the way signatures are calculated (the
 * X509 specification includes the signature algorithm OID in the signature itself,
 * but regular private key signatures
 * do not add any OID's since OID's are specified by X509 not by RSA/DSA/etc.
