SYNOPSIS

           my $signed_params = OAuth::Lite2::Signer->sign(
               secret    => q{my_token_secret},
               algorithm => q{hmac-sha256},
               method    => q{GET},
               url       => q{http://example.org/protected/resource},

               algorithm => q{hmac-sha256},
               method    => q{GET},

           );

   verify( %params )
       Verify a signed request.

           unless ( OAuth::Lite2::Signer->verify( %params ) ) {
               $app->error("Invalid request");
           }

       signature
           'signature' parameter of the received request.
