NAME

       OAuth::Lite2::Signer - OAuth 2.0 signature (DEPRECATED)

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},
           );

DESCRIPTION

       This is for client to generate signed request, or for server to verify received request.

METHODS

   sign( %params )
       Returns the hash reference that includes parameters for OAuth 2.0 signed request.

           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},
           );

       secret
           Access token secret.

       algorithm
           The algorithm what you make signature with.

       method

       url URL of the request.

       debug_nonce
           Optional. If you omit this, nonce string is automatically generate random string.

       method
           HTTP method of the request.

       url URL of the request.

   verify( %params )
       Verify a signed request.

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

       signature
           'signature' parameter of the received request.

       secret
           The access token secret.

       algorithm
           'algorithm' parameter of the received request.
