The HMAC-SHA224 signature method uses the HMAC-SHA224 signature algorithm as defined in [RFC6234] where the Signature Base String is the text and the key is the concatenated values (each first encoded per Parameter Encoding) of the Consumer Secret and Token Secret, separated by an '&' character (ASCII code 38) even if empty.

Member Function Documentation

build_signature()

string ceLTIc\LTI\OAuth\OAuthSignatureMethod_HMAC_SHA224::build_signature	(	OAuthRequest	$request,
		OAuthConsumer	$consumer,
		?OAuthToken	$token )

Build up the signature.

NOTE: The output of this function MUST NOT be urlencoded. the encoding is handled in OAuthRequest when the final request is serialized

Parameters

OAuthRequest	$request	Request
OAuthConsumer	$consumer	Consumer
OAuthToken	$token	Token

Returns

string

Reimplemented from ceLTIc\LTI\OAuth\OAuthSignatureMethod.

get_name()

ceLTIc\LTI\OAuth\OAuthSignatureMethod_HMAC_SHA224::get_name

(

)

Name of the Signature Method.

Returns

string

Reimplemented from ceLTIc\LTI\OAuth\OAuthSignatureMethod.
