const char * jwt_alg_str ( jwt_alg_t alg )

Convert alg type to it's string representation.

Returns a string that matches the alg type provided.

Parameters

alg	A valid jwt_alg_t specifier.

Returns: Returns a string (e.g. "RS256") matching the alg or NULL for invalid alg.

jwt_alg_t jwt_get_alg ( const jwt_t * jwt )

Get the jwt_alg_t set for this JWT object.

Returns the jwt_alg_t type for this JWT object.

Parameters

jwt	Pointer to a JWT object.

jwt_alg_t jwt_str_alg ( const char * alg )

Convert alg string to type.

Returns an alg type based on the string representation.

Parameters

alg	A valid string for algorithm type (e.g. "RS256").

Returns: Returns a jwt_alg_t matching the string or JWT_ALG_INVAL if no matches were found.
