* It is *STRONGLY RECOMMENDED* that explicit representation of password argument
* to avoid ambiguity. For example string "6161" can mean a string "6161" or
* a hexadecimal string of "aa" (i.e. \x61\x61).
* @example
* mac = KJUR.crypto.Mac({'alg': 'hmacsha256'});
* // set password by implicit raw string
* mac.setPassword("\x65\x70\xb9\x0b");
* mac.setPassword("password");
* // set password by implicit hexadecimal string
* mac.setPassword("6570b90b");
* mac.setPassword("6570B90B");
* // set password by explicit raw string
* mac.setPassword({"rstr": "\x65\x70\xb9\x0b"});
* // set password by explicit hexadecimal string
* mac.setPassword({"hex": "6570b90b"});
* // set password by explicit utf8 string
* mac.setPassword({"utf8": "passwordパスワード");
* // set password by explicit Base64 string
* mac.setPassword({"b64": "Mb+c3f/=="});
* // set password by explicit Base64URL string
* mac.setPassword({"b64u": "Mb-c3f_"});
