Signature process

• Combine message parameter All parameter must be by ASCII sequential order, except sign and body. Take the “ parameter number 1 = parameter value 1, parameter number 2 = parameter value 2” to connect all parameters.

• Combine mwMacKey Sign in KEY will place to the last parameter with agreed key “KEY=xxxxx”. Before downloadKey，we do not have mwMacKey，so we use assigned key when invoke downloadKey. Before signin，we do not have mwMacKey，so we use mwTmk when invoke signin.

• Signature Sign in value calculate per MD5-32 encryption and then converted to HEX in capital letter, named Sign-in value, as sign parameter.

• PS when parameter value is null or blank, the parameter is not required to stated
