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
