How to sign for required parameter:

All parameters submitted by users except sign require signature.

First, sort signature strings in alphabetical order based on parameters (compare the first letter of all parameter, if they differ, then the string whose first letter comes earlier in the alphabet comes before the other string. If the first letters are the same, then the second letters are compared, and so on).

For example:Sign for the following parameter

apiKey=376892265asdad5d12726d8bbfbd8912b3&timeStamp=1510235730&nonce=309127&entrustSheetId=123456 and add application secretKey (only needs value, parameter and ‘&” is not required.)

For example:

secretKey=aQmE8U7bxj16KdJcSd3yX8F8Sakd8aO6LopnHXh27d4kWyb28PxcaTvGrajLDvAw

Signature string after splicing: apiKey=376892265asdad5d12726d8bbfbd8912b3&timeStamp=1510235730&nonce=309127&entrustSheetId=123456aQmE8U7bxj16KdJcSd3yX8F8Sakd8aO6LopnHXh27d4kWyb28PxcaTvGrajLDvAw

Note,"sign" is a required parameter.

Last,use md5 32bit algorithm to apply signature algorithm to the parameter, and then generate final signature string (the string assigns value to parameter ‘sign’).
