加签

注意: 空字符串也参与签名

【商户加签】  商户使用 "商户自己的RSA私钥" 对请求报文进行加签
待签名串 = ASCII升序(reqHeader) + MD5大写(ASCII升序(reqBody))
reqSign = RSA私钥加签(待签名串, 商户私钥)

对报文中的请求头reqHeader和请求体reqBody，按照名称的ASCII码从小到大先分别进行排序，如果名称的首字母相同，则比较第二个字母，以此类推。

将排序后的reqBody计算Md5(hex转大写)，再将排序后的请求头reqHeader和请求体reqBody计算得到的Md5值进行拼接，拼接后的字符串使用RSA2私钥签名（公私钥由商户自己生成，密钥位数为2048（SHA256WITHRSA）位【其他算法使用其他算法的密钥和加密方式】，私钥商户自己保存，公钥提供给易生验签），得到签名串reqSign。

验签



【商户验签】  商户使用 "易生的RSA公钥" 对易生的响应报文 进行验签
待签名串 = ASCII排序(rspHeader) + MD5大写(ASCII排序(rspBody))
验签结果 = RSA公钥验签(待签名串, rspSign, 易生公钥)

商户/代理方用以验证返回的报文是否合法。

对返回报文中的返回头rspHeader和返回体rspBody，按照名称的ASCII码从小到大先分别进行排序，如果名称的首字母相同，则比较第二个字母，以此类推。将排序后的rspBody计算Md5(hex转大写)，再将排序后的请求头rspHeader和请求体rspBody计算得到的Md5值进行拼接，拼接后的字符串，返回报文中rspSign签名，使用RSA公钥验签（公钥由易生提供，密钥位数为2048（SHA256WITHRSA）位【其他算法使用其他算法的密钥和加密方式】，计算签名是否正确用以确认易生签发的报文数据。

注意

若rspBody没有返回则算MD5的时候用 {}
