java-如何应用SHA-512？

在加密方面,我是newbee.我试图创建SHA-512将此变量数据转换为SHA-512,这样我就可以在项目中的服务器中传递它,我们将不胜感激.

if (pojo.getAmount() != null && !pojo.getAmount().equals("")) {

           //Data variables needs to convert in SHA-512
           hsString = merchantID + "" +  "" + req_id + "" + ip_address + ""
                   + notication_url + "" + package_name + "" + firstname + "" + lastname + ""
                   + middlename + "" + address1 + "" + address2 + "" + city + "" + state + ""
                   + country + "" + zip + "" + email + "" + phone + "" + client_ip + "" + ""
                   + cost + "" + currency + "" + secur3d + "" + merchantKey;

           //base64string one of the transaction parameters
            base64_enconded = Base64.encodeToString(hsString.getBytes(),Base64.DEFAULT);

解决方法:

您可以在Java中使用MessageDigest进行加密

描述-https://developer.android.com/reference/java/security/MessageDigest.html

支持的算法

> MD2
> MD5
> SHA-1
> SHA-256
> SHA-384
> SHA-512

试试这个代码

try{
        MessageDigest md = MessageDigest.getInstance("SHA-512");
        byte[] data = md.digest(hsString.getBytes());
        StringBuilder sb = new StringBuilder();
         for(int i=0;i<data.length;i++)
         {
            sb.append(Integer.toString((data[i] & 0xff) + 0x100, 16).substring(1));
         }
         System.out.println(sb);
     }
catch(Exception e)
     {
        System.out.println(e); 
     }
