Question

随着paypal的新变化，它开始抛出那些使用旧系统的SSL握手异常。＆＃34; PayPal SSL证书更改＆＃34; https://devblog.paypal.com/paypal-ssl-certificate-changes/

这可能对某人有所帮助。在我获得SSL握手异常后，我花了很多时间来解决它。

以下是例外：

javax.net.ssl.SSLHandshakeException：收到致命警报： handshake_failure

解决方案：

解决此问题的要求：

从1月19日开始，所有沙箱API端点都需要

 1.) Use TLS 1.2 and HTTP/1.1 connection

 2.) Upgrade to SHA-256 and use the G5 root certificate to make the HTTPS connection

第1点解决方案：

If you are using java 6 then better upgrade it to java 7

https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https

For my case i am using java 7 so TLSv1 (default) for JDK 7.

We have to enable it manually while starting server 

**-Dhttps.protocols=TLSv1.2** passed as vm argument.

第2点解决方案：

G5 cerificate import: Save it as test.cer

Go to java home/bin then run this command 

keytool -importcert   -file C:/test.cer

创建sanbox帐户。获取facilator密码并将签名作为参数传递

String encodedData = "USER=XXX-facilitator_api1.XXX.XXX"
                         + "&PWD=XXXXXXXXXXXX"
                         + "&SIGNATURE=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-"

                         + "&PAYMENTREQUEST_0_PAYMENTACTION=Authorization"

String responsepaypal = getHTMLcontent("https://api-3t.sandbox.paypal.com/nvp",encodedData ,"UTF-8");
String token = responsepaypal.toString().replaceAll("TOKEN=(.*?)&TIMESTAMP.*", "$1");//***Token for post request on paypal***

            DataOutputStream output = new DataOutputStream(con.getOutputStream());  
            output.writeBytes(urlParameters);
            output.close();

            DataInputStream input = new DataInputStream( con.getInputStream() ); 

            StringBuffer sb = new StringBuffer();

            String line;
            while ((line = input.readLine()) != null) {
                sb.append(line);
            }

            input.close(); 


            return sb.toString();
        }}
