Our company was having trouble with our connection to Authnet in the sandbox environment due to the recent upgrade requiring TLS 1.2. Our company's app is running with Java 1.7. We tried setting our project's http protocols to force TLS 1.2 but this didnt seem to be working. Eventually we discovered that the anet-java-sdk:1.9.3 is usign a default HTTPClient. We had to override the HttpClient and HttpCallTask classes in the util directory. Anywhere that the class set up a defaultHttpClient, we replaced that code with this: SSLContext sslContext = SSLContexts.custom() .useTLS() .build(); SSLConnectionSocketFactory f = new SSLConnectionSocketFactory( sslContext, new String[]{"TLSv1.2"}, null, SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER); CloseableHttpClient httpClient = HttpClients.custom() .setSSLSocketFactory(f) .build(); The entire HttpClient and HttpCallTask classes are below. If we could get these changes added to a new SDK from Authnet, that may help other customers avoid this same problem. Also, it would be helpful for us as then we can continue just importing the entire file library rather than including all the anet files in our own code structure.
