javax.net.ssl.SSLHandshakeException occurs. #33

Closed Daiki-Kawanuma closed 5 years ago

Daiki-Kawanuma commented 6 years ago

Since March 1, 2018, IBM Cloud invalidated TLS 1.0, TLS 1.1, and activated TLS 1.2 only. As a result, using this SDK with IBM Java, "javax.net.ssl.SSLHandshakeException" now occurs.

This is discussed at the following URL. https://issues.apache.org/jira/browse/HTTPCLIENT-1784

Is it possible to repair to explicitly use TLS 1.2?

This code works for me. IBM JDK: 1.8 WAS: 17.0.0.2 Liberty

SSLContext sslContext = SSLContexts.custom()
        .useProtocol("SSL_TLSv2")
        .build();

CloseableHttpClient httpclient = HttpClients.custom()
        .setSSLContext(sslContext)
        .build();

TLS1.2 included as part of latest release 1.5.0. Closing the issue.
