How-to articles, tricks, and solutions about SSL

To accept a server's self-signed SSL certificate in a Java client, you can create a custom javax.net.ssl.X509TrustManager and use it to override the default trust manager.

To import an existing X.509 certificate and private key into a Java keystore, you can use the keytool utility that is included with the Java Development Kit (JDK).

To perform HTTPS client certificate authentication in Java, you can use the HttpsURLConnection class and the SSLSocketFactory class.

This error message occurs when pip is unable to verify the certificate of the website it is trying to connect to.

Received fatal alert: handshake_failure is an error message that can occur during an SSL/TLS handshake.

To set up SSL on a local XAMPP/Apache server, you will need to generate a self-signed certificate, configure the Apache server to use the certificate, and then access the server using https.

To trust all certificates when using the Apache HttpClient library to make HTTPS requests, you can create a custom X509TrustManager implementation that trusts all certificates and use it to create an SSLContext with a custom TrustStrategy.

If you are getting the "unable to find valid certification path to requested target" error even after importing the certificate, there are a few possible causes and solutions:<br>

Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) protocol that allows a client to specify the hostname it is trying to connect to at the start of the handshaking process.

If you are getting a warning about an SSL connection when connecting to a MySQL database, it may be because you are using an older version of the MySQL client library that does not support SSL connections by default.
