Added Certificate Ripper

[Hakky54]

Certificate ripper extracts server certifcates including the full chain into a der, p7b, pkcs12 or pem file. It makes it easy to update/maintain truststores or for analysing certificates.

Example usage:

Add the dependency

<dependency>
    <groupId>io.github.hakky54</groupId>
    <artifactId>certificate-ripper</artifactId>
    <version>2.7.1</version>
</dependency>

Run the code snippet

public class App {
 
     public static void main(String[] args) {
         CertificateRipper.exportToPem("https://github.com")
                 .withIncludeHeader(false)
                 .withCombined(true)
                 .withDestination("/path/to/export/github-chain.crt")
                 .build()
                 .run();
     }
 
 }
