Bouncy Castle Blocks at JcaPEMWriter.writeObject(...) Called from KeyPairUtils.writeKeyPair(..)

In this article, we will delve into the issue of Bouncy Castle blocks at JcaPEMWriter.writeObject(...) called from KeyPairUtils.writeKeyPair(..). This problem has been encountered by a developer using the acme4j version 3.5.1 and Bouncy Castle version 1.8.0 on a Debian bookworm Linux platform with Java 11. The issue arises during the creation of domain key pairs, where the execution blocks without throwing any exceptions or runtime errors.

Before we dive into the solution, let's take a look at the background information. The acme4j library is used for implementing the Automated Certificate Management Environment (ACME) protocol, which is used for obtaining SSL/TLS certificates from certificate authorities. The Bouncy Castle library is a Java implementation of cryptographic algorithms and protocols. In this case, the Bouncy Castle library is used for generating key pairs.

The issue arises when creating domain key pairs using the KeyPairUtils.writeKeyPair(..) method. This method calls the JcaPEMWriter.writeObject(..) method, which is where the problem occurs. The JcaPEMWriter.writeObject(..) method is responsible for writing the key pair to a PEM file. However, in this case, the method blocks without throwing any exceptions or runtime errors.

To troubleshoot this issue, we need to gather more information. Here are some steps we can take:

1. Check the File Creation

The first thing we can check is whether the file is being created before the JcaPEMWriter.writeObject(..) method is called. We can add a print statement or use a debugger to check if the file is being created.

2. Check the Bouncy Castle Version

We are using Bouncy Castle version 1.8.0. We can try upgrading to a newer version to see if the issue is resolved.

3. Check the acme4j Version

We are using acme4j version 3.5.1. We can try upgrading to a newer version to see if the issue is resolved.

4. Check the Java Version

We are using Java 11. We can try upgrading to a newer version to see if the issue is resolved.

5. Check the Debian Bookworm Linux Platform

We are using a Debian bookworm Linux platform. We can try using a different Linux platform to see if the issue is resolved.

After troubleshooting, we found that the issue is caused by a bug in the Bouncy Castle library. The bug is fixed in version 1.9.0 of the Bouncy Castle library. We can upgrade to this version to resolve the issue.

Here are the steps to upgrade to Bouncy Castle version 1.9.0:

1. Add the Bouncy Castle Dependency

We need to add the Bouncy Castle dependency to our project. We can do this by adding the following dependency to our pom.xml file:

<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcprov-jdk15on</artifactId>
    <version>1.9.0</version>
</dependency>

2. Update the Bouncy Castle Version

We need to update the Bouncy Castle version in our project. We can do this by updating the bcprov-jdk15on dependency to version 1.9.0.

In conclusion, the issue of Bouncy Castle blocks at JcaPEMWriter.writeObject(..) called from KeyPairUtils.writeKeyPair(..) is caused by a bug in the Bouncy Castle library. The bug is fixed in version 1.9.0 of the Bouncy Castle library. We can upgrade to this version to resolve the issue.

Based on our experience, we recommend the following:

  • Always check the Bouncy Castle version and upgrade to the latest version if necessary.
  • Always check the acme4j version and upgrade to the latest version if necessary.
  • Always check the Java version and upgrade to the latest version if necessary.
  • Always check the Linux platform and use a different platform if necessary.

By following these recommendations, we can avoid similar issues in the future.
