The package org is not accessible when importing org.bouncycastle

Question

I am encountering an issue when trying to import the Bouncy Castle library in my Java project. Despite adding the Bouncy Castle library to my project, I'm receiving the error message "The package org is not accessible" when attempting to import specific classes from the library.

import org.bouncycastle.cert.*;
import org.bouncycastle.asn1.x500.X500Name;
import org.bouncycastle.asn1.x509.BasicConstraints;
import org.bouncycastle.asn1.x509.KeyUsage;

Steps I've taken:

1. Verified Bouncy Castle Library: I have downloaded the Bouncy Castle JAR file and added it to my project's classpath.

2. Checked for Library Compatibility: I have added the correct version of the Bouncy Castle library that should be compatible with my project.

3. Confirmed Build Path Configuration: I have properly configured the Bouncy Castle library in my project's build path and marked it as a dependency.

4. Checked IDE Specific Configuration: I am using [insert your IDE name] and have followed the necessary steps to configure the library. However, the issue persists.

5. Cleaned and Rebuilt: I have tried cleaning my project and rebuilding it, but it did not resolve the problem.
