Approach

General Strategy

1. Review Concepts: Studied foundational topics in cryptography (e.g., AES, RSA, hashing).
2. Break Down Challenges: Simplified each problem into smaller, manageable tasks.
3. Utilize Tools: Employed cryptographic libraries and tools for encryption and decryption (e.g., Python’s cryptography library).
4. Iterative Debugging: Tested solutions incrementally to validate each step.

Tools and Resources

• Programming Languages: Python and Bash.
• Cryptographic Libraries: OpenSSL, cryptography.
• Learning Materials: Module lectures, documentation, and online references.

Reflections

Key Insights

• Symmetric vs. Asymmetric Encryption: Grasped the practical applications of each approach.
• Importance of Hashing: Understood how hashing ensures data integrity and security.
• Key Management: Learned the critical role of secure key storage and handling.

Challenges Faced

• Complex Key Exchanges: Decoding how public and private keys work together required deeper exploration.
• Debugging Cryptographic Code: Identifying issues in encryption/decryption logic was often tricky but rewarding.

Update: Opening External Links in a New Tab

To enhance user experience, I’ve ensured that external links, such as pwn.college, now open in a new tab. This prevents users from unintentionally navigating away from the current page. Here’s how I implemented it:

Method

1. Manual Markdown Syntax:
   • For each external link, I added:

     {:target="_blank" rel="noopener noreferrer"}
     

   • Example:

     [pwn.college](https://pwn.college){:target="_blank" rel="noopener noreferrer"}
     

2. Optional Automation with Jekyll Plugin:
   • Created a custom plugin (_plugins/external_links.rb) to automatically add these attributes to external links.
   • See my guide on the implementation.
