🚨 Severity: HIGH 💡 Vulnerability: The codebase included active, though deprecated, methods for RC4 encryption (`Crypto.encryptRC4` and `Crypto.decryptRC4`). RC4 is a weak cryptographic algorithm with known vulnerabilities, making any data encrypted with it susceptible to being broken. 🎯 Impact: If a developer accidentally used these deprecated methods, they would be implementing weak, insecure encryption, putting sensitive data at risk of exposure. 🔧 Fix: The `encryptRC4` and `decryptRC4` methods in `Crypto.java` have been modified to throw a `CryptoException` upon being called. This effectively disables the algorithm and prevents its use, forcing a migration to more secure alternatives like AES. ✅ Verification: The build passes successfully, and the updated tests in `RC4Test.java` confirm that calling the RC4 methods now correctly throws a `CryptoException`.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
This change disables the insecure RC4 encryption algorithm by modifying the
encryptRC4anddecryptRC4methods to throw aCryptoException. This prevents the use of the weak algorithm and improves the overall security of the library. The associated tests have been updated to reflect this change, and build artifacts have been removed and added to the.gitignorefile.PR created automatically by Jules for task 7017059584308421613 started by @richkmeli
