Fix code scanning alert no. 18: Use of password hash with insufficient computational effort

[gitworkflows]

User description

Fixes https://github.com/khulnasoft/shipyard/security/code-scanning/18

To fix the problem, we need to replace the use of sha256 with a more secure password hashing algorithm, such as bcrypt. This will ensure that the hashed passwords are computationally intensive to crack, providing better security.

1. Import the bcrypt library.
2. Replace the makeSubHash function to use bcrypt for hashing the password.
3. Ensure that the bcrypt hash is truncated to the same length (14 characters) to maintain existing functionality.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Potential Compatibility Issue The change from sha256 to bcrypt might affect existing user passwords. Ensure there's a migration plan for existing hashed passwords. Performance Concern Bcrypt is intentionally slow for security, which might impact performance in high-volume scenarios. Consider the trade-off between security and performance.

Hey @gitworkflows - I've reviewed your changes - here's some feedback:

Overall Comments:

• Truncating the bcrypt hash to 14 characters may significantly reduce its security benefits. Consider redesigning the system to accommodate the full bcrypt hash.
• Please provide information on the migration strategy for existing hashed passwords and the potential performance impact of using bcrypt. Have you profiled the system with this change?

Here's what I looked at during the review

• 🟢 General issues: all looks good

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Security	Avoid truncating cryptographic hashes to maintain their security properties The makeSubHash function truncates the bcrypt hash to 14 characters, which significantly reduces its security. Consider using the full bcrypt hash or a more appropriate method for generating a fixed-length identifier. src/utils/CloudBackup.js [20] -const makeSubHash = (pass) => bcrypt.hashSync(pass, 10).slice(0, 14); +const makeSubHash = (pass) => bcrypt.hashSync(pass, 10); Apply this suggestion Suggestion importance[1-10]: 9 Why: Truncating a bcrypt hash significantly reduces its security, making this suggestion highly relevant. By recommending the use of the full hash, it addresses a critical security concern, ensuring the integrity and strength of the cryptographic operation.	9
Performance	Use asynchronous bcrypt hashing for improved performance and non-blocking operation Consider using an async version of bcrypt for better performance in a server environment. Replace bcrypt.hashSync with bcrypt.hash and make the function asynchronous. src/utils/CloudBackup.js [20] -const makeSubHash = (pass) => bcrypt.hashSync(pass, 10).slice(0, 14); +const makeSubHash = async (pass) => { + const hash = await bcrypt.hash(pass, 10); + return hash.slice(0, 14); +}; Apply this suggestion Suggestion importance[1-10]: 8 Why: This suggestion improves performance by making the hashing operation non-blocking, which is beneficial in server environments. It accurately modifies the code to use the asynchronous version of bcrypt, enhancing the application's responsiveness.	8
Enhancement	Implement error handling for decryption operations to improve robustness The decryptData function doesn't handle potential errors that may occur during decryption. Consider adding a try-catch block to handle decryption failures gracefully. src/utils/CloudBackup.js [17] -const decryptData = (data, password) => aes.decrypt(data, password).toString(Utf8); +const decryptData = (data, password) => { + try { + return aes.decrypt(data, password).toString(Utf8); + } catch (error) { + console.error('Decryption failed:', error); + throw new Error('Failed to decrypt data'); + } +}; Apply this suggestion Suggestion importance[1-10]: 7 Why: Adding error handling to the decryption function enhances the robustness of the application by managing potential decryption failures gracefully. This improvement increases the reliability of the code, although it does not address a critical issue.	7
