Increase PBKDF2 iteration count in crypto.hash to 100,000 for stronger password hashing security.

[zeropath-ai-dev]

Summary

• The Vulnerability Description: The crypto.hash function used an insecurely low iteration count (5,000) with crypto.pbkdf2Sync for password hashing, making it vulnerable to brute-force attacks and not aligned with modern security best practices.
• This Fix: Increased the number of PBKDF2 iterations from 5,000 to 100,000, significantly strengthening resistance to password cracking attempts and meeting current key stretching recommendations.
• The Cause of the Issue: The original implementation set an insufficient iteration count in the password hashing algorithm, reducing computational cost for attackers.
• The Patch Implementation: Changed the third argument of crypto.pbkdf2Sync in crypto.js from 5,000 to 100,000, following current security guidelines for secure password storage.
