Password Hashing Not Secure Enough

Passwords are hashed but using a weak algorithm. Plain MD5, SHA-1, or simple salted SHA-256 is used instead of proper password hashing. Security audit flags the implementation as inadequate for protecting user credentials.

Password storage exists but doesn't use modern algorithms that resist brute-force attacks.

Error Messages You Might See

Security audit: weak password hashing Password algorithm not sufficient MD5 hashing detected (insecure)
Security audit: weak password hashingPassword algorithm not sufficientMD5 hashing detected (insecure)

Common Causes

  1. Using non-password-specific algorithm: SHA-256, SHA-512 are too fast for passwords
  2. Insufficient salt or no salt at all
  3. Hash function not iterated: bcrypt, argon2 are intentionally slow
  4. Key derivation instead of password hash: PBKDF2 acceptable but bcrypt/argon2 better
  5. No pepper (application secret) combined with salt

How to Fix It

Use bcrypt (industry standard) or argon2 (newer, stronger). Never use: MD5, SHA-1, SHA-256 alone. Library handles salt and iteration automatically. Example: bcrypt.hash(password, 10) - 10 is cost factor. Verify: bcrypt.compare(password, hash). If migrating: rehash on next login, don't bulk convert.

I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti. I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks. https://blog.vtemian.com/ Yovel Cohen Yovel Cohen I got a lot of experience in building Long-horizon AI Agents in production, Backend apps that scale to millions of users and frontend knowledge as well.

Frequently Asked Questions

Why is bcrypt better than SHA-256?

bcrypt is slow by design (intentional CPU cost). SHA-256 is fast (designed for checksums). Slow = expensive for attackers trying brute force.

How to use bcrypt?

Hash: bcrypt.hash(password, 10). Verify: bcrypt.compare(password, hash) returns true/false. 10 is cost (higher = slower).

How to migrate from weak hashing?

Don't bulk upgrade. On next login, verify old hash, then rehash with bcrypt and store new hash. Old hashes deleted eventually.
