When the Bcrypt Generator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Two identical passwords produced different hashes.
That is correct - Bcrypt embeds a fresh salt per hash, so identical inputs never share an output.
My login always fails after switching to Bcrypt.
Verify you are comparing with the password verify style check, not string equality against the full hash.
Hashing feels slow in my tests.
Bcrypt is deliberately slow - lower the cost factor for tests only and keep a higher value in production.
My hash field truncates the string.
Bcrypt hashes are long - store at least sixty characters so the salt and digest are not cut off.
I want to decrypt this hash back.
No - Bcrypt is one way, so verify a login attempt by hashing and comparing, never by reversing.
My database has old MD5 password rows.
Rehash on next successful login with Bcrypt, and force a reset for accounts that never sign in again.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Storing the plain password instead of the hash
- Reusing one hash across users
- Setting the cost factor too low
- Truncating the long hash string
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Why does the same password hash differently each time?
Bcrypt generates a new salt for every hash, so two runs over the same password correctly produce different strings.
What cost factor should I pick?
Ten is a common starting point - raise it until hashing takes a tolerable fraction of a second on your hardware.
Can I reverse a Bcrypt hash?
No - it is one way by design, so verification works by hashing the attempt and comparing, never by decrypting.
Does my password leave the browser?
Hashing runs locally for your session, and you should still avoid reusing a real password anywhere.
