Frequently Asked Questions

Does this tool decrypt bcrypt? +

No. Bcrypt is one-way. The tool checks whether the supplied candidate password matches the hash.

Why do bcrypt hashes look different for the same password? +

Bcrypt normally uses a random salt, so hashing the same password multiple times can produce different hashes that all verify correctly.

Should I enter a real production password? +

Avoid submitting sensitive production credentials to online tools. Use test values whenever possible.
