Step-by-step instructions
- Paste the password in the first block.
- Optionally add a blank line and bcrypt rounds (4-15) in the second block.
- Click Transform to generate the bcrypt hash.
Common use cases
- Debugging request payloads and encoded values quickly.
- Generating development data and identifiers.
- Validating text, URLs, timestamps, and structured content.
Useful for auth testing and migrations when you need bcrypt hashes generated quickly with controlled rounds.
Common mistakes to avoid
- Using very low rounds in production-like environments.
- Assuming bcrypt output is deterministic for the same password.
- Pasting rounds in the first block instead of the optional second block.
