Password Hash Generator
Create password hashes instantly using bcrypt and popular hash algorithms, fully client-side.
Privacy-first: All hashing and verification are done in your browser. No data is ever sent to our servers.
Verify bcrypt hash
Check whether a password matches a bcrypt hash, fully client-side.
About this Password Hash Generator
This tool helps you generate hashes for testing and development. For real applications, store passwords using a slow hashing algorithm like bcrypt with an appropriate cost factor.
Common uses and guidance
bcrypt for password storage
Use bcrypt for storing passwords because it is intentionally slow and more resistant to brute-force attacks.
SHA and MD5 for checksums
SHA-256/SHA-512 and MD5 are fast hashes. Use them for integrity checks, not for storing passwords.
Verify bcrypt safely
Paste a bcrypt hash and test a password match locally in your browser without sending data anywhere.
How It Works
1. Enter input
Type the password (or text) you want to hash. Everything stays on your device.
2. Choose an algorithm
Select bcrypt for password storage, or SHA/MD5 for checksum-style hashing.
3. Generate and copy
Generate the hash instantly, then copy it for testing, development, or verification.
Perfect For
Developers and QA
Generate sample hashes for unit tests, fixtures, and development workflows.
Security reviews
Quickly compare algorithms and understand why bcrypt is recommended for passwords.
Education and training
Learn hashing basics and practice verifying bcrypt hashes in a safe environment.
Best Practices
Prefer bcrypt for passwords
Avoid storing passwords with SHA/MD5. Use bcrypt with an appropriate cost factor.
Use unique passwords
Never reuse passwords across sites. Unique passwords reduce the impact of breaches.
Use a password manager
Store strong, unique passwords securely and generate them when needed.
