Bcrypt Hash Generator & Verifier
Generate secure bcrypt password hashes and verify passwords against hashes
Note: Bcrypt is a one-way hashing algorithm. You cannot "decrypt" a bcrypt hash back to the original password. You can only verify if a password matches a hash.

Higher values = more secure but slower. Recommended: 10-12

About Bcrypt
Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It's widely used for securely storing passwords.
Key Features
- One-way hashing: Cannot be reversed or decrypted
- Salted: Automatically includes a random salt
- Adjustable cost: Can be made slower as computers get faster
- Industry standard: Used by major applications worldwide
Hash Format
A bcrypt hash looks like this:
Format: $2a$[cost]$[22 character salt][31 character hash]
Privacy & Security
All hashing and verification happens locally in your browser. Your passwords never leave your device and are not sent to any server.
