About Bcrypt
What is Bcrypt?
Bcrypt is a password hashing function designed by Niels Provos and David Mazières. It's based on the Blowfish cipher and incorporates a salt to protect against rainbow table attacks. The algorithm is intentionally slow to make brute-force attacks impractical.
Key Features
- Adaptive function - can be made slower as computers get faster
- Incorporates a salt to prevent rainbow table attacks
- Intentionally slow to resist brute-force attacks
- Industry standard for password hashing
- One-way function - cannot be reversed
Generate bcrypt hashes for secure password storage. Bcrypt is designed specifically for hashing passwords with built-in salt and configurable work factor (cost). It's intentionally slow to resist brute-force attacks, making it the industry standard for password hashing.
Key Features
- ✓Generate bcrypt password hashes
- ✓Configurable cost factor (salt rounds)
- ✓Built-in random salt generation
- ✓Verify passwords against bcrypt hashes
- ✓Industry-standard password hashing
How to Bcrypt Hash Generator
- 1
Enter password
