bcrypt Generator
Generate secure bcrypt hashes for your passwords
Higher values are more secure but take longer to compute. Recommended: 10-12
Why use bcrypt?
bcrypt is adaptive, meaning it can be made slower over time to resist brute-force attacks as computers get faster.
Cost Factor
The cost factor determines how much time is needed to calculate a single hash. Higher cost = more secure but slower.
How bcrypt Works
bcrypt combines the Blowfish encryption algorithm with adaptive hashing, automatically handling salt generation and incorporating the cost factor directly into the hash output.
bcrypt vs Other Algorithms
Unlike MD5 or SHA-1, bcrypt is specifically designed for password hashing with built-in protection against rainbow table attacks through salting and being computationally intensive.
Password Security Best Practices
Always use bcrypt with 10+ rounds, never store plain text passwords, and consider adding pepper (application-wide secret) for extra security beyond just salting.
bcrypt in Modern Applications
bcrypt is supported in most programming languages including Node.js, Python, PHP, Java, and Ruby. It remains a top recommendation by security experts for password storage in 2023.
The Importance of Salting
bcrypt automatically generates and manages unique salts for each password, preventing identical passwords from producing the same hash and protecting against rainbow table attacks.
Adaptive Nature of bcrypt
The cost factor makes bcrypt future-proof - as computers get faster, you can increase the rounds to maintain security without changing your hashing algorithm.
