Generate password hashes with bcrypt algorithm
Cost factor determines the computational cost. Higher values are more secure but slower. Recommended: 10-12
Bcrypt is a cryptographic hashing algorithm, recommended for password hashing. It's designed to be slow and computationally expensive, making it resistant to brute-force attacks. Bcrypt automatically handles salt generation and includes the cost factor in the hash output.
Password hashing is a one-way process of securing plain text password by creating a bit string of a fixed size called hash using cryptographic hash function. Cryptographic hash functions are designed to be a one-way function, that is, a function which is infeasible to invert.
Password Hashing Competition, organized by cryptography and security experts, is an open competition to raise awareness of the need of strong password hashing algorithms and to identify hash functions that can be recognized as a recommended standard. Bcrypt was selected as the final PHC winner on 20 July 2015.
The cost factor (also called rounds) determines how many iterations the algorithm will perform. Higher values are more secure but take longer to compute. For most applications, a cost factor of 10-12 is recommended. Cost factor 10 takes about 100ms on modern hardware, while cost factor 12 takes about 400ms. For production systems, start with 10 and increase if needed based on your performance requirements.
No, we do not store any passwords. All hashing and verification is performed in real-time and no data is saved or transmitted to third parties.
MD5, SHA-1, and SHA-256 are fast hashing algorithms designed for data integrity, not password security. They are vulnerable to brute-force attacks because they can be computed quickly. Bcrypt is specifically designed for password hashing because it's slow and computationally expensive, making brute-force attacks impractical. Always use trusted libraries like bcrypt for password hashing.
