About BCrypt
BCrypt is a password hashing function designed to be slow by design, making brute-force attacks impractical. The salt rounds (cost factor) controls how many times the algorithm iterates — each additional round doubles the computation time. Round 10 is the current industry standard; use 12+ for high-security applications.
Hash Format
$2b$10$[22-char-salt][31-char-hash]
$2b$— BCrypt version identifier$10$— Salt rounds (cost factor)- 22 chars — Random salt (base64 encoded)
- 31 chars — Hash result
