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
