Q: Is my data secure?
Yes. All processing happens entirely in your browser. No data is ever sent to any server.
Q: What does the rounds value mean?
Rounds (cost factor) determines the computational complexity. The actual number of iterations is 2^rounds. Higher values are more secure but slower. A value of 10-12 is recommended for most applications.
Q: Why is bcrypt better than MD5 or SHA for passwords?
Bcrypt is intentionally slow and includes a unique salt per hash, making it resistant to rainbow table and brute-force attacks. MD5 and SHA are designed to be fast, which makes them unsuitable for password hashing.
Q: Can I use this bcrypt hash in my application?
Yes. The generated hash follows the standard bcrypt format ($2b$) and is compatible with bcrypt libraries in Node.js, Python, Java, Go, and most other programming languages.
Q: How many rounds should I use?
For most web applications, 10-12 rounds provide a good balance between security and performance. Higher values (13-14) offer stronger protection but take noticeably longer to compute. Adjust based on your server capacity and security requirements.
