How does Flask-Bcrypt perform in terms of speed and security?

Flask-Bcrypt is designed to provide secure password hashing using the bcrypt algorithm. In terms of speed, it is relatively fast for hashing, but the actual performance can depend on the cost factor you set, which determines the computational complexity.

What is the cost factor, and how does it affect performance?

The cost factor in bcrypt determines how many iterations of hashing are performed. A higher cost factor increases security but also slows down the hashing process. It's a trade-off between security and performance.

Is there a recommended cost factor for production use?

Yes, a common recommendation is to start with a cost factor of 12. However, you should test the performance on your specific hardware to find a balance that works for your application.

Can Flask-Bcrypt handle large volumes of password hashing?

Flask-Bcrypt can handle large volumes, but you should consider the performance impact of the cost factor and possibly implement asynchronous processing for better scalability.
