How does bcrypt verification work?
The checker reads the cost factor and salt from the encoded bcrypt hash, hashes the entered password and compares the result.

Frequently Asked Questions
Can a bcrypt hash be decrypted?
No. Bcrypt is a one-way password hashing algorithm. Verification works by hashing the entered password again.
Are the password and hash uploaded?
No. Both values are processed locally in your browser.
