Bcrypt Generator & Verifier
What is Bcrypt?
Bcrypt is a password-hashing function designed for security. Unlike fast hash functions (MD5, SHA-1), bcrypt is intentionally slow via a configurable cost factor — making brute-force attacks impractical. Each hash includes a random salt, so identical passwords produce different hashes. The cost factor (rounds) doubles the computation time for each increment: cost 10 takes ~100ms, cost 12 takes ~400ms, cost 14 takes ~1.5s. Never store plain-text passwords — always hash them with bcrypt or a similar adaptive function.
How to Use the Bcrypt Generator
-
Enter your password in the 'Hash' tab and choose a cost factor (10–12 is recommended for most apps).
-
Click 'Generate Hash' — the bcrypt hash appears below and is ready to store in your database.
-
To verify a password against an existing hash, switch to the 'Verify' tab.
-
Enter the plain-text password and the stored bcrypt hash, then click 'Verify'.
-
A green checkmark confirms a match; red means the password is wrong.
