Bcrypt Hash & Verify
Passwort-Hashing
Hash a password
Verify a password
Bcrypt is intentionally slow. Each step up in cost roughly doubles the time. 10–12 is typical for web logins; 14+ for very high security.

Häufig gestellte Fragen
What cost should I use?
10-12 is typical for web logins. Higher = slower = more secure but worse UX.
Bcrypt vs Argon2?
Argon2 is the modern winner of the password hashing competition; bcrypt is older but still safe and widely supported.
