Password Hash
Generate and verify password hashes with bcrypt, SHA and MD5 — entirely in your browser.
The hash is calculated entirely in your browser: the password never leaves this page.
Password hashing vs encryption
Hashing is a one-way transformation — you can verify a password matches a hash but cannot reverse the hash to get the original password. This is why good systems store hashes, not passwords.
Algorithm recommendations
- bcrypt — recommended for password storage (slow by design)
- SHA-256/512 — fast, not suitable for password storage alone
- MD5 — deprecated for security use
