Hash Toolkit
Generate secure hashes (bcrypt, Argon2, PBKDF2, scrypt), verify an existing hash, compute SHA-256/512 checksums with HMAC, and identify the algorithm of an unknown hash. All online, nothing stored.
Once your hash is generated, instantly convert it into an encrypted, single-use seecret link. Perfect for securely sharing your information without ever exposing it in an email, a message, or a screenshot.

Seecret.it: secure password hash generator
The Seecret.it password hash generator allows you to convert a password or text into a cryptographic hash using bcrypt, Argon2, PBKDF2, scrypt, WordPress and MD5. This tool is designed for developers, system administrators and cybersecurity professionals.
Hashing is a one-way process used to securely store passwords and verify data integrity. For modern applications, Seecret.it recommends bcrypt or Argon2id, while MD5 is provided for legacy or file verification purposes only.
No input or hash is stored. Everything is generated instantly. You can then securely share your hash using https://seecret.it/en, thanks to Seecret.it's encrypted, single-use link system.
