Security & Cryptography Tools
Passwords, hashes, and encoding.
Security & Cryptography Tools creates passwords, hashes and tokens — and then checks them. Build a strong credential with the Password Generator and grade it in the Password Strength Checker, produce file checksums with the MD5 or SHA-256 generators, hash a login with bcrypt, or encrypt a payload using AES. Every operation runs locally, so secrets never leave your device.
