Free Online Security Tools
Generate strong credentials, verify checksums, and inspect tokens with security utilities that run entirely in your browser. Nothing you paste or upload ever leaves your device. Start with the Password Generator for fresh passwords or the Hash Generator to compute MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests on the fly.

Browse all toolsAre these online security tools safe to use?
Yes. Every Tool Matic security tool runs entirely in your browser. Inputs you paste or files you select are never uploaded to a server, so passwords, secrets, and tokens stay on your device.
Do Tool Matic security tools work offline?
Once a tool page has loaded, the cryptographic work runs locally without any further network calls. You can keep using the page in a flaky network or a fully offline browser tab.
What is the difference between hashing and encryption?
A hash is a one-way fingerprint of input data - useful for checksums and password storage but not reversible. Encryption is two-way and is used to protect data in transit or at rest. Use the Hash Generator for digests; choose an encryption tool when you need to recover the original value.
When should I use bcrypt instead of SHA-256?
Use bcrypt for storing user passwords because it is intentionally slow and salted, which resists brute-force attacks. Use SHA-256 (via the Hash Generator) for message integrity, file checksums, and content addressing where speed matters.
