Security Tools

IP, hash, URL, password, subnet, CVSS, Base64/Hex, JWT, and regex — all in your browser.

Check any IP address against 70+ security vendors via VirusTotal.

Paste an MD5, SHA-1, or SHA-256 hash to check it against 70+ security vendors via VirusTotal.

Submit a URL to check its reputation against 70+ vendors. Unknown URLs are submitted for scanning automatically.

Check if a password has appeared in a known data breach. Uses k-anonymity — only the first 5 characters of a SHA-1 hash are sent. Your password never leaves your browser.

Calculate subnet details from a CIDR range — network address, broadcast, host range, mask, and wildcard.

Calculate a CVSS v3.1 base score. Select a value for each metric — the score updates automatically.

Encode and decode text using Base64, hexadecimal, or URL encoding — all processed locally in your browser.

Decode a JSON Web Token (JWT) to inspect the header and payload. The signature is not verified — everything runs in your browser.

Test a regular expression against a string. Matches are highlighted inline and listed below.
