All tools.

AES-256-GCM encryption in the browser. Passphrase-protected via PBKDF2 (600 000 iterations), authenticated and tamper-evident.

MD5, SHA-1, SHA-256, SHA-384 and SHA-512 for any text or file. Drag-and-drop, checksum verification and a progress bar for large files.

Convert between Base64, Base64url, URL encoding, HTML entities and hex — all in one place. Useful for debugging payloads and inspecting encoded strings.

Dissect any URL — scheme, host, path, parameters, fragment. Detect homograph attacks, IDN punycode, suspicious TLDs and phishing patterns without clicking.

Extract EXIF, XMP and IPTC metadata from images and documents without uploading them. Reveals GPS coordinates, device model, software and timestamps.

See exactly what your browser reveals to every site you visit. Canvas hash, WebGL renderer, hardware signals, fonts, timezone and a composite uniqueness score — all computed locally.

Search and browse CVEs directly from the NVD. Filter by severity, CVSS score, CWE and affected product. Live data — no account, no API key required.

Subnet masks, broadcast addresses, usable host ranges and wildcard masks — instant network math. Supports IPv4 with visual breakdown of each octet.

Query registration data for any domain — registrar, creation and expiry dates, name servers and registrant details. Useful for domain due diligence and OSINT investigations.

Look up any IP address — geolocation, ASN, ISP, organisation, country and timezone. Supports IPv4 and IPv6. Automatically detects your own IP on load.

Check any IP against major DNS-based blacklists (DNSBLs) for spam, malware or abuse flags. Results returned in seconds via DNS-over-HTTPS — no server, no logs.

Decode any JSON Web Token — colour-coded header, payload and signature. Registered claims inspector, expiry status and in-browser signature verification for HMAC and RSA/ECDSA.

Real-time entropy score, crack-time estimates across four attack scenarios, pattern detection and a HaveIBeenPwned breach check using k-anonymity.

Test and debug regular expressions against live input with match highlighting and capture group inspection. Supports flags and real-time evaluation.
