Encrypt and lock sensitive files, photos, PDFs, and archives client-side using military-grade AES-256 GCM and PBKDF2 with zero cloud transmission.

Interactive 104-key ANSI keyboard layout tester. Detect dead switches, verify anti-ghosting with N-key rollover counter, and inspect raw event keycodes with click sounds.

Fullscreen monitor diagnostic tool to spot dead pixels, stuck subpixels, color uniformity, and backlight bleeding across 9 primary calibration colors plus high-speed pixel restorer.

Test webcam video resolution, actual framerate (FPS), mirror flip, take snapshot photos, and monitor microphone volume VU decibel meters with 100% client privacy.

Diagnose faulty mouse switches (detect double-click chatter <80ms), test all 5 mouse buttons & scroll wheel, measure CPS speed, and test 10-point multi-touch displays.

Measure Shannon entropy in bits, detect dictionary patterns, inspect character composition pools, and simulate brute-force crack times across RTX 4090 GPU rigs. 100% private in-browser.

Discover exact geographic location, Autonomous System (ASN), ISP, and coordinates for any IP address, with real-time WebRTC private IP leak auditing and CDN ping latency measurements.

Verify file integrity, detect bitrot corruption, and compare SHA-256, SHA-512, SHA-1, and MD5 hashes entirely inside your browser using Web Crypto API.

Calculate usable host ranges, broadcast addresses, wildcard masks, and inspect 32-bit binary network versus host bit boundaries.

Decode X.509 PEM certificates client-side. Inspect SAN domains, validity dates, issuer, key size, and SHA-256 fingerprints.

Calculate Shannon entropy bits, character pool size & brute force crack time across throttled, GPU, and supercomputer tiers.

Generate & verify RFC 6238 Time-based One-Time Passwords with HMAC-SHA1/256/512, 30s wheel & drift inspection.

Encode and decode Bitcoin, Solana, and IPFS Base58 strings with double-SHA256 checksum validation and hexadecimal inspection.

Generate cryptographically secure 2048-bit and 4096-bit RSA PEM key pairs in browser using Web Crypto API with live encryption verification.
