WiFi Security Toolkit
Check WPA passphrase strength with real PBKDF2 derivation, plan WiFi channels, decode EAPOL handshake frames, calculate signal strength, and generate WiFi QR codes — five tools covering setup, diagnostics, and the 4-way handshake. All run entirely in your browser.
How these fit together
WPA/WPA2 PSK Strength Checker derives the real PBKDF2 PMK from a passphrase and SSID and flags weak passphrase choices before you actually configure a network. Setting up a network to share with guests or on a new device? WiFi QR Code String Generator builds the correctly escaped scannable-code string. Once it's up, WiFi Channel Planner finds the least-congested 2.4GHz channel or checks 5GHz channel-bonding overlap against nearby networks, and WiFi Signal Strength Calculator turns an RSSI reading into a quality percentage and an estimated distance. Analyzing a captured 4-way handshake instead? EAPOL Handshake Frame Decoder decodes the raw frame and identifies which of the four messages it is. Need that same handshake (or a captured PMKID) in a crackable format instead? Hashcat 22000 Converter builds the -m 22000 hash line hashcat expects.
