WPA PSK (Raw Key) Generator

The Wireshark WPA Pre-shared Key Generator provides an easy way to convert a WPA passphrase and SSID to the 256-bit pre-shared ("raw") key used for key derivation.

Directions:
Type or paste in your WPA passphrase and SSID below. Wait a while. The PSK will be calculated by your browser. Javascript isn't known for its blistering crypto speed. None of this information will be sent over the network. Run a trace with Wireshark if you don't believe us.
