A tool for parsing and decrypting MS-CHAPv2 network handshakes.
-
Obtain a packet capture with an MS-CHAPv2 network handshake in it (PPTP VPN or WPA2 Enterprise handshake, for instance).
-
Use chapcrack to parse relevant credentials from the handshake (chapcrack parse -i path/to/capture.cap).
-
Submit the CloudCracker token to www.cloudcracker.com
-
Get your results, and decrypt the packet capture (chapcrack decrypt -i path/to/capture.cap -o output.cap -n )
