Attacking a Single Letter
* Repeats for all characters we want to try
An example of this loop is:
 <presyntaxhighlight lang=python>
trylist = 'abcdefghijklmnopqrstuvwxyz0123456789'
for c in trylist:
# Test this password and record Get a power traceusing our next attempt selfnextPass = password + '{}'.api.setParameterformat(['Simple Serial', 'Go Command', c ) + '"\n'])" target.go_cmd = nextPass cw.captureN(self.apiscope, self.target, None, self.capture1(aux_list, self.ktp, 1) # Get Grab the data trace and check data[153] data nextTrace = self.api.getScope().channels[0]scope.getTracegetLastTrace()
if data[153] > -0.2:
print "Success: " + c
</presyntaxhighlight>
This script will eventually stop, but you can use Ctrl+C on the command line to kill it. Make sure your script prints "Success: h"!
</li>
