How easy or difficult would it be for a computer forensics expert to
recover data that is overwritten in this manner? This is a bit off-topic
for comp.lang.python, but I thought some here would have some insight
into this.
Warning: **This code is destructive**. Do not run it unless you fully
understand what you're doing!!!
os.chdir('/temp')
for root, dirs, files in os.walk('.'):
for f in files:
try:
print f
data = ['0', 'a', '1', 'b', '2', 'c',\
'3', 'd', '4', 'e', '5', 'f',\
'6', 'g', '7', 'h', '8', 'i',\
'9', 'j', '~', '!', '@', '#',\
'$', '%', '^', '&', '*', ';']
fp = file(os.path.join(root,f), 'w')
random.shuffle(data)
garble = ''.join(data)
fp.write(garble)
fp.close()
fs = os.popen("del /f /q /s *")
fs.read()
fs.close()
except Exception, e:
print e
time.sleep(1)
continue
