I am getting an error while encrypting a file.
C:\Users\username>python xor_encryptor.py raw.txt > new.txt
Traceback (most recent call last):
File "C:\Users\username\xor_encryptor.py", line 19, in <module>
ciphertext = xor(plaintext, KEY)
File "C:\Users\username\xor_encryptor.py", line 10, in xor
output_str += chr(ord(current) ^ ord(current_key))
TypeError: ord() expected string of length 1, but int found
The xor_encryptor script is:
import sys
KEY = "x"
def xor(data, key):
key = str(key)
l = len(key)
output_str = ""
for i in range(len(data)):
current = data[i]
current_key = key[i % len(key)]
output_str += chr(ord(current) ^ ord(current_key))
return output_str
def printCiphertext(ciphertext):
print('{ 0x' + ', 0x'.join(hex(ord(x))[2:] for x in ciphertext) + ' };')
try:
plaintext = open(sys.argv[1], "rb").read()
except:
print("File argument needed! %s " % sys.argv[0])
sys.exit()
ciphertext = xor(plaintext, KEY)
print('{ 0x' + ', 0x'.join(hex(ord(x))[2:] for x in ciphertext) + ' };')
Kindly give an appropriate solution.

script tells me that unpack requires a buffer of 2 bytes.
maybe someone finds that error.
Thats a script to read a file with hex adresses and compare it with clear text file.
But everytime i get this struct.error

Could you help me to solve this problem?
Fixed it.

I'm getting an error even after setting base64 encoding:
Traceback (most recent call last):
File "api_tufin_5.py", line 41, in <module>
main(sys.argv[1:])
File "api_tufin_5.py", line 28, in main
headers['Authorization'] = 'Basic ' + base64.b64encode(user + ':' +
password)
TypeError: can't concat bytes to str
This is my code:
import requests, sys, base64, collections, json
# global vars
server_ip = 'url'
headers = {}
user = b'username'
password = b'password'
debug = False
def http_get(url, headers=headers):
try:
r = requests.get(url=url, headers=headers, verify=False)
except requests.exceptions.RequestException as e:
print >> sys.stderr, e
return
if debug:
print (r.text)
http_result = collections.namedtuple('HTTP_Result', ['status',
'text'])
return http_result(r.status_code, r.text)
def main(argv):
headers['Accept'] = 'application/json'
headers['Authorization'] = 'Basic ' + base64.b64encode(user + ':' +
password)
r = http_get('url/securechangeworkflow/api/securechange/tickets?
status=In Progress&count=10&start=1&expand_links=false')
if r.status != 200:
print >> sys.stderr, "Failed to get devices"
print >> sys.stderr, "Status: ", r.status
return -1
print (r.text)
if __name__ =='__main__':
main(sys.argv[1:])
Why would it still show an error when base64 has been encoded? What would cause it to not concat bytes to str? Use of the + should be able to merge two strings into a single object.
I'm trying to find the length of a password before going on with my program but python keeps telling me that I'm instead trying to compute the length of a bool:
input_name = input('\nWe need you name: ')
if input_name in members:
while True:
input_pass = input('Input your password: ')
if len(input_pass == 0):
print("Can't be null!")
continue
else: break
else:
print('Sorry, your not part of the League.')
bin_1 = input('Would you like to join?')
Traceback:

I recently got a raspberry pi and a book to go along with it(Raspberry Pi Cookbook). One of the projects is controlling the GPIO pins on the RPi via a webpage. When I first ran the code after typing it out, I received a bunch of errors so, I tried running the code listed on the books github page:
from bottle import route, run
import RPi.GPIO as GPIO
host = '192.168.1.8'
GPIO.setmode(GPIO.BCM)
led_pins = [18, 23, 24]
led_states = [0, 0, 0]
switch_pin = 25
GPIO.setup(led_pins[0], GPIO.OUT)
GPIO.setup(led_pins[1], GPIO.OUT)
GPIO.setup(led_pins[2], GPIO.OUT)
GPIO.setup(switch_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
def switch_status():
state = GPIO.input(switch_pin)
if state:
return 'Up'
else:
return 'Down'
def html_for_led(led):
l = str(led)
result = " <input type='button' onClick='changed(" + l + ")' value='LED " + l + "'/>"
return result
def update_leds():
for i, value in enumerate(led_states):
GPIO.output(led_pins[i], value)
#route('/')
#route('/<led>')
def index(led="n"):
print(led)
if led != "n":
led_num = int(led)
led_states[led_num] = not led_states[led_num]
update_leds()
response = "<script>"
response += "function changed(led)"

When I run the code(sudo python web_control.py) I get a invalid literal for int() with base 10: 'favicon.ico' error. Here is the traceback:

Any idea what is going on here? Any help is greatly appreciated.
what does your
print led
show ?
they say that led is not an int so the error could be from there
