I have this code:
import hashlib
pass_hash = input("Enter MD5 Hash: ")
wordlist = input("Wordlist name: ")
try:
pass_file = open(wordlist, 'r')
except FileNotFoundError:
print("File not found.")
quit()
def main():
counter = 0
print(f"List count: {str(counter)} Type: alphanum")
for word in pass_file:
encoded_word = word.encode('utf-8')
digest = hashlib.md5(encoded_word.strip()).hexdigest()
counter += 1
if digest == pass_hash:
print(f"Password found: {word}")
break
else:
print("Password not found")
main()
I am trying to print the counter current stage, for example 1 gets replaced by 2 and then by 3 etc on the same line until the password hash gets cracked. Like a loading bar just with numbers iterated so far.
Use string concatenation:
stringToPrint = "List count: " + str(counter) + " Type: alphanum"
print(stringToPrint)
You can accomplish this using a carriage return:
counter = 0
for word in pass_file:
sys.stdout.write(f"\rList count: {str(counter)} Type: alphanum")
sys.stdout.flush()
counter += 1
encoded_word = word.encode('utf-8')
digest = hashlib.md5(encoded_word.strip()).hexdigest()
if digest == pass_hash:
print(f"\nPassword found: {word}")
break
You need to flush the stdout stream to ensure that it gets written (normally the output stream will wait for a substantial buffer or a line break (\n) to print out, so you'll need to manually flush.
You also need to add a line break when the password is found, since we don't include one when writing the counter.
I wrote a program that reads in a file. The name of the file was passed into my program as a command-line parameter. Each line of the file contained 3 fields, separated by a vertical bar, or pipe ("|").
The file contained information about books so each line contains a title(ex. Les Miserables), an author, and a genre which I put into three arrays:
title = []
author = []
genre = []
I am trying to input a word like "Les" and get the specific elements from the arrays and print it like "(Fiction), Les Miserables by Victor Hugo".
This is my code so far:
for word in myArray:
fields = word.split(|)
title.append(fields[0])
author.append(fields[1])
genre.append(fields[2])
entry = raw_input()
if entry == T or t:
titlEntry = raw_input("Please enter title:")
n = len(title)
for i in range(0,n):
if titlEntry == i:
print "(" + genre[i] + ") " + title[i] + " by " + author[i]
Please help
First of all, this is not the way to do it; a dictionary would be better and I would ask you look into other structures as well. Also, think about sanitizing the input you read from the command line. However, to get you going, you are close. Try:
titlEntry = raw_input("Please enter title:")
n = len(title)
for i in range(0,n):
if titlEntry == title[i]:
print "(" + genre[i] + ") " + title[i] + " by " + author[i]
I am needing a bit of help on my encryption program. Instead of having the program just move the letters by two (c would become a or r would become p) I'd like to be able to have it reference 2 lists, the first one going from a-z normally and the other with letters in different order to act as the encrypt/decrypt side. Hopefully that makes sense. Here's what i have so far.
result = ''
choice = ''
message = ''
while choice != 0:
choice = input("\n Do you want to encrypt or decrypt the message?\n 1 to encrypt, 2 to decrypt or 0 to exit program. ")
if choice == '1':
message = input('\nEnter message for encryption: ')
for i in range(0, len(message)):
result = result + chr(ord(message[i]) - 2)
print(result + '\n\n')
result = ''
if choice == '2':
message = input('\nEnter message to decrypt: ')
for i in range(0, len(message)):
result = result + chr(ord(message[i]) + 2)
print(result + '\n\n')
result = ''
elif choice != '0':
print('You have entered an invalid input, please try again. \n\n')
This works fine and dandy but i'd like to have the lists. Lets say list 1 is A,B,C,D,E and list 2 would be W,N,U,D,P. just for ease of use purposes.
Here is a solution, for small letters only. It can easily be modified to handle also capital letters, by adding them to the text strings.
As can be seen, the space character is at the same position in both lists. This is not necessary, as any character can be translated to any other. However if the decrypted or encrypted is not containing unique characters only, the program will break down.
decrypted = b"abcdefghijklmnopqrstuvwxyz "
encrypted = b"qwertyuiopasdfghjklzxcvbnm "
encrypt_table = bytes.maketrans(decrypted, encrypted)
decrypt_table = bytes.maketrans(encrypted, decrypted)
result = ''
choice = ''
message = ''
while choice != '0':
choice = input("\n Do you want to encrypt or decrypt the message?\n 1 to encrypt, 2 to decrypt or 0 to exit program. ")
if choice == '1':
message = input('\nEnter message for encryption: ')
result = message.translate(encrypt_table)
print(result + '\n\n')
elif choice == '2':
message = input('\nEnter message to decrypt: ')
result = message.translate(decrypt_table)
print(result + '\n\n')
elif choice != '0':
print('You have entered an invalid input, please try again. \n\n')
Ok, so a few things here...
First I'll give you exactly what you were looking for and explain what I used and some of the changes that needed to be made to your original code. Then I'll explain some inherent issues what what you're trying to do and suggest some areas to read up on/some ways you might want to improve what you've got.
Here's the code you're looking for (while retaining the same flow as what you submitted put above):
import random
result = ''
choice = ''
message = ''
characters_in_order = [chr(x) for x in range(32,127)]
while choice != 0:
choice = input("\n Do you want to encrypt or decrypt the message?\n 1 to encrypt, 2 to decrypt or 0 to exit program. ")
if str(choice) == '1':
message = input('\nEnter message for encryption: ')
r_seed = input('Enter an integer to use as a seed: ')
random.seed(r_seed)
shuffled_list = [chr(x) for x in range(32,127)]
random.shuffle(shuffled_list)
for i in range(0, len(message)):
result += shuffled_list[characters_in_order.index(message[i])]
print(result + '\n\n')
result = ''
elif str(choice) == '2':
message = input('\nEnter message to decrypt: ')
r_seed = input('Enter an integer to use as a seed (should be the same one used to encrypt): ')
random.seed(r_seed)
shuffled_list = [chr(x) for x in range(32,127)]
random.shuffle(shuffled_list)
for i in range(0, len(message)):
result += characters_in_order[shuffled_list.index(message[i])]
print(result + '\n\n')
result = ''
elif str(choice) != '0':
print('You have entered an invalid input, please try again. \n\n')
You'll notice that I set a global 'characters in order' list, which is just every ASCII character (32-126) in order. I also imported the 'random' module and used this to shuffle the characters in order according to a seed that the user inputs. As long as this seed is the same on the encryption and decryption end, it will produce the same shuffled list and it should work to encrypt or decipher the same string. Also notice the str() around your input choices. Without that, the user had to input '1', rather than 1 to submit a choice without an error.
All of that said...
Notice that the way the new function works is by looking at a character's index in one list and pulling out the character at that index in another. The method you were using, of incrementing or decrementing a character's ASCII code is basic (though not much more basic than this), but it also has a pretty critical flaw, which is that characters on one end or another of the ASCII set wouldn't return ASCII characters. If you were encrypting it at a bit-level, which would be preferred, this wouldn't matter/would be irrelevant, but here you're not going to get the kind of string back that you want if you were to, for example, enter a [space] (ASCII 32) into your plaintext to be encrypted.
If you're interested, you might want to read up on symmetric key encryption/DES for some ideas on how encryption is really done, though props on the start/interest and this can certainly be a fun way to create some sort of cryptogram puzzle or something along those lines. I won't pretend to be any kind of expert, but I can at least point you in the write direction. (https://en.wikipedia.org/wiki/Data_Encryption_Standard https://en.wikipedia.org/wiki/Symmetric-key_algorithm)
Consider having your code read in a .txt file and print out to a .txt file, rather than using user input for the message.
Again, I'm not an expert by any means and there are definitely some fun uses of the kind of program you're aiming for, just trying to point you in the right direction if this is something that you're interested in. Hope all of that is helpful!
Here is my solution. It uses a randomizer to encrypt the file by assigning a ASCII value to the plain text and randomly shifts it around.
from random import randint
import sys

input1=int(input(""" please select what you want to do:
1.Encrypt

"""))#menu to choose what you want to do
if input1==1:
encrypt() #takes you to the encrypt function
elif input1==2:
decrypt()#takes you to the decrypt function
elif input1==3:
enxtended()#takes you to the extended encryption function
elif input1==4:
sys.exit #exits the program
else:
print("invalid entry try again")
menu()
def encrypt():
file_name=str(input("please enter the name of the file that you want to open\n"))
try:
text_file=open(file_name + ".txt","r")#puts the text file into read
text_file=text_file.read()#reads the text file
print(text_file)#prints the strings in the document
except:
print("error try again")
encrypt()
random(text_file)
def random(text_file):
list1=("")#creates blank string
for x in range (0,8):
num=(randint(33,126))#generates a random number between33 and 126
ascii1=chr(num) #converts it into an ascii character
list1=list1+ascii1#adds the ascii character to the blank string list1
print (f"your 8 key code is {list1}") #prints 8 character code
offset(list1,text_file)
def offset(list1,text_file):
total=0
for x in range (8,):
total=total+ord(list1[x]) #turns each character into an ascii value
total=total/8 #divides it by
total=round(total,0)#rounds it to 0 decimel places
print(total)
total=total-32#minuses 32 from total
print(f"your offset factor is {total}")
encrypting(total,text_file)
def encrypting(total,text_file):
length=len(text_file)
string1=("")
for x in range (length,):
numascii=ord(text_file[x])#turns the characters into its ascii value
numascii=int(numascii)#makes sure they are integers
if numascii==32:
letter=chr(32)#converts spaces back into spaces
string1=string1+letter#adds space to thestring
else:
numascii1=numascii+total#adds the character value to the offset factor
numascii1=int(numascii1)#makes sure it is an integer
if numascii1>126:# if the ascii value is great then 126

string1=string1+letter#add it to the string
else:
letter=chr(numascii1)#turn the ascii value into a character
string1=string1+letter#add it to the string
print(f"your encrypted file is {string1}")
savefile(string1)

I have written separate programs for encryption and decryption. Both of these use file manipulation techniques. Use the username 'eggs' and password 'chicks' so that not anyone can see my secret code. I have used hashlib for more security. Just change the User 'Soumajit' to your respective Username to make it work. The first one is encryption and the next one is for decryption.

I need to prompt a user for input until 2 blank lines are given in a row, please note that the input read may have blank lines in it for clarity purposes, I will need two blank lines given back to back before it breaks.
So far I've come up with this:
def gather_intel():
done = False
while done is False:
data = raw_input("Copy and paste the work log: ")
if data is None:
done = True
How ever this will end as soon as a single blank line is given, I've also tried adding another while loop to it:
def gather_intel():
done = False
while done is False:
data = raw_input("Copy and paste the work log: ")
while data != "" + "\n" + "":
data = raw_input("Copy and paste the work log: ")
if data == "" + "\n" + "":
done = True
However this one is an infinite loop and will never end. How can I prompt a user for input, until there are two blank lines given to the input back to back?
number_of_empty_responses = 0
while True:
data = raw_input("Copy and paste the work log: ")
if data == "":
number_of_empty_responses += 1
if number_of_empty_responses == 2:
break
else:
number_of_empty_responses = 0
pass # Received data, perform work.
For future me or somebody else. The input until 2 conscutive newline characters:
def handy_input(prompt='> '):
'An `input` with 2 newline characters ending.'
all_input_strings = ''
# prompt the user for input
given_input = input(prompt)
all_input_strings += given_input
# and handle the two newline ending
while given_input:
# if previous input is not empty prompt again
given_input = input('')
all_input_strings += '\n' + given_input
return all_input_strings
And the answer to the question with 2 empty lines:
def empty_lines_input(prompt='> ', n_lines=2):
'An `input` with `n_lines` empty line ending.'
all_input_strings = ''
# prompt the user for input
given_input = input(prompt)
all_input_strings += given_input
# and handle the two newline ending
while n_lines>0:
# if previous input is not empty prompt again
given_input = input('')
all_input_strings += '\n' + given_input
# check if it was an empty line
if not given_input:
n_lines -= 1
else:
n_lines = 2
return all_input_strings
So I have a question that requires this The features : color,size,flesh and class are separated by spaces. Write a Python program that asks the user for the names of the input file (in this case animals.txt) and the output file (any name). The program reads in the lines of the input file, ignores comment lines (lines starting with #) and blank lines and computes and prints the answers to the following questions:
Total number of animals?
Total number of dangerous animals?
Number of large animals that are safe?
Number of animals that are brown and dangerous?
Number of safe animals with red color or hard flesh?
So I finished the program and everything seems to be working but so far when I enter the code and initiate the program, everything works, no errors, nothing but no output file gets generated. I don't know what is wrong exactly but if someone could point me in the right direction it would be highly appreciated.
import os.path
endofprogram = False
try:
filename1 = input("Enter the name of input file: ")
filename2 = input("Enter the name of output file: ")
while os.path.isfile(filename2):
filename2 = input("File Exists! Enter new name for output file: ")
infile = open(filename1, 'r')
ofile = open(filename2, "w")
except IOError:
print("Error reading file! Program ends here")
endofprogram = True
if (endofprogram == False):
alist = []
blist = []
clist = []
largesafe = 0
dangerous = 0
browndangerous = 0
redhard = 0
for line in infile:
line = line.strip("\n")
if (line != " ") and (line[0] != "#"):
colour, size, flesh, clas = line.split('\t')
alist = alist.append(colour)
animals = alist.count()
while clas == "dangerous":
dangerous = dangerous + 1
while size == "large" and clas == "safe":
largesafe = largesafe + 1
while colour == "brown" and clas == "dangerous":
browndangerous = browndangerous + 1
while colour == "red" and flesh == "hard":
redhard = redhard + 1
ofile.write(print("Animals = \n", animals))
ofile.write(print("Dangerous = \n", dangerous))
ofile.write(print("Brown and dangerous = \n", browndangerous))
ofile.write(print("Large and safe = \n", largesafe))
ofile.write(print("Safe and red color or hard flesh= \n", redhard))
infile.close()
ofile.close()
Your indentation has completely messed the program up. The biggest offender is this section:
except IOError:
print("Error reading file! Program ends here")
endofprogram = True
if (endofprogram == False):
The if line will only ever be executed right after the endofprogram = True line, at which point endofprogram == False will be false, and so nothing in the if block — which include the rest of the program — will be executed. You need to dedent everything from the if onwards by one level.
Maybe you can remove the print inside ofile.write
ofile.write(print("Animals = \n", animals))
to
ofile.write("Animals = \n" + str(animals))
