High quality, simple random password generator

Question

I\'m interested in creating a very simple, high (cryptographic) quality random password generator. Is there a better way to do this?

import os, random, strin         


        

Answer 1

A little bit off topic, but I made this, using also TKinter. Hope it can helps:

import os, random, string
from tkinter import *

def createPwd():
    try:
        length = int(e1.get())
    except ValueError:
        return
    chars = string.ascii_letters + string.digits + '!@#$%^&*()?\/'
    random.seed = (os.urandom(1024))
    e2.config(state=NORMAL)
    e2.delete(0,'end')
    e2.insert(0,''.join(random.choice(chars) for i in range(length)))
    e2.config(state="readonly")

mainWindow = Tk()
mainWindow.title('Password generator')

mainWindow.resizable(0,0)

f0 = Frame(mainWindow)

f0.pack(side=TOP,pady=5,padx=5,fill=X,expand=1)

Label(f0,text="Length: ",anchor=E).grid(row=0,column=0,sticky=E)

e1 = Entry(f0)
e1.insert(0,'12')
e1.grid(row=0,column=1)

btn = Button(f0,text="Generate")
btn['command'] = lambda: createPwd()
btn.grid(row=0,column=2,rowspan=1,padx=10,ipadx=10)

Label(f0,text="Generated password: ",anchor=E).grid(row=1,column=0,sticky=E)
e2 = Entry(f0)
e2.grid(row=1,column=1)

createPwd()

#starting main window
mainWindow.mainloop()
