[Python] Simple Base64 Encryption / Decryption Tool

[MrGrj]

Un programel simplu facut in pauza de masa. Enjoy:

__author__ = "MrGrj"

import binascii

def bas64decryption():
    encoded_string = raw_input("Please insert the base64 encrypted text:")
    decoded_string = encoded_string.decode('base64')

    if encoded_string is None:
        print 'You inserted a null string. Please enter a valid string next time !'
    else:
        print 'Your decoded string:' + ' ' + decoded_string

def base64encryption():
    decoded_string = raw_input("Please insert the text that you want to encode:")
    encoded_string = decoded_string.encode('base64')

    if decoded_string is None:
        print 'You inserted a null string. Please enter a valid string next time !'
    else:
        print 'Your encoded string:' + ' ' + encoded_string

if __name__ == "__main__":
    menu = {}
    menu['1'] = "Base 64 decryption."
    menu['2'] = "Base 64 encryption."
    menu['3'] = "Exit."
    while True:
        options = menu.keys()
        options.sort()
        for entry in options:
            print entry, menu[entry]

        selection = raw_input("What would you like to do? ")
        if selection == "1":
            try:
                bas64decryption()
            except binascii.Error:
                print "This is not a base64 encoded string!"

        elif selection == "2":
            try:
                base64encryption()
            except binascii.Error:
                print "Something went wrong! Please try again"

        elif selection == "3":
            print "Bye-bye"
            break
        else:
            print "This is not a valid choice !"

O sa revin cu update-uri in topicul asta cu alte functii de decoding / encoding. Apoi, cu restul membrilor care stiu python sa facem ceva misto, optimizat, etc. Asta daca se vrea si eu timp. @MasterLight

O simpla observatie, de ce bas64encryption() decodeaza textul base64 si base64decryption(): il encodeaza? Nu ar trebui sa fie invers numele?

[hades]

M-am tot uitat si nu intelegeam de ce-ai importat binascii pentru asta, tinand cont ca pe stringuri ai functia built-in encode/decode. Apoi am vazut ca e pentru exceptie.

Heh, funny.

Da, typo. Thanks

@alecseu teoretic asta era ideea sa fac fara nici un import dar arata urat eroarea aia daca bagai un string aiurea
