That didn't work very well either :(. Ok, but now I can offer a real secure solution: You can have real encryption in Python using this modules: http://www.amk.ca/files/python/crypto/pycrypto-2.0.1.tar.gz and http://sourceforge.net/projects/yawpycrypto Below I post a code-example that I've written some time ago. With it, encrypting text is rather easy. Then you have to program a start-script, that reads in your script and the decryption-key. The decryption-key must be encrypted too. Such a encrypted key can be generated by the modules if you don't pass a password to my function "doEncrypt(). The decryption-key must then be hidden somewhere within the encrypted program-script. That's because, if the user knows where to find the key, he can decrypt the program-script. If your start-script is written, everything should work automatically, one shouldn't nearly notice the decryption-process. Ok, here's my example code, how to encrypt and decrypt some text with the modules: ---------------------------------------------------------------------------- #!/usr/bin/env python import os import sys import base64 from yawPyCrypto.Cipher import DecryptCipher, EncryptCipher from yawPyCrypto.Cipher import ZipDecryptCipher, ZipEncryptCipher from yawPyCrypto.Constants import CIPHER_BLOWFISH, MODE_CBC def doEncrypt(text, passw = None): e = EncryptCipher(passw, CIPHER_BLOWFISH, MODE_CBC) e.feed(text) e.finish() encryptedtext = e.data if passw != None: passwr = passw else: passwr = e.password a = (encryptedtext, passwr) return a def doDecrypt(encryptedtext, passw): d = DecryptCipher(passw) d.feed(encryptedtext) d.finish() decoded = (d.data) return decoded # Calling the encryption routine. # If you just pass the text to encrypt, a password is generated: a = doEncrypt("For your eyes only !", "Melina") # Just trying to clean the screen: if sys.platform == "win32": os.system("cls") else: os.system("clear") print print "Hello !" print print "I just encrypted some text. It looks like this now:" print print base64.b64encode(a[0]) print print 'Please notice, that I just encoded the text once more using "base64.b64encode()" to make it printable.' print print "The password for decryption is: " print print base64.b64encode(a[1]) print print "Let's decrypt again (the original password must be passed without b64encoding):" print print doDecrypt(a[0], a[1]) print ---------------------------------------------------------------------------- See you H. -- http://mail.python.org/mailman/listinfo/python-list
