Encrypt private file with password using crypt.au3

8 posts in this topic

Hey everyone,

I want to encrypt a file, lets say file.txt with a password. I do not want to store the password but I want to be able to encrypt the data against the password so it is possible to decrypt it with the correct password, if its not it returns an error. Is this possible?

I looked at crypt.au3 but I have no idea on UDFs and whats going on. I also searched the forums and got nothing, and the help file does not cover crypt.au3.

Can anyone help me here?

I am assuming you have enough information here to understand it, as I do not have any code I am able to give you at the moment.

Thanks,

shanet

shanet,

If you use the "C:\Program Files\AutoIt3\AutoIt3Help.exe" Help wrapper, or open the "C:\Program Files\AutoIt3\AutoIt.chm" file directly you will find the Crypt UDF Help pages under <User Defined Function Reference> at the bottom of the index. Everything you have asked is possible and explained therein. :P

The Crypt UDF functions are very easy to use, but if you still have problems, please come back. :x

This might help?

http://dundats.mvps.org/help/html/libfunctions/Encryption%20Management.htm

Or 'Encryption Management' in the User Defined Function section of the local help file.

I went to encryption management under user defined functions and it tells us to include encryption.au3 which I dont have under my include folder?

That's a typo, it should be Crypt.au3, and that's what you see at the top of all the examples under each function.

If you are only wanting to encrypt a text file, take a look at _StringEncrypt in the help file. It's pretty easy to use. It used RC4 encryption.

http://en.wikipedia.org/wiki/RC4

Encryption example:

#Include <String.au3>
$orig = FileRead("text.txt")
$encryp = _StringEncrypt(1, $orig, "password") 
FileWrite("text_encrypted.txt", $encryp)

Decryption example:

#Include <String.au3>
$orig = FileRead ("text_encrypted.txt")
$decrypt = _StringEncrypt(0, $orig, "password")
FileWrite("text_decrypted.txt", $decrypt)

Edit: MrPPP beat me to it.

#include <ByteMe.au3>

Not exactly. The _StringEncrypt() function uses an RC4-Like function. There are AutoIt implementations of standard RC4 posted, but the _StringEncrypt() function does not use it.

The functions of the Crypt.au3 UDF would be better.
