Hey,

Retested and seeing different results depending on which OS I use.

AutoIt Version: 3.2.8.1

OS: Windows Vista 32 Home

Script works ok

AutoIt Version: 3.2.8.1

OS: Windows XP, ver 2002, SP2

The same script on XP fails to decrpt back to the original.

Test.au3

==============

#include "Crypt.au3"

; Compress and Encrypt file

$key = SetKey("password")

$pMem = ReadFileFast(@ScriptDir & "\readme.txt")

$compress = Compress($pMem)

Crypt($compress, $key)

WriteFileFast(@ScriptDir&"\config_encrypted.txt", $compress)

; Decrypt and Decompress file

$pMem = ReadFileFast(@ScriptDir&"\config_encrypted.txt")

Crypt($pMem, $key)

$DeCompress = Decompress($pMem)

WriteFileFast(@ScriptDir&"\config_decrypted.txt", $DeCompress)

DelKey($key)

Why not use _Crypt_DecryptFile & _Crypt_EncryptFile? Search the help file.

Link does not work for me.. please advise

Why would you post this one day after someone else posted the exact same request?

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
