Encrypt a text from a file and ...

[OmYcroN 0]

What i want to do :

- read a file that contains ini sections of an ini file but encrypted using a function (is there one for it ?)

- decrypt it and send the results to IniReadSection() (is it possible ?)

I don't know how to make a function for crypt/decrypt and i'm not sure about the IniReadSection() that usese a file as parameter and not a text from a variable.

In other words my file file.dat :

#$G%$##%^GHG

And using a function to decrypt it :

[section]

Key = Value

And then pass this to IniReadSection()

If u have other ideas for this tell me, please.

depends on the type of encryption

[Mat 364]

there is already encrypt, and it has decrypt built in...

look in the help file for _StringEncrypt (under string management). it has it all there.

you probably want to save the converted cop to a temporary file, and then read that... unless you want to declare all the keys etc your self!!

Hope it helps

OmYcroN,

Here is something from my snippets folder which you may find useful in your project:

#include <String.au3>

; define encryption settings
Global Const $enc_pass = "ABC123"; set the encryption password
Global Const $enc_level = 2; set the encryption level (check the help file for _StringEncrypt for possible levels)

; you can use the functions in a similar manner to the default IniWrite and IniRead
_IniWrite("data.ini", "settings", "foo", "bar")
ConsoleWrite(_IniRead("data.ini", "settings", "foo", "OOPS!") & @CRLF)

; just like the default IniWrite
Func _IniWrite($sIniPath, $sIniSection, $sIniKey, $sIniValue)
    IniWrite($sIniPath, $sIniSection, $sIniKey, _StrEncrypt($sIniValue))
EndFunc  ;==>_IniWrite

; just like the default IniRead
Func _IniRead($sIniPath, $sIniSection, $sIniKey, $sIniDefault)
    Return _StrDecrypt(IniRead($sIniPath, $sIniSection, $sIniKey, _StrEncrypt($sIniDefault)))
EndFunc  ;==>_IniRead

; Encrypt a string using the default $enc_pass and $enc_level
Func _StrEncrypt($sString)
    Return _StringEncrypt(1, $sString, $enc_pass, $enc_level)
EndFunc  ;==>_StrEncrypt

; Decrypt a string using the default $enc_pass and $enc_level
Func _StrDecrypt($sString)
    Return _StringEncrypt(0, $sString, $enc_pass, $enc_level)
EndFunc  ;==>_StrDecrypt

as I have understood the ini sections are already encrypted so if they arent encrypted with the RC4 encryption _StringEncrypt wont work

mdiesel : Thank u for the idea ... i did like u said

M23 : Thanks for the code ... I can only say that _StringEncrypt takes a LOT of time for encrypting 30kb of plain text

Many thanks to both.

if you want it to be faster, use a lower encryption level, or find a different method of encryption...Possibly even a third party program that you can use...
