convert _StringEncrypt to PHP

2 posts in this topic

I have tried to convert the _StringEncrypt function to php but I got stuck after handling all erors.

Now I do not have errors, but it does nothing....could someone help me?

This is the original Autoit _StringEncrypt() function:

CODE

; #FUNCTION# ====================================================================================================


================
; Name...........: _StringEncrypt
; Description ...: An RC4 based string encryption function.
; Syntax.........: _StringEncrypt($i_Encrypt, $s_EncryptText, $s_EncryptPassword[, $i_EncryptLevel = 1])
; Parameters ....: $i_Encrypt        - 1 to encrypt, 0 to decrypt.
;                 $s_EncryptText     - Text to encrypt/decrypt.
;                 $s_EncryptPassword - Password to encrypt/decrypt with.
;                 $i_EncryptLevel   - Optional: Level to encrypt/decrypt. Default = 1
; Return values .: Success - The Encrypted/Decrypted string.
;                 Failure - Blank string and @error = 1
; Author ........: Wes Wolfe-Wolvereness <Weswolf at aol dot com>
; Modified.......:
; Remarks .......: WARNING: This function has an extreme timespan if the encryption level or encrypted string are too large!
; Related .......:
; Link ..........;
; Example .......; Yes

EndFunc ;==>_StringEncrypt

and attached is the php function I tryed to convert....

P.S. I posted this thread in the General->Chat section but I just realised where it was so I posted it again here...


I do not like stupid and idiot people that write idiot things...If you are one, do not write.

Don't double post. You're trying to use PHP which has nothing to do with AutoIt, I moved your other post this morning to chat.
