Hello guys. Here is a small function to create a hash hmac similar to hash_hmac PHP function.
Supported are: SHA512,SHA256,SHA1,SHA384,MD5 and RIPEMD160.
Local $sSecret = "SecretKey"
Local $sMessage = "AutoIt Rocks!!!"
ConsoleWrite("HMAC-SHA256: " & @TAB & @TAB & _HashHMAC("SHA512", $sMessage, $sSecret) & @CRLF)
ConsoleWrite("HMAC-SHA256: " & @TAB & @TAB & _HashHMAC("SHA256", $sMessage, $sSecret) & @CRLF)
ConsoleWrite("HMAC-SHA1: " & @TAB & @TAB & _HashHMAC("SHA1", $sMessage, $sSecret) & @CRLF)
ConsoleWrite("HMAC-SHA384: " & @TAB & @TAB & _HashHMAC("SHA384", $sMessage, $sSecret) & @CRLF)
ConsoleWrite("HMAC-MD5: " & @TAB & @TAB & _HashHMAC("MD5", $sMessage, $sSecret) & @CRLF)
ConsoleWrite("HMAC-RIPEMD160: " & @TAB & _HashHMAC("RIPEMD160", $sMessage, $sSecret) & @CRLF)
Func _HashHMAC($sAlgorithm, $bData, $bKey, $bRaw_Output = False)
Local $oHashHMACErrorHandler = ObjEvent("AutoIt.Error", "_HashHMACErrorHandler")
Local $oHMAC = ObjCreate("System.Security.Cryptography.HMAC" & $sAlgorithm)
If @error Then SetError(1, 0, "")
$oHMAC.key = Binary($bKey)
Local $bHash = $oHMAC.ComputeHash_2(Binary($bData))
Return SetError(0, 0, $bRaw_Output ? $bHash : StringLower(StringMid($bHash, 3)))
EndFunc ;==>_HashHMAC
Func _HashHMACErrorHandler($oError)
;Dummy Error Handler
EndFunc ;==>_HashHMACErrorHandler
It requires .NET Framework 2.0 or higher.
