(AutoIt) HMAC SHA-1 Matching FIPS Examples

Provides an example of computing an HMAC-SHA1 digest to duplicate the FIPS examples at http://csrc.nist.gov/publications/fips/fips198/fips-198a.pdf

; This example assumes the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

$oCrypt = ObjCreate("Chilkat.Crypt2")

Local $strToSign = "Sample #1"

; 64-byte key
Local $sKey = "000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f202122232425262728292a2b2c2d2e2f303132333435363738393a3b3c3d3e3f"

; The expected result:
; (from Appendix A.1 at http://csrc.nist.gov/publications/fips/fips198/fips-198a.pdf )
Local $sExpectedResult = "4f4ca3d5d68ba7cc0a1208c9c61e9c5da0403c0a"

; Here is the code to duplicate the results:
$oCrypt.HashAlgorithm = "sha-1"
$oCrypt.EncodingMode = "hex"
$oCrypt.MacAlgorithm = "hmac"

$oCrypt.SetMacKeyEncoded($sKey,"hex")

Local $sMac
$sMac = $oCrypt.MacStringENC($strToSign)

ConsoleWrite("Computed: " & $sMac & @CRLF)
ConsoleWrite("Expected: " & $sExpectedResult & @CRLF)
