[已解决]HMAC_SHA256算法结果与python不一样？
本帖最后由 oceanwind 于 2021-12-26 20:09 编辑这两天在试腾讯云接口，以下为链接Hash HMAC - AutoIt Example Scripts - AutoIt Forums (autoitscript.com)的代码附轻微修改。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))
$rt = SetError(0, 0, $bRaw_Output ? $bHash : StringLower(StringMid($bHash, 3)))
;~ Return SetError(0, 0, $bRaw_Output ? $bHash : StringLower(StringMid($bHash, 3)))
;~
$tlen = StringLen($rt)
$hmac256str = ""
For $i = 1 To $tlen - 1 Step 2
;~ ConsoleWrite($i & @CR)
$hmac256str &= "\x" & StringMid($rt, $i, 2)
Next
Return $hmac256str
EndFunc ;==>_HashHMAC256结果如下：
HMAC-SHA256: \x11\xb7\x5d\x84\x5a\x07\xfc\x5c\x0a\x6c\xc3\xdb\xdb\x9c\x5c\x53\xd3\x03\x41\x29\xe3\x39\x4f\x56\xa2\xf1\x66\x49\xb6\x1a\x5c\x54
以下为PYthon代码：
def sign(key, msg):
return hmac.new(key, msg.encode("utf-8"), hashlib.sha256).digest()
key = "SecretKey"
data = "AutoIt Rocks!!!"
# secret_date = sign(("TC3" + secret_key).encode("utf-8"), date)
secret_date1 = sign(key.encode("utf-8"), data)
# print('----------16----------("TC3" + secret_key).encode("utf-8")-------------')
# print(("TC3" + secret_key).encode("utf-8"))
print('----------18----------secret_date-------------')
# print(secret_date)
print(secret_date1)PYthon代码运行结果如下 ：
b'\xf1\xcbMQ\x8a\x0e\xda\x9d\\\xbb\xfd\xb7\x85\t\x83\xf1\xe6\x03\xee\xaeHN\xde\xa7nM\xd8\xd8\xde\xb5Un'
这个python结果与au3结果有差异，python有些字符没转成asc码，有朋友知道怎么回事吗？
我也遇到过，没解决 看错版了，应该发在提问版块。 本帖最后由 oceanwind 于 2021-12-26 20:10 编辑
英文论坛有朋友回复了How to get binary result from HMAC-SHA256 user defined function? - AutoIt General Help and Support - AutoIt Forums (autoitscript.com)
学习一下了！谢谢
