windev code：
secretKey is string= "Gu5t9xGARNpq86cd98joQYCN3*******"
srcStr is string = "GETcvm.tencentcloudapi.com/?Action=DescribeInstances&InstanceIds.0=ins-09dx96dg&Limit=20&Nonce=11886&Offset=0&Region=ap-guangzhou&SecretId=AKIDz8krbsJ5yKBZQpn74WFkmLPx3*******&Timestamp=1465185768&Version=2017-03-12"
signStr is string = Encode(HashString(HA_HMAC_SHA_160,srcStr,secretKey),encodeBASE64)
trace(signStr) //the result is "5PaiqVPaSxwQrIfjSGO8wQ+nozE="
php code：
$secretKey = 'Gu5t9xGARNpq86cd98joQYCN3*******';
$srcStr = 'GETcvm.tencentcloudapi.com/?Action=DescribeInstances&InstanceIds.0=ins-09dx96dg&Limit=20&Nonce=11886&Offset=0&Region=ap-guangzhou&SecretId=AKIDz8krbsJ5yKBZQpn74WFkmLPx3*******&Timestamp=1465185768&Version=2017-03-12';
$signStr = base64_encode(hash_hmac('sha1', $srcStr, $secretKey, true));
echo $signStr;
//the resule is "zmmjn35mikh6pM3V7sUEuX4wyYM="
the result is diffrent, and the PHP result is Official.Why??? |

It's simple: the functions Hash and Encode are two different things. Hash: the source string is unrecoverable. Encode: the source string is recoverable.

| HashString treats the input strings as a raw bytes, therefore the ANSI vs UNICODE character encoding is critical. Change the secretKey and srcStr declarations to 'ANSI String' and your code will produce the same output as the php version. |
