Erik de Bruin commented on FLEX-33150:
--------------------------------------
Maybe something like this does the trick (haven't run it, so mileage may vary
;-)):
public function verifyApacheFlexSDKIntegrity(localApacheFlexSDKZipFile:File,
md5HashFromApacheOrg:String):Boolean {
/**
* Note: get MD5 hash of Apache distro from:
*
http://www.apache.org/dist/incubator/flex/4.8.0-incubating/binaries/apache-flex-sdk-4.8.0-incubating-bin.zip.md5
*/
var fileAsByteArray:ByteArray = new ByteArray();
var fileStream:FileStream = new FileStream();
fileStream.open(localApacheFlexSDKZipFile, FileMode.READ);
fileStream.readBytes(fileAsByteArray);
fileStream.close();
var md5:MD5 = new MD5();
var hashAsByteArray:ByteArray = md5.hash(fileAsByteArray)
var md5HashFromLocal:String =
hashAsByteArray.readUTFBytes(hashAsByteArray.length);
return md5HashFromLocal = md5HashFromApacheOrg;
}
> Progamatically verify the MD5 hash of the downloaded Apache Flex SDK
