Python hashlib is twice as fast as Java MessageDigest: see the related post here: http://cppsfn.co/hashlib-vs-messagedigest
public static double comparison(int desiredSize, int bufferSize){
int size = desiredSize / bufferSize * bufferSize;
byte data[] = new byte[size];
new Random().nextBytes(data);
long startTime = 0;
long endTime = 0;
int nRounds = 10;
double elapsed = 0;
for(int round = 0; round < nRounds; round++){
MessageDigest sha = MessageDigest.getInstance("SHA-256");
