Well I tried hashing a string or at least a set of numbers in Python and compare it with the one generated using the MD5 Library updated by Scott MacVicar on the Arduino but the results I get are differents.

Arduino Code:

#include <MD5.h> void setup() { //initialize serial Serial.begin(9600); //give it a second delay(1000); //generate the MD5 hash for our string unsigned char* hash=MD5::make_hash("hello"); //generate the digest (hex encoding) of our hash char *md5str = MD5::make_digest(hash, 16); //print it on our serial monitor Serial.println(md5str); } 

Result: 5d41402abc4b2a76b9e4080020008c00

Python Code:

from hashlib import md5 m = md5('hello').hexdigest() print m 

Result: 5d41402abc4b2a76b9719d911017c592

From what I can see in every attempt is that the difference comes at the last 14 characters. But the length of the generated hashes are the same!

What am I doing wrong?? Thanks

Edit:

I used a command from the terminal and got:

echo -n 'hello' | openssl md5 

Result: 5d41402abc4b2a76b9719d911017c592

Which makes me think that the root of the problem is in the arduino code
