Here is what I try to achieve.
I tried to encrypt "dkosasih" in node.js I got 1200d4366608c5e16de242ea5aae753e.
I would've thought that it will work the same way in arduino.
Instead, when I try to encrypt the same word in arduino, I get numbers.
How do I send those number, in the form of '1200d4366608c5e16de242ea5aae753e' so that I can send them through the network and be able to be decrypted by the node.js and vice versa.
I hope I am making sense here.
