Has anybody tried working SHA-1 encryption algorithm using any SAM controllers?

What, specifically, are you asking about?

 

The SHA-1 algorithm itself has nothing to do with any particular hardware platform: https://en.wikipedia.org/wiki/SHA-1

 

Or are you asking about particular hardware features of some specific chip(s) ... ?

 

EDIT

 

There is a section for General Security Discussions in the IoT Community ...

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Hi awneil,

Sorry for not being specific. We were testing SHA 1 algorithm in our SAMD21 xplained board.

It has got nothing to do with the hardware, but was wondering if anybody could help me out with few of my queries.

I was wondering if we change the 5 constants (h0-h5) with some random numbers, will it affect the overall process?

assuming the receiver also knows the 5 constants used in the process.
