Hello, 

 

I need some information related to ATECC508A.

 

I want to generate some random numbers using the "0x1B" command and print the same.

 

Any have any idea what is "Read/Write" commands that I can use to send to the crypto chip over I2C?

It's compatible with the ATSHA204A.

What information, exactly, do you need?

 

Google[1] quickly finds:

 

Datasheet: http://ww1.microchip.com/downloa...

 

Breakout board: https://www.sparkfun.com/product...

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

Thank you for your support...

 

Can I use this chip (ATECC508A) to encrypt and decrypt the data using the private and public keys?

 

Yes, I know about generating a digital signature of the data using a private key and verify it using the public key.

But, I would like to encrypt the data using a public key and decrypt the same using a private key using the crypto chip ATECC508A.

 

Is that possible?

 

If yes, How?

 

Is there any ATECC508A command to do that??
