AES CCM encryption/decryption examples

[Lucas]

Hello,

Are there examples of AES CCM encryption/decription?

Is there a recommended procedure for generating nounces?

Are there recommended procedures for using CCM?

Thank you.

Update: I forgot to mention I am using a nrf52832.

Hi Lucas

I made an example and made it available on Github:
github.com/.../nrf52-esb-ccm-example

Please have a look at it and let me know if it can be of any help. If you have any feedback on the code I will make sure to take it into consideration :)

Best regards
Torbjørn

Hi, I checked the encryption/decryption and basing on my experience with non-simultanious-radio use crypting the 3 byte _padding for nonce part in example is misaligning. BR Macro
