(asymmetric) Key Pair Generation - secure storage: HOW TO

# SDK: DA1468x_DA15xxx_SDK_1.0.14.1081

Hi,

just wanted to understand:

1) Whether or not is possible to generate through the SDK a key pair (priv, pub).

2) Moreover it should be useful to understand how (if possible) to securely store the private one.

Please provide sample code reference, if any.

Thank you in advance for your support

regards

aa

Hi nhan.ngodinh,

Hi nhan.ngodinh,

In DA1468x_DA15xxx_SDK_1.0.14.1081\sdk\interfaces\crypto path of SDK folder, you could find some implementations and APIs for creating Public Keys, ECDH etc. I would highly suggest you to read first the datasheet in order to understand how the ECC works. However, be aware that we don’t have any software example on that.

Thanks, PM_Dialog

Hi,

Hi,

I start to think there is not mature code for managing cyber sec stuff.

As you can see I already opened a thread named "(HW) ECDH (curve25519) from SDK vs. (external) libsodium: shared secret problem" where your support team did not find a solution by now. And it is about the code you mentioned into interfaces/crypto...

Given the ECDH code is probably bugged at the moment I do not have a way to generate PUB and PRIV keys.

Please try to answer the second question pointing me out how to use the SECURE STORAGE if any (sample code for this?).

thank you for your support.

Hi nhan.ngodinh,

Hi nhan.ngodinh,

Apologies for the delay, but I have already created an internal ticket for your queries, and we are working on that, so I will get back to you as soon as possible.

Thanks, PM_Dialog
