Thanks for following up.

I was planning to use a hardware random generator but it seem that it’s not exposed on the ARMv7 platform (need to ask R&D that work with Qualcomm).

I’m thinking of using other physical sources such as RF front end etc. to create random generation as a source. Need to look into it a bit further.

I’m using the `randombytes_internal_random_buf` that uses chacha20.

The code is the same I use I just need to provide a hardware source of randmom generation by `randombytes_getentropy`
