Implementation chacha20 stream cipher

[Parichay]

Hi,

I am trying to implement chacha20 stream cipher to encrypt plain text and decrypt it. In the nordic SDK example the chacha20-poly1305 authenticator implementation is given. Does NRF crypto library support only chacha20 stream cipher. If yes, can you share link to the documentation?

Another option is using libsodium library https://github.com/jedisct1/libhydrogen. I am a beginner so I need help with setuping up the library and write code based on that. Can you help with that?

Thanks.

Hi, 

Please see the nRF5 SDK v15.3.0: ChaCha-Poly. This post might help. 

For the libsodium library, it is beyond our support. You should contact with the developers.
