Implementation chacha20 stream cipher

Implementation chacha20 stream cipherhttps://devzone.nordicsemi.com/f/nordic-q-a/52138/implementation-chacha20-stream-cipherHi, 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, canen-USTelligent Community 13Mon, 16 Sep 2019 11:05:15 GMTRE: Implementation chacha20 stream cipherhttps://devzone.nordicsemi.com/thread/209797?ContentTypeID=1Mon, 16 Sep 2019 11:05:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:603e81ce-a1ef-4bf4-8586-5bba2601d135Amanda Hsieh<p>Hi, </p> <p></p> <p>Please see the <a title="Software Development Kit" href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_crypto_chacha_poly.html?resultof=%22%63%68%61%63%68%61%32%30%22%20">nRF5 SDK v15.3.0: ChaCha-Poly</a>.
