Can I use Authenticated encryption with chacha20? #982

Closed fangchaooo closed 4 years ago

fangchaooo commented 4 years ago

In this document page, It introduces the Authenticated encryption that is encrypted using XSalsa20 stream cipher. But now I want to use ChaCha20 replace it. Please tell me what should I do?

It’s in the docs under the other modes. Both the IETF and original version
