size-l
Estimated task size: large (2w+)
Suggested enhancement
Add support for extended versions of ChaCha20 and ChaCha20-Poly1305.
I submitted a PR with it #6556
Justification
It is well known the potential issues ChaCha20 may show due to short nonce (12 bytes). eXtended ChaCha20 (XChaCha20) aims at solving it by doubling the nonce and introducing minor changes to ChaCha20.
