 ## Known limitations
 
 - `xchacha20-poly1305` is implemented with pure JS [`hchacha20`](https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-xchacha#section-2.2) function and `node:crypto`'s `chacha20-poly1305` on node.
-- Currently (Nov 2024), `node:crypto`'s `chacha20-poly1305` is not supported on deno and [bun](https://github.com/oven-sh/bun/issues/8072), `@noble/ciphers`'s implementation is used on both platforms instead.
-- `deno` does not support **indirect** conditional exports. If you use this library to build another library, client code of your library probably falls back to the `node:crypto` implementation and may not work properly, specifically `aes-256-gcm` (16 bytes nonce) and `chacha20-poly1305`.
