+// CRYPTO_chacha_20 encrypts |in_len| bytes from |in| with the given key and
+// nonce and writes the result to |out|. If |in| and |out| alias, they must be
+// equal. The initial block counter is specified by |counter|. |in| must be
+// aligned on a block boundary.
+//
+// This function implements a 32-bit block counter as in RFC 8439. On overflow,
+// the counter wraps. Reusing a key, nonce, and block counter combination is not
+// secure, so wrapping is usually a bug in the caller. While it is possible to
+// wrap without reuse with a large initial block counter, this is not
+// recommended and may not be portable to other ChaCha20 implementations.
