The "as" in `:as-map` is actually redundant and was there for historical
reasons that aren't relevant to a public release of this library.

Support for ChaCha20-Poly1305 was added in JDK 11 in
2018 (https://openjdk.org/jeps/329). It is a very popular alternative
to AES-GCM, due to its performance [1], and the fact that its used in
a lot of security network protocols and tools[2].

[1] Faster than AEC-GCM without hardware AES acceleration, and similar
    or better performace in multi-core machines even with AES hardware
    acceleration; see https://en.wikipedia.org/wiki/ChaCha20-Poly1305#Performance

[2] IPSec, TLS 1.2, DTLS 1.2, TLS 1.3, Wireguard, OTRv4 and multipe
    other protocols (according to https://en.wikipedia.org/wiki/ChaCha20-Poly1305#Use)
