The good thing about libsodium is that it doesn't support or implement
existing standards, which are quite archaic and brittle. And generally it
provides only 1 or 2 libsodium-specific algorithms and formats for any
particular operation, which are hard to use improperly.

The bad thing about libsodium is that [same as above].

In particular, libsodium doesn't support RSA, period. And good luck finding
any existing software, other than libsodium-derived software, that can
accept it's "sealed boxes" messages.
