vim: build with +sodium feature
    xchacha20  XChaCha20 Cipher with Poly1305 Message Authentication
     Code.  Medium strong till strong encryption.
     Encryption is provided by the libsodium library, it
     requires Vim to be built with |+sodium|.
     It adds a seed and a message authentication code (MAC)
     to the file.  This needs at least a Vim 8.2.3022 to
     read the encrypted file.
     Encryption of swap files is not supported, therefore
     no swap file will be used when xchacha20 encryption is
     enabled.
     Encryption of undo files is not yet supported,
     therefore no undo file will currently be written.
     CURRENTLY EXPERIMENTAL: Files written with this method
     might have to be read back with the same version of
     Vim if the binary format changes later.
