This is an add on to ASodium, libsodium by default does not have X448 and ED448. By combining Bouncy Castle and libsodium cryptography library, developers have now easier access to X448 and ED448.
For legacy message padding in SecureED448, kindly refer to BCASodium version 0.0.5.
This is a new add-on, do expect bugs.
If you calculate sharedsecret with X448, do make sure to use KDF to generate a 32 bytes or 256 bits symmetric encryption key as the sharedsecret by default is 448 bits or 56 bytes long
Do refer to changelog for more information.
