Android Question B4x Using external libraries for encryption

[nickt]

Hi,

From what I have been able to glean from the forum there is an encryption library based on bouncycastle and it has been updated to 171. I need access to more than AES and RSA so my question is how to do this in the most time efficient way?

I could write a series of functions in Dart and compile a library for each platform but it isn't clear from the posts I have seen just how I would integrate it OR do I write some JAVA functions and inline them (converting to objective C for apple)

Thanks

Dart will not help.

The Encryption library is based on the native encryption SDK. Which method of encryption are you looking for?

Ideally asynchronous Ed25519 (512) for both key gen and secret key protection and 256 Xchacha20 as it's faster and a stream cipher although AES 256 would be a 2nd choice. I know both are in the bouncycastle libraries, I just don't know how to get at them from B4x (which I would much rather be using than flutter/MAUI/CodenameOne/QT etc).

Hopefully there is a workaround

Thanks

Ed25519 is not natively supported by Android. You will need to find a Java library that supports it. Once you find one you can access it using JavaObject / inline java.

Ok Thanks.
