Is it possible to check a sign.or generate a key with openssl in appinv?

hi there

Is it possible to check a signature, encrypt something or generate a key with openssl in appinventor?

I'm also not sure if openssl is part of android (because its a linux i hope so)
and then i'm not sure if its reachable from inside appinventor.

I know the scope of the question could be far beyond the target group for appinventor but maybe somebody has knowledge or an idea...

Thanks in advance.

You could try this:

Terminal Extension

but it will depend on openssl being installed on the device.

You might also try Termux

Although it looks promising i'm at the moment not able to access my freshly compiled openssl (edit: using Terminal extension )
Not in Documents (shared) and not in the Assets.
More to come...
