2.1 sounds about right. That may not be the cause of the crash.

The documentation is helpful: https://www.openssl.org/docs/man1.1.1/man3/RSA_public_encrypt.html

`flen` should be the size of `from`. So you should use `array_length_pos` with `from` instead of 
`array_length = false`.

For improved code readability you can make `padding` a Vala enum called `Padding` that binds 
`RSA_PKCS1_PADDING`, etc.

A useful tip is to look at the C code generated from the Vala. Use `--ccode` or `--save-temps` with valac to 
get the intermediate C files. If you still have troubles please post the intermediate C code generated from 
Vala.

Best wishes,
