Hi, I want to enable mbed TLs library and what I saw from latest release v0.4.0 it can enable it by CONFIG_NORDIC_SECURITY_BACKEND=y in prj.conf My primary goal is to use encryption on http. Since https is not currently supported my thoughts were to use mbed TLs library to at least encrypt and decrypt payload by RSA public and private keys. My example is based on http example in SDK. The example works fine I can do HTTP GET and POST if I have CONFIG_NORDIC_SECURITY_BACKEND=n in my config.
This is my console output
15 NRF_TIMER2 Non-Secure OK
16 NRF_SAADC Non-Secure OK
17 NRF_GPIOTE1 Non-Secure OK
SPM: NS image at 0x8000
SPM: NS MSP at 0x20023eb8
SPM: NS reset vector at 0xa165
SPM: prepare to jump to Non-Secure image.

In the same project, without changing any source code if I enable TLs library by CONFIG_NORDIC_SECURITY_BACKEND=y the program hits the hard fault after bootloader jump. Below is the console output
15 NRF_TIMER2 Non-Secure OK
16 NRF_SAADC Non-Secure OK
17 NRF_GPIOTE1 Non-Secure OK

Am I missing something?.
Or is there a direct way I can use https? An example would be helpful.
