The nRF52832 has some cryptographic support, essentially what is needed for BLE security. That includes a RNG peripheral, and AES CCM peripheral. There is also a AES ECB peripheral. There are not many other security specific features of the nRF52832. You can see the product specification for details. When it comes to software, the nRF5 SDK has support for many crypto algorithms via the nrf_crypto library, which relies on various software implementations for common crypto algorithms. You also have nrf_security in the nRF Connect SDK if using that.
If you need more hardware security features, such as a key management unit and/or separations of secure and non-secure regions, I suggest you look into the nRF5340 instead.
If this does not answer the question, then please elaborate. Also please clarify the question about "test utility features".
The nRF HW and SDKs support all BLE security features. But if you need an introduction to those then I think it is best to start with the general concepts before digging into the nRF specifics. Digikey has a good intro text on BLE security here. For BLE mesh you could start with this overview.
