Crypto Cell 310 dev on nRF9160

Question

Hi all, 
 
 I acquired the wonderful nRF9160 DevKit which embeds the ARM CryptoCell 310. 
 Rather than using the mbedTLS or TinyCrypt libs, I would like to rely on the CC310 piece of hardware to perform some cryptographic computation. 
 However, I haven't been able to find any sample code or documentation regarding interfaces, API to use. 
 
 Can someone help me, point me out some hints to start using CC310 ? 
 
 Thanks.

Nico_ID said: However, your initial release of nrf_cc310_bl seems to be dedicated to bootloader usage, with limited set of crypto features (compared to the bunch of them embedded in CC310). 
 That is correct. nrf_cc310_bl is designed to be size-optimized and intended for use cases involving the bootloader and DFU. 
 Nico_ID said: How can I access the full set of algos ? 
 We are still working on the nrf_cc310 library for the nRF9160. I believe it will be included in the next release of nRF Connect SDK (March/April timeframe). 
 Nico_ID said: Is there a lower level doc to communicate with CC310 ? the nRF doc only talks about ENABLE register. 
 No. The cryptographic functions of CC310 are only accessible by using the mentioned library, not directly via a register interface.

Nico_ID said: Is there any particular reason to justify that the CC310 mailbox system and the associated regsiters are not public ? 
 It is not public because the CC310 registers list and CC310 source code used in the library is confidential IP(Intellectual property) owned by ARM&reg; Limited. So Nordic is not allowed to make this public.
