Curve25519 in nRF5340

[Aslamies]

According to nRF5340 product specification https://infocenter.nordicsemi.com/topic/ps_nrf5340/cryptocell.html?cp=3_0_0_6_6_2#cc_standards,

It's CryptoCell 312 supports Curve25519.

But when I use mbedtls_ecp_curve_list(), it does not show curve25519.

I'm usning nRF5340_DK with nRF Connect SDK v.1.4.2

Hi,

You are right that CC312 supports Curve25519. However, the mbed TLS frontend currently in the nRF Connect SDK does not support it in it's API. It will be added in a future release, but is currently not available.

Hi Einar,

Any update on the support for this curve, we are seeking to use this curve. Any ETA on the support?
