nrf_oberon crypto library¶
The nrf_oberon library contains a collection of cryptographic algorithms created by Oberon Microsystems, licensed to Nordic Semiconductor ASA for redistribution. The library provides highly optimized software for Nordic Semiconductor SoCs based on Cortex-M0, Cortex-M4, and Cortex-M33 architectures.
AES CTR, EAX, GCM
ECDH using curve NIST secp256r1
ECDSA sign and verify using curve NIST secp256r1
HKDF using SHA-256 and SHA-512
HMAC using SHA-256 and SHA-512
RSA PKCS#1 v1.5 and v2.1 (1024, 2048 bits)
The library does not require any initialization before the APIs can be used, although some APIs require calling specific initialization functions before use.
Starting from version 3.0.5, the nrf_oberon library contains a companion library that provides Mbed TLS integration for select features. This must be used with the Nordic Security Module.
