Cryptographic Library for STM32 MCUs certified according to US Security Standards

Question asked by Amel N Employee on Jul 14, 2016


The cryptographic library for STM32 microcontrollers is certified according to the US Cryptographic Algorithm Validation Program (CAVP).



An extension to the STM32Cube software package, the X-CUBE-CRYPTOLIB library is ready for use in security-conscious STM32-based applications.
It includes all the major security algorithms for encryption, hashing, message authentication, and digital signing.

The approved algorithms are AES (validation number 3971), RSA (2036), ECDSA (874), SHS (3275), DRBG (1165) and HMAC (2589).
Full details are available online at the NIST CSRC Algorithm Validation Lists web page.
X-CUBE-CRYPTOLIB contains many further algorithms, including DES, TripleDES, MD5, ECC with key generation, ChaCha20, Poly1305, Curve25519 and others.

The X-CUBE-CRYPTOLIB for STM32 is available free of charge under the terms of ST’s Software License Agreement (SLA0048).
