How to use CAAM RSA driver in imx6ul?

wayneshih — Tue, 18 Aug 2020 07:10:20 GMT

Hi,

I'm using imx6ulevk YOCTO sumo linux kernel L4.14.98-2.3.1.

I have some problem of accessing CAAM driver.

As far as I know, there are only two ways to access CAAM driver, one is by Cryptodev and the other is AF_ALG.

I successfully implement the symmetric cipher (e.g DES, 3DES, AES) and hashing scheme (e.g MD5, sha-1, sha256 etc) by AF_ALG framwork.

But I don't know how to implement RSA (asymmetric cipher) by either Cryptodev and AF_ALG.

if anyone have good idea to solve it?
