How to use RSA in Linux kernel

Question

I am coding a module which will use RSA to encode, decode and generate keys. But I have not found any API in kernel source(I mean linux-kernel/crpyto/) about RSA.

I don't want to take the OpenSSL, or something like it, into kernel because that will take so much time.

The crypto modules expose the Linux Kernel Crypto API. RSA support is present in kernel 3.7. Though the implementation is limited to signature verification.

Sorry, but your link with text "crypto modules" and "Linux Cross Reference - crypto.h" is dead. Could you update it? – Paul Lynn Nov 22 '20 at 03:34
