Is it possible for a kernel program to utilize encryption algorithms, such as RSA?

Is it possible for a kernel program to utilize encryption algorithms, such as RSA?
If possible, please tell me how to do it

The issue names no files, tests, or entry points; it asks whether a kernel program can use RSA and requests instructions. First identify the relevant kernel/BPF cryptography constraints and project scope, then clarify whether the desired outcome is documentation or an implementation before defining what done means.
