Make a Android application use FIPS 140-2 valiated

Question

I have client who wants our application to use FIPS 140-2 validated cryptography. The app uses Okhttp and does some HTTPS requests. AFAIK Android uses OpenSSL C library and uses java wrapper javax/net/ssl.

Questions:

1. How to make android Application FIPS 140 -2 Complaint?

2. Is it not android at stack(OS) level should use FIPS Compliant OpenSSL, hence all app are default FIPS 140 -2 Compliant?

3. Or our app should use FIPS 140-2 validated cryptography and make java javax/net/ssl to use it? Feasible?

4. Is there a FIPS 140-2 JCE library which can be pluggable to OKhttp?

Thanks

Answer 1

Modified OKHTTP and OKIO code to use the WolfSSL java wrappers and made it work.

Now any https requests made will go to WolfSSL layer instead of stock android BoringSSL/OpenSSL.
