[sle][security][sle15sp4][feature][manual] SLE-21227 - QA: FIPS: implement the IPSEC KDF for strongswan in openssl
OpenSSL in its master branch as a KDF (Key Derivation Function) framework.
As our FIPS strongswan certificate is only for the key derivation function we could save a lot of trouble and effort to move this functionality into openssl.
A similar thing openssl has done with the SSH KDF already, and we could do it for IPSEC too.
Upstream so far does not have it there.
