Verify that the AES-128 is used for encrypting the local CA
    
    OpenSSL by default used very old defaults, RC2-CBC and 3DES, for
    encryption. This resulted in a credential that was unusable if
    FIPS was enabled.
    
    Both values are now hardcoded to AES-128-CBC so that it is both
    more modern and will work in all situations. This tests that
    nothing has changed.
