    Microsoft prevents third parties from installing un-authorized crypto
    code under CAPI by checking the signature on the code.  Under their
    export deal, they refuse to sign anyone's non-US code that does strong
    crypto.  So if you want to add your own strong crypto, you need to sign
    it with a key that the CAPI recognizes.  You could patch out Microsoft's
    key but then the Microsoft modules won't load properly.  It works
    better to patch out NSA's key with your own -- then you can load both
    your own crypto code and all the standard MS stuff.
