Someone previously posted pretty good information about the format of
CryptProtectData on MSDN. I think it should be possible to implement a
close facsimile, except that the user's credentials (password) would be
missing in Wine since there isn't any at the moment. If you have time to
do this, it would be ideal. Failing that, doing any stateless
transformation (e.g. no change at all, or xor-ing with some magic value)
would be preferrable to storing this data in the registry, if I understood
Alexandre's comments correctly.
We're trying to avoid proliferation of OpenSSL in Wine. Relying on
CryptoAPI is a safer bet.
