For the WinCNG backend:

This would be great in that I'd have one less open source library (openssl)
to maintain.

I did look into this a bit but came up with too many questions:

Going through openssl.h to see what needed to be done, the hashes were
pretty simple except that LIBSSH2_HMAC_RIPEMD is not supported by WinCNG.

Supporting encryption/signing was less clear to me.

The following are also not supported by WinCNG:
LIBSSH2_AES_CTR
LIBSSH2_BLOWFISH
LIBSSH2_CAST

Modes WinCNG supports for AES:
- ECB
- CBC
- CFB
- CCM
- GCM

Not sure what _libssh2_bn would map to.

My purpose for using libssh2 is to implement SFTP. What does WinCNG need to
provide in order for SFTP to be fully implemented?

Can you summerize for us what the outstanding issues/patches are?
