Encryption

[Milan Tomic <mi...@setcce.org>]

	I'm trying to encrypt some XML using WinCAPICryptoKeyRSA():

HCRYPTPROV	win32RSACSP = 0;
CryptAcquireContext(&win32RSACSP, NULL, NULL, PROV_RSA_FULL,
CRYPT_VERIFYCONTEXT);

kek = new WinCAPICryptoKeyRSA(win32RSACSP);

	and I got "XENCAlgorithmHandlerDefault::mapURIToKey - key
inappropriate for URI" exception. Why? The rest of the code is from
cipher.cpp. I couldn't find any example how to use WinCAPICryptoKeyRSA
in encryption.

Thank you.

Milan,

Have you had a look inside xtest.cpp?

There is some code in there that *might* help.  (It also might not :<.)

In particular, have a look at "unitTestEncrypt()".  This sets up a 
WinCAPI RSA key and calls "unitTestKeyEncrypt()" to wrap an encryption key.

That particular error would indicate (for example) an RSA key passed 
into something that is expecting a Symmetric key.  E.g. the XENCCipher 
object is set to do AES encryption and gets passed an RSA key.

Cheers,
	Berin
