How I can encrypt a message with my own session key?

["KOMATSU, Tetsuro" <Tetsuro.Komatsu () SankyoSeiki Co JP>]

I am now trying to find out how I can encrypt a message in CALG_3DES_112
by using Win32 functions such as CryptAquireContext, CryptEncrypt,
and so on.
I have to give not only the initialize vector but also the session key
to do the encryption. Which Win32 function(s) is useful to specify
my own session key ?

Thanks in advance.
