Hi,

I asked because you start your first message with  "ola todos" and it's
portuguese, so, as I'm brazilian I think you was brazilian (or maybe
Portuguese) to :-)

About your english, take it easy, my english is very poor too :-)

To create a session key (simmetric) all you should do is call the function
CryptGenKey() specifing an algorithm such RC2 or RC4.

Ex:
BOOL  bOk = ::CryptGenKey(m_hCryptProvider, CALG_RC4, CRYPT_EXPORTABLE,
&m_hSessionKey);

Of course you must acquire a crypto context through function
CryptAcquireContext( ... )

People, if I have made some mistake, please, correct me.

probably i will do that, but when reading some
CAPI docs i was not be able to find the method to
create a one session key: instead i read that if
you create a RSA key pair within a container, this
key will be recorded (for ever :) until next OS
installation... arg...
