Security, Certificates and 3DES/RSA/OAEP

Greetings,

I am trying to build an interface into an existing system which accepts
UTF-8 encoded "messages". In these messages, there is a unencrypted base64
"key" in the header which is used to encrypt the "body" of the remainder of
the document.

How do I do simple encryption and decryption within VB.NET ? Could someone
point me any good examples for performing the following tasks:

1. Generate random 168 bit key
2. Encrypt a string using the 3DES algorithm
3. Encryption a symmetric key using the public asymmetric key using RSA
without OAEP padding (could someone explain the difference between symmetric
and asymmetric to me with respect to public/private key pairs?)

Thanks in advance for any hints and tips!

Lidle,

I think that this is good question for the newsgroup

microsoft.public.dotnet.security

It is an active newsgroup.

This does not mean you are not welcome here, however probably there are in
that newsgroup more who can help you.
