    This is a relatively simple application that simply needs to demonstrate (using Microsoft CryptoAPI in Visual Basic 6, not .NET), minimally but reliably, how to encrypt/decrypt strings as well as files using the symmetric RC4 cipher. The password should be hashed with SHA-160 (again using MS CryptoAPI) to use the hash as the cipherkey instead of the plaintext password.

All 3 tools must be written in Visual Basic 6 (_not_ VB.NET), and must use the Windows CryptoAPI functions - no other 3rd party components are to be used. App 1 - Generates a new random keypair (public + private keys) of at least 128bits in size, preferably 256bit. App 2 - Encrypts a file using a hard-coded public key App 3 - Decrypts the file using the related hard-coded private key

    I'm looking for an expert that can show me how to verify a certificate on the fly. In Windows 7 SP1 there's a new behavior that the OS comes with a minimal set of Root Certificates and when the CryptoAPI encounters a new root certificate it know how to add it to the list. I have an application that uses OpenSSL for SSL communication, I want after I get the cert to be able to use CryptoAPI to verify that the root certificate is valid, I already know how to do this using the CA root store, what I need is the ability to tell CryptoAPI to get the root certificate from the Internet and install it in the root store, just like Internet Explorer is doing.
