Hi,
I tried to use RC4 algorithm provided at http://www.codeproject.com/KB/recipes/rc4csharp.aspx, but the result generated is difference with VfpEncryption

.NET = "203A7BB0530C0347082039D9583A4CF7153695A35EA6C16D92013F5A45E" (59 chars)
VFP = "9B7BB0530C0347088BD9583A4CF79C695A35EA6C16D996F5A45E" (52 chars)

// .NET

        CryptoRC4.RC4Engine rc4 = new CryptoRC4.RC4Engine();

        rc4.EncryptionKey = "1234567890";
        rc4.InClearText = "QWERTYUIOPASDFGHJKLZXCVBNM";
        bool ok = rc4.Encrypt();

        string result = ConvertToHex(rc4.CryptedText);

** VFP
strconv(Encrypt("QWERTYUIOPASDFGHJKLZXCVBNM", "1234567890", 1024), 15)

Any ides?

Thank you
