All,
How can I use this code to encrypt and decrypt a file? Can I use the
filestream or does anyone have any examples of encypting a file with
3DES or AES. Any help is appreciated.

SymCryptography cryptic = new SymCryptography();
string plainText = "Daniel Sherman";
cryptic.Key = "-ldj~yriu!@*P0_^fa7431%p$+=@dJ+&";

Console.WriteLine("=============================\n ");

Console.WriteLine("Key: " + cryptic.Key + "\n");
Console.WriteLine("Using default encryption algorithm:");
string TestEnc = cryptic.Encrypt(plainText);
string TestDec = cryptic.Decrypt(TestEnc);
Console.WriteLine("Encrypted text: " + TestEnc+ "\n");
Console.WriteLine("Using RC2 algorithm:");
cryptic = new SymCryptography("rc2");
TestEnc = cryptic.Encrypt(plainText);
TestDec = cryptic.Decrypt(TestEnc);
Console.WriteLine("Encrypted text: " + TestEnc + "\n");
Console.WriteLine("Decrypted text: " + TestDec + "\n");
Console.WriteLine("Using DES algorithm:");
cryptic = new SymCryptography("DES");
TestEnc = cryptic.Encrypt(plainText);
Console.WriteLine("Encrypted text: " + TestEnc + "\n");
Console.WriteLine("Using TripleDES algorithm:");
cryptic = new SymCryptography("TripleDES");
TestEnc = cryptic.Encrypt(plainText);
Console.WriteLine("Encrypted text: " + TestEnc + "\n");
Hash hash = new Hash("SHA1");
string TestHash = hash.Encrypt(plainText);
Console.WriteLine("Using SHA1 hashing algorithm:");
Console.WriteLine("Hashed text: " + TestHash + "\n");
Console.Read();
}
}
