public byte[]
EncryptMyData (byte[] plainData, out byte[] encryptionKey)<-- what the mean of this???
{
encryptionKey = Guid.NewGuid().ToByteArray();
int[] scheduledKey = AcedCast5.ScheduleKey(encryptionKey);
long iv = AcedCast5.GetOrdinaryIV(scheduledKey);
byte[] result = (byte[])plainData.Clone();
AcedCast5.EncryptCBC(scheduledKey, result, 0, result.Length, iv);
AcedCast5.ClearKey(scheduledKey);
return result;
}
public byte[] DecryptMyData(byte[] encryptedData, byte[]
decryptionKey)
{
int[] scheduledKey = AcedCast5.ScheduleKey(decryptionKey);
long iv = AcedCast5.GetOrdinaryIV(scheduledKey);
byte[] result = (byte[])encryptedData.Clone();
AcedCast5.DecryptCBC(scheduledKey, result, 0, result.Length, iv);
AcedCast5.ClearKey(scheduledKey);
return result;
}
