I can't seem to find a nice clean example of using AES 256 encryption for encrypting a file in c#
Does anyone have some sample code?
Here is the asnwer to above question
UnicodeEncoding ue = new UnicodeEncoding();
byte[] key = ue.GetBytes(password);
string cryptFile = outputFile;
using (FileStream fileCrypt = new FileStream(cryptFile, FileMode.Create))
{
using (AesManaged encrypt = new AesManaged())
{
using (CryptoStream cs = new CryptoStream(fileCrypt, encrypt.CreateEncryptor(key, key), CryptoStreamMode.Write))
{
using (FileStream fileInput = new FileStream(inputFile, FileMode.Open))
{
encrypt.KeySize = 256;
encrypt.BlockSize = 128;
int data;
while ((data = fileInput.ReadByte()) != -1)
cs.WriteByte((byte)data);
}
}
}
}
