【问题描述】:
我的本地计算机中存储了一个加密文件。我解密文件,将解密的数据作为流获取,并尝试将其转换为字符串。以下是我的代码,但我总是将文本设为空。
private void Decrypt(string inputFilePath, string outputfilePath)
{
string EncryptionKey = "MAKV2SPBNI99212";
using (Aes encryptor = Aes.Create())
{
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey,
new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d,
0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
using (FileStream fsInput = new FileStream(inputFilePath, FileMode.Open))
{
using (CryptoStream cs = new CryptoStream(fsInput,
encryptor.CreateDecryptor(), CryptoStreamMode.Read))
{
using (Stream s = new MemoryStream())
{
int data;
while ((data = cs.ReadByte()) != -1)
{
s.WriteByte((byte)data);
}
StreamReader reader = new StreamReader(s);
string text = reader.ReadToEnd();
}
}
}
}
}
