填充无效，解密时无法删除 [英] Padding is invalid and cannot be removed while decrypting
问题描述
我正在使用以下代码来解密文本文件。它在while（（data = cs.ReadByte（））！= -1）行上给出了填充无效且无法删除的异常。 br $>
private void Decrypt（string inputFilePath，string outputfilePath）
{
string EncryptionKey =MAKV2SPBNI99212; <使用（Aes encryptor = Aes.Create（））
$ / b
$
encryptor.Key = pdb.GetBytes（32）;
encryptor.IV = pdb.GetBytes（16）;
使用（FileStream fsInput = new FileStream（inputFilePath，FileMode.Open））
{
使用（CryptoStream cs = new CryptoStream（fsInput，encryptor.CreateDecryptor（），CryptoStreamMode.Read））
int data ;
while（（data = cs.ReadByte（））！= -1）
{
fsOutput.WriteByte（（byte）data ）;
}
}
}
}
}
}
如何解决？
I am using following code to decrypt a text file.It gives me exception on "Padding is invalid and cannot be removed" on "while ((data = cs.ReadByte()) != -1)" line.
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 (FileStream fsOutput = new FileStream(outputfilePath, FileMode.Create))
{
int data;
while ((data = cs.ReadByte()) != -1)
{
fsOutput.WriteByte((byte)data);
}
}
}
}
}
}
