当我try 使用openssl\u encrypt PHP进行加密时，我在解密数据的末尾得到了正方形空间，如附图所示
我的API响应失败，因为在由执行解密期间获得了额外字符.网侧..
如何解决此问题请帮助
C#
public static string Decrypt(String encryptedText, String VendorKey, String Token)
{
var encryptedBytes = Convert.FromBase64String(encryptedText);
return Encoding.UTF8.GetString(Decrypt(encryptedBytes, GetRijndaelManaged(VendorKey,Token)));
}
private static byte[] Decrypt(byte[] encryptedData, RijndaelManaged rijndaelManaged)
{
return rijndaelManaged.CreateDecryptor()
.TransformFinalBlock(encryptedData, 0, encryptedData.Length);
}
public static RijndaelManaged GetRijndaelManaged(String VendorKey, String Token)
{
var keyBytes = new byte[32];
var ivBytes = new byte[16];
var secretKeyBytes = Encoding.UTF8.GetBytes(VendorKey + Token);
Array.Copy(secretKeyBytes, keyBytes, Math.Min(keyBytes.Length, secretKeyBytes.Length));
var ivKeyBytes = Encoding.UTF8.GetBytes(VendorKey);
Array.Copy(ivKeyBytes, ivBytes, Math.Min(ivBytes.Length, ivKeyBytes.Length));
return new RijndaelManaged
{
Mode = CipherMode.CBC,
Padding = PaddingMode.Zeros,
KeySize = 256,
BlockSize = 128,
Key = keyBytes,
IV = ivKeyBytes
};
}
public static string Encrypt(String plainText, String VendorKey, String Token)
{
var plainBytes = Encoding.UTF8.GetBytes(plainText);
return Convert.ToBase64String(Encrypt(plainBytes, GetRijndaelManaged(VendorKey, Token)));
}
private static byte[] Encrypt(byte[] plainBytes, RijndaelManaged rijndaelManaged)
{
return rijndaelManaged.CreateEncryptor()
.TransformFinalBlock(plainBytes, 0, plainBytes.Length);
}
public static RijndaelManaged GetRijndaelManaged(String VendorKey, String Token)
{
var keyBytes = new byte[32];
var ivBytes = new byte[16];
var secretKeyBytes = Encoding.UTF8.GetBytes(VendorKey + Token);
Array.Copy(secretKeyBytes, keyBytes, Math.Min(keyBytes.Length, secretKeyBytes.Length));
var ivKeyBytes = Encoding.UTF8.GetBytes(VendorKey);
Array.Copy(ivKeyBytes, ivBytes, Math.Min(ivBytes.Length, ivKeyBytes.Length));
return new RijndaelManaged
{
Mode = CipherMode.CBC,
Padding = PaddingMode.Zeros,
KeySize = 256,
BlockSize = 128,
Key = keyBytes,
IV = ivKeyBytes
};
}
所以可以帮我解决这个问题
