Unity 2019的加密方式是使用了一种名为Offset的简单加密算法。具体实现代码如下:
```csharp
public static string EncryptOffset(string input, int offset)
{
char[] output = new char[input.Length];
for (int i = 0; i < input.Length; i++)
{
char c = input[i];
if (char.IsLetter(c))
{
char offsetChar = char.IsUpper(c) ? 'A' : 'a';
output[i] = (char)(((c + offset - offsetChar) % 26) + offsetChar);
}
else
{
output[i] = c;
}
}
return new string(output);
}
public static string DecryptOffset(string input, int offset)
{
char[] output = new char[input.Length];
for (int i = 0; i < input.Length; i++)
{
char c = input[i];
if (char.IsLetter(c))
{
char offsetChar = char.IsUpper(c) ? 'A' : 'a';
output[i] = (char)(((c - offset - offsetChar + 26) % 26) + offsetChar);
}
else
{
output[i] = c;
}
}
return new string(output);
}
```
使用示例:
```csharp
string input = "Hello, world!";
int offset = 3;
string encrypted = EncryptOffset(input, offset);
string decrypted = DecryptOffset(encrypted, offset);
Debug.Log("Input: " + input);
Debug.Log("Encrypted: " + encrypted);
Debug.Log("Decrypted: " + decrypted);
```
输出结果:
```
Input: Hello, world!
Encrypted: Khoor, zruog!
Decrypted: Hello, world!
```
注:Offset加密算法是一种非常简单的加密算法,它不具备高强度的安全性,仅适用于简单的加密需求。在实际开发中,建议使用更加安全、可靠的加密算法,例如AES、RSA等。
