Yoko.Tool.Security 1.0.0

常用的加密算法的封装，降低加密解密的使用复杂度

• 目前有的算法:AES,DES,RC4,RSA,SM2,SM3,SM4

• 支持 RSA XML 结构的 SecurityKey 和 Base64 格式的互转

• 本库不是去实现加密算法,而是基于.Net 提供的接口封装,为了方便使用

• 若是遇到了解密乱码，就在主项目中添加 System.Text.Encoding.CodePages 库，然后注册

  var builder = WebApplication.CreateBuilder(args);
  System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);

RSA

// XML私钥转换为Base64格式

//生成密钥对

// 2. 使用公钥进行加密
byte[] encryptedData = Sm2Crypt.Encrypt(publicKey, data);
Console.WriteLine("加密后的数据: " + Convert.ToBase64String(encryptedData));

// 3. 使用私钥进行解密
byte[] decryptedData = Sm2Crypt.Decrypt(privateKey, encryptedData);
Console.WriteLine("解密后的数据: " + Encoding.UTF8.GetString(decryptedData));

// 4. 使用私钥签名
byte[] signature = Sm2Crypt.Signature(privateKey, data);

// 5. 使用公钥验签
bool isVerified = Sm2Crypt.Verify(publicKey, data, signature);
