ef core加密存储数据，如身份证号

一、新建项目，安装nuget

<PackageReference Include="V6.EntityFrameworkCore.DataEncryption" Version="5.0.0" />

二、本示例采用：AES+256bits(Can use a 128bits, 192bits or 256bits key)

 CipherMode mode = CipherMode.CBC, PaddingMode padding = PaddingMode.PKCS7

三、使用方法

public class Demo_DataEncryption{/// <summary>/// 名称/// </summary>[StringLength(50)]public string Name { get; set; }/// <summary>/// 移动电话/// </summary>
 [StringLength(50)][Encrypted]public string TelPhone { get; set; }}

public class DatabaseContext : DbContext
{// Get key and IV from a Base64String or any other ways.// You can generate a key and IV using "AesProvider.GenerateKey()"private readonly byte[] _encryptionKey = Encoding.UTF8.GetBytes("..."); private readonly byte[] _encryptionIV = Encoding.UTF8.GetBytes("...");private readonly IEncryptionProvider _provider;public DbSet<Demo_DataEncryption> DataEncryptions { get; set; }public DatabaseContext(DbContextOptions options): base(options){this._provider = new AesProvider(this._encryptionKey, this._encryptionIV);}protected override void OnModelCreating(ModelBuilder modelBuilder){modelBuilder.UseEncryption(this._provider);}
}
