只是要列出我擁有的所有信息：簡而言之，我正在尋找與 ASP Core (2.2) 和 C# MongoDB Driver (2.7) 完全（字面意思）類似的東西。這似乎是一個常見的要求，我很驚訝我找不到任何已經建成的東西。這是我到目前為止所擁有的：模型：public class Patient{ //comes from the client as XXXXXXXXX, RegEx: "([0-9]{9})" //[MongoEncrypt] public EncryptedString SocialSecurityNumber { get; set; } }屬性：[AttributeUsage(AttributeTargets.Property)]public class MongoEncryptAttribute : BsonSerializerAttribute{ public MongoEncryptAttribute() { SerializerType = typeof(MongoEncryptSerializer); }}自定義序列化器：public interface IMongoEncryptSerializer : IBsonSerializer<EncryptedString>{ }public class MongoEncryptSerializer : SerializerBase<EncryptedString>, IMongoEncryptSerializer{ private readonly string _encryptionKey; public MongoEncryptSerializer(IConfiguration configuration) { _encryptionKey = configuration.GetSection("MongoDb")["EncryptionKey"]; } public override EncryptedString Deserialize(BsonDeserializationContext context, BsonDeserializationArgs args) { var encryptedString = context.Reader.ReadString(); return AesThenHmac.SimpleDecryptWithPassword(encryptedString, _encryptionKey); } public override void Serialize(BsonSerializationContext context, BsonSerializationArgs args, EncryptedString value) { var encryptedString = AesThenHmac.SimpleEncryptWithPassword(value, _encryptionKey); context.Writer.WriteString(encryptedString); }}

我的解決方案：
模型：
public class Patient
{
//comes from the client as XXXXXXXXX, RegEx: "([0-9]{9})"
public EncryptedString SocialSecurityNumber { get; set; }
}
自定義類型：
public class EncryptedString
{
private readonly string _value;
public EncryptedString(string value)
{
_value = value;
}
public static implicit operator string(EncryptedString s)
{
return s._value;
}
public static implicit operator EncryptedString(string value)
{
if (value == null)
return null;
return new EncryptedString(value);
}
}
序列化器（使用確定性加密）：
public interface IEncryptedStringSerializer : IBsonSerializer<EncryptedString> {}
public class EncryptedStringSerializer : SerializerBase<EncryptedString>, IEncryptedStringSerializer
{
private readonly IDeterministicEncrypter _encrypter;
private readonly string _encryptionKey;
public EncryptedStringSerializer(IConfiguration configuration, IDeterministicEncrypter encrypter)
{
_encrypter = encrypter;
_encryptionKey = configuration.GetSection("MongoDb")["EncryptionKey"];
}
public override EncryptedString Deserialize(BsonDeserializationContext context, BsonDeserializationArgs args)
{
var encryptedString = context.Reader.ReadString();
return _encrypter.DecryptStringWithPassword(encryptedString, _encryptionKey);
}
public override void Serialize(BsonSerializationContext context, BsonSerializationArgs args, EncryptedString value)
{
var encryptedString = _encrypter.EncryptStringWithPassword(value, _encryptionKey);
context.Writer.WriteString(encryptedString);
}
}
注冊序列化器：
collection.AddScoped<IEncryptedStringSerializer, EncryptedStringSerializer>();
//then later...
BsonSerializer.RegisterSerializer<EncryptedString>(sp.GetService<IEncryptedStringSerializer>());
