Key Vault Encryption Serializer

KeyVaultEncryptionSerializer.cs

    public class KeyVaultEncryptionSerializer : IBsonSerializer
    {
        private readonly string _elementName;
        
        public KeyVaultEncryptionSerializer(string elementName)
        {
            _elementName = elementName;
            
        }

        public object Deserialize(BsonDeserializationContext context, BsonDeserializationArgs args)
        {
            return context.Reader.ReadString();
        }

        public void Serialize(BsonSerializationContext context, BsonSerializationArgs args, object value)
        {
            //I COULD POTENTIALLY WRITE A DOCUMENT FOR EVERY ENCRYPTED NODE
            //context.Writer.WriteStartDocument();
            //context.Writer.WriteName($"{_elementName}_Encrypted");
            //context.Writer.WriteEndDocument();


            //OR I COULD SIMPLY WRITE THE ENCRYTPED VALUE
            var symmetricKey = "someKey"; //Here's where I need to read the document's CekProperty
            var encryptedValue = EncryptData(value.ToString(), symmetricKey);
            //encrypt the value using the Key obtained above. In this example, I'm simply appending the key
            //for illustration purposes
            context.Writer.WriteString(encryptedValue);
        }

        public Type ValueType => typeof(string);
    }

did you ever get this to a working solution? currently in need for an encryption attribute. bonus points if it can support azure keyvault
