always-encrypted

问题 I was implemented the Always Encrypted and Dynamic data masking concepts in my azure SQL database on two different tables. But I have doubt like “Is it possible to apply the dynamic data masking on already encrypted column in same table”. I tried the above scenario it gives error like “The data type of column 'SSN' does not support data masking function 'partial'.”. I run the below query for applying the masking on already encrypted column. ALTER TABLE [dbo].[CustomerTables] ALTER COLUMN [SSN

问题 .NET Framework Ver = 4.6.2 , Database = SQL Server 2016 App Type = Windows Service We are working on the "Always Encrypted" feature in the SQL 2016 db to perform the encryption on certain customer data columns. Our web application is built in the ASP.NET MVC architecture and is working fine with this new feature. We have copied and imported the certificate from the database server over to the IIS web-server. And the web-application is working smoothly. But when we try to access the DB from a

问题 Once we started to write data into an encrypted table, we noticed problems once we tried to read encrypted data. Symptoms are identical to the ones described HERE Here is a little bit of a background. We have a web app, which writes client information to a "client" table in the SQL Server database. As a transition solution, we created additional table client_enc and updated our app to write to both tables: original one and an encrypted one. We have 4 instances of our web app, hosted on the

问题 I have a scenario where i need to have literals(hard coded strings) inside proc used against "Always Encrypted" columns, Since this fails with the following error, Operand type clash: varchar is incompatible with nvarchar(20) encrypted with (encryption_type = 'DETERMINISTIC', encryption_algorithm_name = 'AEAD_AES_256_CBC_HMAC_SHA_256', column_encryption_key_name = 'CEK_Auto4', column_encryption_key_database_name = 'DBName') I am trying to do Parameterization for Always Encrypted within the

问题 I have created a table using: create table dbo.employee(firstname nvarchar(100) null,lastname nvarchar(100) null) Inserted some sample data using: insert into dbo.employee values('Sachin','Tendulkar') insert into dbo.employee values('Rohit','Sharma') insert into dbo.employee values('Virendra','Sehwag') insert into dbo.employee values('Irfan','Pathan') Then I used always encrypted wizard to encrypt both columns of this table using SSMS v17. And now I am trying to concatenate firstname with

问题 I am getting a SqlException : Operand type clash: varchar is incompatible with varchar(50) encrypted with (encryption_type = 'DETERMINISTIC', encryption_algorithm_name = 'AEAD_AES_256_CBC_HMAC_SHA_256', column_encryption_key_name = 'CEK_Auto1', column_encryption_key_database_name = 'PB') collation_name = 'SQL_Latin1_General_CP1_CI_AS'\r\nIncorrect parameter encryption metadata was received from the client.

问题 I just installed SQL 2016 Standard Edition because I wanted to use the 'Always Encrypted' feature. However, when I tried to created a Column Master Key under Security->Always Encrypted Keys->Column Master Key, I got the following error: productversion: 13.0.160.5, productlevel:RTM, edition:Standard Edition 64bit Any ideas? Thanks! 回答1: I was having the same issue. I fixed it by updating to Sql Server 2016 SP1 from Sql Server 2016. Previously @@version was: Microsoft SQL Server 2016 (RTM-GDR)

问题 I have encrypted few columns in sql 2016 table using column encryption. Now I want to Insert data into that table. I tried creating a stored procedure and executing that procedure with parameters but I am getting following error. Encryption scheme mismatch for columns/variables '@lastName'. The encryption scheme for the columns/variables is (encryption_type = 'PLAINTEXT') and the expression near line '0' expects it to be (encryption_type = 'DETERMINISTIC', encryption_algorithm_name = 'AEAD

问题 I'm created a client application that do all the encrypt and decrypt values using Always Encryption. I've used Azure Key vault to store my Keys. I've followed this. It worked for me fine with the hardcoded query (INSERT INTO ....) But when I tried with a stored procedure, it didn't work. I've already referred to this Stack Post. But the solutions/answer didn't solve my problems unfortunately. So I've decided to open a new question. This is my C# code SqlCommand cmd = _sqlconn.CreateCommand();

问题 Currently I'm using SQL Server 2016 to make benefit of Always Encrypted feature. There are a couple of columns that I should encrypt. I've encrypted those columns with SQL Server. NHibernate can easily read data from SQL Server but when it tries to insert data in the DB it will throw an exeption like below: Operand type clash: nvarchar(4000) encrypted with (encryption_type = 'DETERMINISTIC', encryption_algorithm_name = 'AEAD_AES_256_CBC_HMAC_SHA_256', column_encryption_key_name = 'CEK_Auto1',
