Tell me the use of keyword with encryption. Create a store procedure with encryption?..

Answer / Kunwar Saurabh Singh

In SQL Server, the ENCRYPTION keyword is used to encrypt data within Transact-SQL statements for security purposes.nnTo create a stored procedure with encryption, you can follow these steps:
1. First, define the function to generate an encryption key:nCREATE MASTER KEY ENCRYPTION BY PASSWORD = '<Your_Password>';
2. Next, create a symmetric key and encrypt it using the master key:nCREATE SYMMETRIC KEY MySymmetricKey WITH ALGORITHM AES_256 ENCRYPTION BY PASSWORD = '<Your_Password>';
3. Then, you can use this symmetric key to encrypt and decrypt data within your stored procedure.
4. Here's an example of a simple stored procedure that encrypts and decrypts some text using the encryption key:nCREATE PROCEDURE EncryptDecrypt @Text NVARCHAR(MAX) AS BEGIN DECLARE @EncryptedText XML; CREATE SYMMETRIC KEY MySymmetricKey FROM PASSWORD = '<Your_Password>'; OPEN XML SYMMETRIC KEY MySymmetricKey FOR ENCRYPTION BY KEY EXTERNAL 'MyCertificate' WITH ALGORITHM AES_256; SET @EncryptedText = CONVERT(XML, ENCRYPTBYKEY(@Text using MySymmetricKey)); CLOSE XML SYMMETRIC KEY MySymmetricKey; SELECT @EncryptedText AS Encrypted_Text; -- Decryption goes here END;
