This section contains the following topics: Creating a Table with an Encrypted Column. create trigger IT1 on Customers instead of insert as begin insert into encr_Customers (name,SSN) select name, EncryptByAsymKey(AsymKey_ID(' AsymKey'),SSN) from inserted end GO. DECRYPT_STRING functions for encryption and decryption, as well as with the KEYS group of key- and keyset-related functions. We can also specify which algorithm we want to use for encryption. Use randomized encryption if the column is not used for grouping and searching. This type of encryption can be used in views, and when one common password is used. We can even alter the table to add encrypted column and yes more than one column of the same table can be encrypted as well. ToString() ' Create an encrypted copy of the file Encrypt(filepath, newFilepath, encryptionKey) ' ADDED JUST FOR TESTING: Create a decrypted copy of the encrypted file Decrypt(newFilepath, newFilepath. Any other data type like a DATE, for example to encrypt a birthdate, you have to explicitly convert to a binary value first. Column level encryption means that all values in a given column are encrypted with the same password. Would like to move all employees sensitive data into a separate table and have the columns there set as encrypted columns. It also allows you to add the new column after an existing column using the AFTER existing_column clause. SQL Server 2012 Data Types Reference This SQL Server 2012 specific sheet was extracted from the orginal (all versions) 'SQL Server Data Types Reference' article. DecryptByPassphrase is used to decrypt the encrypted column.
