AES_ENCRYPT()andAES_DECRYPT()implement encryption and decryption of data using the official AES (Advanced Encryption Standard) algorithm, previously known as“Rijndael.”The AES standard permits various key lengths. By default these functions implement AES with a 128-bit key length. Key lengths of...
Symmetric decryption key aeskey = Base64_Decode(session_key), aeskey is 16 bytes. The initialization vector for the symmetric decryption algorithm is Base64_Decode(iv), where iv is returned by the data interface. In addition, in order to verify the validity of data, we will add data water...
TDE does real-time I/O encryption and decryption of data and log files. The encryption uses a database encryption key (DEK). The database boot record stores the key for availability during recovery. The DEK is a symmetric key, and is secured by a certificate that the server'smasterdataba...

An encryption key is a sequence that controls the operation of a cryptographic algorithm and enables the reliable encryption and decryption of data. A local or external key manager is typically used to manage the keys. With native database encryption, the database system itself encrypts the data...
A certificate, which is generated from the database master key, is used to protect the data encryption keys. The database encryption key performs the actual encryption and decryption of data on the user database. Amazon RDS backs up and manages the database master key and the TDE certificate...
Native SQL Server 2005 data encryption is restricted to the encryption and decryption of the varbinary data type. This encryption can be performed down to the cell level, meaning that the contents of each column within each row can be encrypted using different encryption keys, certificates, and ...
Data is encrypted and decrypted usingFIPS140-2compliant256-bitAESencryption. Encryption and decryption are transparent, meaning encryption and access are managed for you. Your data is secure by default and you don't need to modify your code or applications to take advantage of encryption. ...
Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext). Decryption is the process of converting ciphertext back to plaintext.
