Its value is generated by encrypting TRANS_ENCRYPT_SAMPLE_STRING using a database secret key. The ciphertext is used to check whether the DEK obtained during secondary startup is correct. If it is incorrect, database nodes will not be started.

CREATE COLUMN ENCRYPTION KEY Function CREATE COLUMN ENCRYPTION KEY creates a CEK that can be used to encrypt a specified column in a table. Precautions This syntax is specific to a fully-encrypted database. When using gsql to connect to a database server, you need to use the -C parameter

Its value is generated by encrypting TRANS_ENCRYPT_SAMPLE_STRING using a database secret key. The ciphertext is used to check whether the DEK obtained during secondary startup is correct. If the DEK is incorrect, CNs and DNs reject the startup.

AK/SK-based authentication: Requests are authenticated by encrypting the request body using an AK/SK pair. Authentication using AK/SK is recommended because it is more secure than authentication using tokens. Token Authentication The validity period of a token is 24 hours.
