DWSAccessKMS KMS Administrator Used to query and rotate keys in a KMS encrypted cluster. DWSAccessVPC Server Administrator If a node is faulty, the EIP is automatically migrated from the faulty node to a normal node.
The channels are not encrypted by default. NOTE: This parameter is available only for clusters with Kerberos authentication enabled.

The DEK is encrypted using the CEK and stored in the GaussDB(DWS) cluster. Keys are applied for, encrypted, and decrypted through the KMS service. The cryptographic algorithm is configured using configuration items. Currently, AES and SM4 algorithms are supported.

If Enable SSL is not selected during connecting to Data Studio, data is not encrypted by default. If the security file is damaged during the SSL connection, Data Studio cannot perform any database operations.
A positive number indicates the duration after which a locked account is automatically unlocked. 1 password_encryption_type Specifies the encryption type of user passwords. 0 indicates that passwords are encrypted with MD5. 1 indicates that passwords are encrypted with SHA-256, which

- -k, --with-key=KEY Uses gsql to decrypt imported encrypted files.
When you create a foreign table, its SK value is encrypted and saved to the metadata table of the database. chunksize Specifies the cache read by each OBS thread on a DN. Its value range is 8 to 512 in the unit of MB.
--with-encryption=AES128 Specifies that dumping data needs to be encrypted using AES128. --with-key=KEY Specifies that the key length of AES128 must be 16 bytes. --include-extensions Backs up all CREATE EXTENSION statements if the include-extensions parameter is set.
Figure 10 Configuring DataCheck You can use the command below in the tool to generate the ciphertext of src.passwd and dws.passwd. encryption.bat password After the command is executed, an encrypted file is generated in the local bin directory.
using a PGP symmetric key. 23 pgp_pub_encrypt() Used for public key encryption. 24 pgp_pub_decrypt() Decrypts a message encrypted using a PGP public key. 25 pgp_key_id() Extracts the key ID of the PGP public or private key.
