An encrypted PGP message consists of the following parts: Session key (encrypted symmetric key or public key) of the message Data encrypted using the session key For symmetric key (password) encryption: The key is encrypted using the String2Key (S2K) algorithm, which is like a slowed
Currently, the following types of data can be encrypted: numerals supported in the database; character type; RAW in binary type; and DATE, TIMESTAMP, and SMALLDATETIME in date/time type.
Encrypted connection Whether to encrypt the connection. Not encrypted Privacy level Privacy level Organizational Figure 21 Adding gateway information Confirm the parameter settings and click Create. The newly created connection is displayed in the gateway list.
GaussDB(DWS) uses the new CEK plaintext to encrypt the DEK and saves the encrypted DEK ciphertext. Use the CMK to encrypt the new CEK plaintext and import the encrypted CEK ciphertext to GaussDB(DWS).
In stream ciphers, encryption and decryption parties use same pseudo-random encrypted data stream as keys, and plaintext data is sequentially encrypted by these keys. In practice, data is encrypted one bit at a time using an XOR operation.

If the password is encrypted using SHA256, it will be stored as it is, regardless of whether it is specified as ENCRYPTED or UNENCRYPTED. This is because the system cannot decrypt the specified encrypted password.
Even the system administrator cannot do this unless this column is true. userepl boolean - User can initiate streaming replication and put the system in and out of backup mode. passwd Text - Password (possibly encrypted); null if none.
If the password is encrypted using SHA256, it will be stored as it is, regardless of whether it is specified as ENCRYPTED or UNENCRYPTED. This is because the system cannot decrypt the specified encrypted password.
The password is stored in ciphertext encrypted by MD5 and SHA256. 2 indicates that passwords are encrypted using SHA-256. The password is encrypted using SHA256. 1 Retry and lock password_lock_time Specifies the duration for a locked account to be automatically unlocked.
The keystr used for decryption must be the same as that used for encryption. gs_encrypt_aes128(encryptstr,keystr) Encrypts encryptstr strings using keystr as the key and returns encrypted strings.
It is not available for other users. userepl boolean Whether the user has the permission to duplicate data streams passwd Text Encrypted user password.
When you create a foreign table, its AK value is encrypted and saved to the metadata table of the database.

If the password is encrypted using SHA256, it will be stored as it is, regardless of whether it is specified as ENCRYPTED or UNENCRYPTED. This is because the system cannot decrypt the specified encrypted password.
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.
that passwords are encrypted with SHA-256.
When you create a foreign table, its AK value is encrypted and saved to the metadata table of the database.
If the password is encrypted using SHA256, it will be stored as it is, regardless of whether it is specified as ENCRYPTED or UNENCRYPTED. This is because the system cannot decrypt the specified encrypted password.
