Actually, encrypted columns that depend on CEKs cannot be deleted. Examples 1 2 3 4 -- Delete a CEK. gaussdb=# DROP COLUMN ENCRYPTION KEY ImgCEK CASCADE; ERROR: cannot drop column setting: imgcek cascadely because encrypted column depend on it.

When you create a foreign table, the AK value is encrypted and saved to the metadata table of the database.

Setting suggestion: If indexes of all encrypted tables need to be encrypted, enable this parameter. You do not need to manually set indexes to encrypted indexes.

The encrypted CMKs are different from those specified before RR encryption. SM algorithm constraints: SM2, SM3, and SM4 are Chinese national cryptography standards. To avoid legal risks, these algorithms must be used together.
The encrypted CMKs are different from those specified before RR encryption. The constraints of using SM cryptographic algorithms are as follows: SM2, SM3, and SM4 are Chinese cryptographic algorithms. To avoid legal risks, these algorithms must be used together.

If the password string has already been encrypted in the SHA256 format, it is stored encrypted as it was, regardless of whether ENCRYPTED or UNENCRYPTED is specified (since the system cannot decrypt the specified encrypted password string).
