ALTER ENCRYPT RULE encryptRuleDefinition [, encryptRuleDefinition] ...

DROP ENCRYPT RULE tableName [, tableName] ...

encryptRuleDefinition:
    tableName(COLUMNS(columnDefinition [, columnDefinition] ...), QUERY_WITH_CIPHER_COLUMN=queryWithCipherColumn)

columnDefinition:
    (NAME=columnName [, PLAIN=plainColumnName] , CIPHER=cipherColumnName, encryptAlgorithm)

encryptAlgorithm:
    TYPE(NAME=encryptAlgorithmType [, PROPERTIES([algorithmProperties] )] )

algorithmProperties:
    algorithmProperty [, algorithmProperty] ...

algorithmProperty:
    key=value

Parameters Explained

name DateType Description
tableName IDENTIFIER Table name
columnName IDENTIFIER Logic column name
cipherColumnName IDENTIFIER Cipher column name
encryptAlgorithmType STRING Encryption algorithm type name

Notes

  • PLAIN specifies the plain column, CIPHER specifies the cipher column
  • encryptAlgorithmType specifies the encryption algorithm type, please refer to Encryption Algorithm
  • Duplicate tableName will not be created
  • queryWithCipherColumn support uppercase or lowercase true or false

Example

CREATE ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id, CIPHER =order_cipher,TYPE(NAME='MD5'))
), QUERY_WITH_CIPHER_COLUMN=true),
t_encrypt_2 (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id, CIPHER=order_cipher,TYPE(NAME='MD5'))
), QUERY_WITH_CIPHER_COLUMN=FALSE);

ALTER ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id,CIPHER=order_cipher,TYPE(NAME='MD5'))
), QUERY_WITH_CIPHER_COLUMN=TRUE);
