语法说明

CREATE ENCRYPT RULE encryptRuleDefinition [, encryptRuleDefinition] ...

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

参数解释

名称 数据类型 说明
tableName IDENTIFIER 表名称
columnName IDENTIFIER 逻辑数据列名称
cipherColumnName IDENTIFIER 加密数据列名称
encryptAlgorithmType STRING 加密算法类型名称

注意事项

  • PLAIN 指定明文数据列，CIPHER 指定密文数据列；
  • encryptAlgorithmType 指定加密算法类型，请参考 加密算法；
  • 重复的 tableName 将无法被创建；

示例

),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 (
