CREATE ENCRYPT RULE

描述

CREATE ENCRYPT RULE 语法用于创建数据加密规则

语法定义

CreateEncryptRule ::=
  'CREATE' 'ENCRYPT' 'RULE' encryptDefinition ( ',' encryptDefinition )*

encryptDefinition ::=
  tableName '(' 'COLUMNS' '(' columnDefinition ( ',' columnDefinition )*  ')' ',' 'QUERY_WITH_CIPHER_COLUMN' '=' queryWithCipherColumn ')'

columnDefinition ::=
    'NAME' '=' columnName ',' ( 'PLAIN' '=' plainColumnName )? 'CIPHER' '=' cipherColumnName ','  'TYPE' '(' 'NAME' '=' encryptAlgorithmType ( ',' 'PROPERTIES' '(' 'key' '=' 'value' ( ',' 'key' '=' 'value' )* ')' )? ')'

tableName ::=
  identifier

queryWithCipherColumn ::=
  identifier

columnName ::=
  identifier

plainColumnName ::=
  identifier

cipherColumnName ::=
  identifier

encryptAlgorithmType ::=
  identifier

补充说明

  • 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

创建数据加密规则

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);
