ALTER ENCRYPT RULE

说明

ALTER ENCRYPT RULE 语法用于修改加密规则。

语法

AlterEncryptRule ::=
  'ALTER' 'ENCRYPT' 'RULE' encryptDefinition (',' encryptDefinition)*

encryptDefinition ::=
  ruleName '(' 'COLUMNS' '(' columnDefinition (',' columnDefinition)*  ')' ')'

columnDefinition ::=
  '(' 'NAME' '=' columnName ',' 'CIPHER' '=' cipherColumnName (',' 'ASSISTED_QUERY' '=' assistedQueryColumnName)? (',' 'LIKE_QUERY' '=' likeQueryColumnName)? ',' encryptAlgorithmDefinition (',' assistedQueryAlgorithmDefinition)? (',' likeQueryAlgorithmDefinition)? ')' 

encryptAlgorithmDefinition ::=
  'ENCRYPT_ALGORITHM' '(' 'TYPE' '(' 'NAME' '=' algorithmType (',' propertiesDefinition)? ')'

assistedQueryAlgorithmDefinition ::=
  'ASSISTED_QUERY_ALGORITHM' '(' 'TYPE' '(' 'NAME' '=' algorithmType (',' propertiesDefinition)? ')'

likeQueryAlgorithmDefinition ::=
  'LIKE_QUERY_ALGORITHM' '(' 'TYPE' '(' 'NAME' '=' algorithmType (',' propertiesDefinition)? ')'

propertiesDefinition ::=
  'PROPERTIES' '(' key '=' value (',' key '=' value)* ')'

ruleName ::=
  identifier

columnName ::=
  identifier

cipherColumnName ::=
  identifier

assistedQueryColumnName ::=
  identifier

likeQueryColumnName ::=
  identifier

algorithmType ::=
  string

key ::=
  string

value ::=
  literal

补充说明

  • CIPHER 指定密文数据列，ASSISTED_QUERY 指定辅助查询列，LIKE_QUERY 指定模糊查询列；
  • algorithmType 指定加密算法类型，请参考 加密算法；
  • 重复的 ruleName 将无法被创建。

示例

  • 修改加密规则
ALTER ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,CIPHER=user_cipher,ASSISTED_QUERY=assisted_query_user,LIKE_QUERY=like_query_user,ENCRYPT_ALGORITHM(TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),ASSISTED_QUERY_ALGORITHM(TYPE(NAME='MD5')),LIKE_QUERY_ALGORITHM(TYPE(NAME='CHAR_DIGEST_LIKE'))),
(NAME=order_id,CIPHER=order_cipher,ASSISTED_QUERY=assisted_query_order,LIKE_QUERY=like_query_order,ENCRYPT_ALGORITHM(TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),ASSISTED_QUERY_ALGORITHM(TYPE(NAME='MD5')),LIKE_QUERY_ALGORITHM(TYPE(NAME='CHAR_DIGEST_LIKE')))
));
