在MySQL中加密和解密字符串？

2024-04-21 05:46:03 485

要在MySQL中加密和解密，请在MySQL中使用AES_ENCRYPT()和AES_DECRYPT()-

insert into yourTableName values(AES_ENCRYPT(yourValue,yourSecretKey));

select cast(AES_DECRYPT(yourColumnName, yourSecretKey) as char) from
yourTableName;

要了解上述语法，让我们首先创建一个表-

mysql> create table demo63
−> (
−> value blob
−> );

借助insert命令将一些记录插入表中。我们在插入时正在加密-

mysql> insert into demo63 values(AES_ENCRYPT('John','PASS'));

mysql> insert into demo63 values(AES_ENCRYPT('David','PASS'));

mysql> insert into demo63 values(AES_ENCRYPT('123456','PASS'));

使用select语句显示表中的记录-

mysql> select *from demo63;

这将产生以下输出-

+------------------------------------+
| value                              |
+------------------------------------+
| 0x16D8A4F11321D761920783BF96BB8314 |
| 0x0A85099F705F21D27B0129C54C4473AA |
| 0xAB7C6D6068BC100B0F04D1C4EA068AC9 |
+------------------------------------+
3 rows in set (0.00 sec)

以下是要解密的查询-

mysql> select cast(aes_decrypt(value, 'PASS') AS char) from demo63;

这将产生以下输出-

+------------------------------------------+
| cast(aes_decrypt(value, 'PASS') AS char) |
+------------------------------------------+
| John                                     |
| David                                    |
| 123456                                   |
+------------------------------------------+
3 rows in set (0.00 sec)
