## AES_ENCRYPT

### description
encryption of data using the official AES
#### Syntax

`VARCHAR AES_ENCRYPT(str,key_str[,init_vector])`

### example

```
MySQL > select to_base64(AES_ENCRYPT('text','F3229A0B371ED2D9441B830D21A390C3'));
+--------------------------------+
| to_base64(aes_encrypt('text')) |
+--------------------------------+
| wr2JEDVXzL9+2XtRhgIloA==       |
+--------------------------------+
1 row in set (0.010 sec)

MySQL> set block_encryption_mode="AES_256_CBC";
Query OK, 0 rows affected (0.006 sec)

MySQL > select to_base64(AES_ENCRYPT('text','F3229A0B371ED2D9441B830D21A390C3', '0123456789'));
