+== AES_ENCRYPT Function
+
+The AES_ENCRYPT function encrypts a `_string_` using a specified encryption
`_key_` with the AES (Advanced Encryption Standard) algorithm and returns a
binary string.
+
+This function prevents sensitive data from being visible to the public. For
example, use the AES_ENCRYPT function to encrypt person identity number to
preserve user confidentiality.

Review comment:
Thanks Roberta, I've incorporated your comments.
SHA (SHA1), SHA2 and MD5 can be specified, I've added the following
contents, any thoughts?
This `key` can be hashed using a cryptographic hash function, such as SHA,
SHA2 and MD5.
- This example demonstrates how the AES_ENCRYPT function works with the SHA
function.
```
SELECT AES_ENCRYPT ('hello',SHA ('world')) FROM DUAL;
(EXPR)
