1.java测试加密代码：
AES和HEX加密及解密工具类：
/**
* AES加解密字符串工具类
*/
public class AesEncrypt {
public static void main(String[] args) {
String aes_en = aes_encrypt("AES工具1@!","123456");
System.out.println("AES加密："+aes_en);
String aes_de = aes_decrypt("54faa6635e17933f3e4e33442e040a37","123456");
System.out.println("AES解密："+aes_de);
}
/**

* @param content 加密明文
* @param strKey 加密key
* @return
*/

//初始化为加密模式的密码器
cipher.init(Cipher.ENCRYPT_MODE, key);
//获取utf-8字符集加密内容字节数组
byte[] cleartext = content.getBytes("UTF-8");
//使用初始的加密模式密码器，对加密内容加密
byte[] ciphertextBytes = cipher.doFinal(cleartext);
//返回AES加密内容字符串
return new String(Hex.encodeHex(ciphertextBytes));
} catch (UnsupportedEncodingException e) {

} catch (NoSuchAlgorithmException e) {

} catch (NoSuchPaddingException e) {

} catch (InvalidKeyException e) {

}
/**

* @param key

*/
public static SecretKeySpec generateMySQLAESKey(final String key, final

{
try {

//根据字节数组生成AES密钥Key

}
}
2.数据库测试加密函数：
Hex（加密）、Unhex（解密）、AES_ENCRYPT（加密）、AES_DECRYPT（解密）
#查看
select HEX(AES_ENCRYPT('123456','11')) AS encrypt; #查看加密值
SELECT AES_DECRYPT(UNHEX('37793CE97D52B3C802B7319852115A4E'), '11') AS jieMi; #查看解密值
#新增==>加密
insert into user(name, encrypt_name) values('加密@1！',HEX(AES_ENCRYPT('加密@1！','123456')));
#查询==>解密
select name, AES_DECRYPT(UNHEX(encrypt_name), '123456') AS en_name from user;
#测试1：可以，不过会出现乱码==>测试成功
CREATE TABLE t_encrypt_1 (encrypt_1 varbinary(16), encrypt_2 binary(16), encrypt_3 blob);
INSERT INTO t_encrypt_1 VALUES (AES_ENCRYPT('明文1', 'key'), AES_ENCRYPT('明文2', 'key'), AES_ENCRYPT('明文3', 'key'));
SELECT AES_DECRYPT(encrypt_1, 'key'), AES_DECRYPT(encrypt_2, 'key'), AES_DECRYPT(encrypt_3, 'key') FROM t_encrypt_1;
#测试2：可以==>测试成功（推荐使用）
CREATE TABLE t_encrypt_2(encrypt2 char(32));
INSERT INTO t_encrypt_2 VALUES (HEX(AES_ENCRYPT('test2', 'key2')));
SELECT AES_DECRYPT(UNHEX(encrypt2), 'key2') FROM t_encrypt_2;
#测试3：可以（创建和添加时，做处理）==>测试成功
CREATE TABLE t_encrypt_3(encrypt3 varchar(32)) CHARSET latin1;
INSERT INTO t_encrypt_3 SELECT AES_ENCRYPT('text3', 'key3');
SELECT AES_DECRYPT(encrypt3, 'key3') FROM t_encrypt_3;
