* 国密SM4加密算法

* 徐一杰

* 2022/10/18
|

*
|

* 调用方法：
|
||||
* import {SM4Util} from '@/utils/sm4';
|
||||
* var sm4 = new SM4Util();
|
||||
* 不使用自定义 secretKey，一般用于前端自行加解密,如果是前端加密后端解密，则需要自定义secretKey，前后端一致才能正确解密
|
||||
* sm4.encryptDefault_ECB('123456');
|
||||
* sm4.decryptDefault_ECB('123456');
|
||||
* sm4.encryptCustom_ECB('123456', 'asdfghjklmnbvcx,');
|
||||
* sm4.decryptCustom_ECB('123456', 'asdfghjklmnbvcx,');
|
||||
*
|
||||
* CBC 加密模式（更加安全），需要两个密钥
|
||||
* sm4.encryptDefault_CBC('123456');
|
||||
* sm4.decryptDefault_CBC('123456');
|
||||
* 同样可以自定义 secretKey 和 iv，需要两个密钥前后端都一致
|
||||
* sm4.encryptCustom_CBC('123456', 'asdfghjklmnbvcx,', 'mnbvcxzpoiuytre1');
|

* sm4.decryptCustom_CBC('123456', 'asdfghjklmnbvcx,', 'mnbvcxzpoiuytre1');
