multi-crypto-js

简要说明:

​ 此工具是一个集RSA、AES、SM2、SM4为一体的算法工具,支持base64和hex两种格式的密钥、向量、签名结果以及加密结果.

​ 其中, RSA基于jsencrypt封装、AES基于Crypto-JS封装、SM2基于sm-crypto封装、SM4基于第三方开源实现封装.

​ AES、SM4算法生成的密钥和向量均为128位(base64格式或hex格式解码后的长度).

​ AES加密算法使用的是 AES/CBC/PKCS7Padding.

​ SM4加密算法使用的是 SM4/CBC/PKCS7Padding.

​ RSA加密算法使用的是 RSA/None/PKCS1Padding, 暂不支持分段加解密.

​ RSA签名算法支持MD5withRSA、SHA1withRSA、SHA256withRSA、SHA384withRSA和SHA512withRSA.

​ SM2签名算法支持SM3withSM2.

​ 此工具支持常用浏览器和微信小程序.
