rsa aes sm2 sm3 sm4 base64 hex cbc

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.

const LONG_TEXT = "加密，是以某种特殊的算法改变原有的信息数据，使得未授权的用户即使获得了已加密的信息，但因不知解密的方法，仍然无法了解信息的内容。 在航空学中，指利用航空摄影像片上已知的少数控制点，通过对像片测量和计算的方法在像对或整条航摄带上增加控制点的作业。"
const SHORT_TEXT = "这是一段短字符串"
