我目前查到sm2加密结果是C1X+C1Y+C3+C2,其中C1X,C1Y说是32字节，但也可能少于32字节的情况，位数少了估计是这个问题，服务端解密也不知道怎么改,java一般是基于bouncycastle这个库，也不知道有没有新的可以兼容。基于openssl的话，https://xie.infoq.cn/article/9685264098848c3024593c629可以看看这个，升级一下版本，我也还没验证

@xiaopihaipanwei 我运行了 1 万次加密，复现不了位数不对的情况，如果有能复现的代码麻烦贴一下看看。

前端代码
const sm2 = require("sm-crypto").sm2;
const bizData = sm2.doEncrypt("12345abc", this.publicKey1, 1);
正常密文(210)

@changhr2013 不好意思 刚刚和前端比对了一下,发现是有概率出现加密原文开头是04的情况,所以后端判断没有加上04导致无法解密. 麻烦大佬了
