求在unicloud上实现RSA4096解密的代码。

虚渺 (作者)

crypto好像有，但怎样引用？这第一句就出错了：const { generateKeyPairSync } = require('crypto');

回复 DCloud_uniCloud_WYQ: 用const crypto = require('crypto');就可以。不过后面不会用了，大神有没有参考资料？

我想实现就是提交一个rsa4096加密的字符串，返回解密结果；也就是说函数只需要解密，私匙直接放在函数里面。

你好，我用的测试代码如下：

'use strict';

exports.main = async (event, context) => {

var reqData=event.queryStringParameters;

if(reqData==null || reqData.msg==null) return "";

var pKey="-----BEGIN RSA PUBLIC KEY-----"+  

         "MIICCgKCAgEAxrgtuFBZsjDHjiDx4EiLK3Jh/tyl2PVtcpdb9jhCeHAhEXcAds7E"+

         "-----END RSA PUBLIC KEY-----";  

const crypto = require('crypto');  

if(!crypto)return "";  

const encrypted=crypto.publicEncrypt(pKey,Buffer.from(reqData.msg));  



return encrypted.toString("base64");  

};

执行后提示

Error: error:0906D06C:PEM routines:PEM_read_bio:no start line Error: error:0906D06C:PEM routines:PEM_read_bio:no start line at Object.publicEncrypt (crypto.js:390:12) at Object.exports.main (/var/user/__index.js:19:25) at y (/var/user/index.js:1:8617) at EventHandler.exports.main [as realHandler] (/var/user/index.js:1:9854) at EventHandler.handle (/var/runtime/node8/bootstrap.js:427:28) at invoke (/var/runtime/node8/bootstrap.js:225:22) at Timeout.setTimeout [as _onTimeout] (/var/runtime/node8/bootstrap.js:150:9) at ontimeout (timers.js:475:11) at tryOnTimeout (timers.js:310:5) at Timer.listOnTimeout (timers.js:270:5)

我估计是public key格式问题，但不知道正确应该怎样，请大神指点迷津。

谢谢大神。加密后问题又来了，解密时提示error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong。
