谢谢大佬先了。

class Rsa { /** * Encrypts text with sha256WithRSAEncryption/RSA_PKCS1_OAEP_PADDING. * Recommended Node Limits Version >= 12.9.0 (`oaepHash` was available), even it works on v10.15.0. * * @param {string} plaintext - Cleartext to encode. * @param {string|Buffer} publicCertificate - A PEM encoded public certificate. * * @returns {string} Base64-encoded ciphertext. */ static encrypt(plaintext, publicCertificate) { return crypto.publicEncrypt({ oaepHash: sha1, key: publicCertificate, padding: RSA_PKCS1_OAEP_PADDING, }, Buffer.from(plaintext, utf8)).toString(base64) } }
源码可见 https://github.com/TheNorthMemory/wechatpay-axios-plugin/blob/master/lib/rsa.js
你好，麻烦通过点击下方“反馈信息”按钮，提供出现问题的。
const nonceStr = Math.random().toString(36).slice(-10) const timestamp = (new Date().getTime() / 1000).toFixed(0) const message = `GET\n/v3/certificates\n${timestamp}\n${nonceStr}\n\n` const signature = crypto.createSign('RSA-SHA256').update(message, 'utf-8').sign(fs.readFileSync('apiclient_key.pem').toString(), 'base64')
网上有找到点相关的加密函数，但是参数密码相关的参数意思完全不懂。。
