Node.js x509.fingerprint 属性
x509.fingerprint是加密模块中 X509Certificate 类的内置应用程序编程接口,用于获取此证书的 SHA-1 指纹。
句法:
const x509.fingerprint
参数:此属性不接受任何参数作为参数。
返回值:此属性返回此证书的 SHA-1 指纹。
如何生成公共证书?
公共证书打开记事本并复制粘贴以下密钥并将文件保存为public-cert.pem

示例 1:
index.js
// Node.js program to demonstrate the
// x509.fingerprint function
// Importing crypto module
const {X509Certificate} = require('crypto')
// Importing fs module
const fs = require('fs')
// getting object of a PEM encoded X509 Certificate.
const x509 = new X509Certificate(fs.readFileSync('public-cert.pem'));
// getting the SHA-1 fingerprint of this certificate.
// by using x509.fingerprint function
const value = x509.fingerprint
// display the result
console.log("SHA-1 fingerprint of this certificate :- " + value)
index.js
// Node.js program to demonstrate the
// x509.fingerprint function
// Importing crypto module
const {X509Certificate} = require('crypto')
// Importing fs module
const fs = require('fs')
// display the result
console.log("SHA-1 fingerprint of this certificate :- " +
(new X509Certificate(fs.readFileSync('public-cert.pem')))
.fingerprint)
使用以下命令运行 index.js 文件。
node index.js
输出:
SHA-1 fingerprint of this certificate :-
