例 1:
index . js
// Node.js program to demonstrate the
// x509.fingerprint256 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-256 fingerprint of this certificate.
// by using x509.fingerprint256 function
const value = x509.fingerprint256
// display the result
console.log("SHA-256 fingerprint of this certificate :- "
+ value)
使用以下命令运行 index.js 文件。
node index.js
输出:
SHA-256 fingerprint of this certificate :-
77:7B:70:8C:52:C5:C8:02:88:B3:BD:D5:1F:6C:A5:AB:78:
