Here is a little proxy server setup to handle github webhooks: require('dotenv').config(); var http = require('http'); var createHandler = require('github-webhook-handler'); var handler = createHandler({ path: '/webhook', secret: process.env.GIT_WEBHOOK_SECRET }); http .createServer(function(req, res) { handler(req, res, function(err) { res.statusCode = 404; res.end('no such location'); }); }) .listen(8080); handler.on('error', function(err) { console.error('Error:', err.message); }); handler.on('push', function(event) { console.log( 'Received a push event for %s to %s', event.payload

Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 4 years ago . How can I encode a string using HMAC SHA256 algorithm? I went through OpenSSL library but didn't find anything valuable. Your suggestions? Jeffrey Hantin HMAC and SHA256 are separate components in OpenSSL, you'll need to glue them together yourself. (Note that this uses the shorthand methods for doing everything in one shot with monolithic buffers; incremental

I have issues with crypto module while upgrading my node version. The created HMAC depends on the version of node. You'll find below the piece of code that reproduces the problem. If I encode my key as BASE64 (or any) the HMAC does not depends on node.js version. If I encode it as binary, the HMAC is different if I change my node.js version. [EDIT] according to Why crypto.createHash returns different output in new version? I have added the encoding when calling the update function code snippet "use strict"; const crypto = require('crypto'); console.log(process.version); let key =

First thing I have to mention is I'm really really new to Lua and please be patient if you think my question is too dumb Here is my requirement I need to use HMAC-sha256 for Lightroom plugin development as I'm using that for security. I was trying to use this but with no luck https://code.google.com/p/lua-files/wiki/hmac These are the steps I followed Got the code of https://code.google.com/p/lua-files/source/browse/hmac.lua and saved as 'hmac.lua' file in my plugin directory Got the code from this https://code.google.com/p/lua-files/source/browse/sha2.lua and saved as 'sha2.lua' file Now in

一、hashlib模块 1.1 hash是什么 hash是一种算法（Python3.版本里使用hashlib模块代替了md5模块和sha模块，主要提供 SHA1、SHA224、SHA256、SHA384、SHA512、MD5 算法），该算法接受传入的内容，经过运算得到一串hash值。 hash算法其实可以看成如下图所示的一座工厂，工厂接收你送来的原材料，经过加工返回的产品就是hash值 import hashlib m = hashlib.md5() m.update('hello'.encode('utf8')) print(m.hexdigest()) 5d41402abc4b2a76b9719d911017c592 m.update('hash'.encode('utf8')) print(m.hexdigest()) 97fa850988687b8ceb12d773347f7712 m2 = hashlib.md5() m2.update('hellohash'.encode('utf8')) print(m2.hexdigest()) 97fa850988687b8ceb12d773347f7712 m3 = hashlib.md5() m3.update('hello'.encode('utf8')) print(m3.hexdigest())
