Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

This post shows an example of a BEAM process' core dump analysis to backtrack what was the root cause of its crash.

Start gdb by pointing out the BEAM executable that generated the core dump and the core dump file. Optionally, you can provide a directory with the VM's source code:

gdb erts-6.3/bin/beam.smp -core core.14747 -d /home/azureuser/otp_src_17.4/erts/emulator

gdb should tell you what caused the crash and where in code this happened:

deserat

The script:

var http = require('http')
var fs = require('fs')


http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'})
  res.end("hello world")
}).listen(3000);

#include<stdio.h>

main()
{
    printf("Hello World");
}

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
