Binary Base Conversion in PHP

So, I have come accorss a lot of poor PHP base conversion implementations all over the internet that are unsuitable or incapable of doing large base conversion on binary data. This really isn't a problem for most people in PHP until you start dealing with very large decimals that are sensitive to percision loss, like in cryptography. The following provides two implementations for base conversion that should be safe for large bases and binary data, for example, converting a base256 (binary string) to base85 representation and back again.

Using GMP

You can use GMP to accomplish this at the cost of converting bin<->hex two unneeded times as well as being limited to base62.

<?php
// Not bits, bytes.
$data = openssl_random_pseudo_bytes(256);
package main
import (
"errors"
"fmt"
"math/rand"
"time"
)
type Game struct {

Secure random values (in Node.js)

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

  • Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
  • Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
  • If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
  • If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Complete overview of the PHP SessionHandler life-cycle

This page provides a full overview of PHP's SessionHandler life-cycle - this was generated by a set of test-scripts, in order to provide an exact overview of when and what you can expect will be called in your custom SessionHandler implementation.

Each example is a separate script being run by a client with cookies enabled.

To the left, you can see the function being called in your script, and to the right, you can see the resulting calls being made to a custom session-handler registed using session_set_save_handler().
