A tool for generating keys using a CSPRNG.

If you have OpenSSL installed [read below](#an-alternative-openssl), as you probably do not need to install this tool.

By [AndrewCarterUK ![(Twitter)](https://camo.githubusercontent.com/6bdedfb2ec11bea20e0fb9720641fd26240465c2361f25955ca995df499d5d20/687474703a2f2f692e696d6775722e636f6d2f77577a583975422e706e67)](https://twitter.com/AndrewCarterUK)

How To Install
--------------

[](#how-to-install)

```
composer global require andrewcarteruk/cryptokey
```

Make sure you have added your global composer binary directory to the PATH in your `~/.bash_profile` (or `~/.bashrc`) file:

```
export PATH=~/.composer/vendor/bin:$PATH
```

[This blog](https://akrabat.com/global-installation-of-php-tools-with-composer/) explains the process of global composer installs in more detail.

Usage
-----

[](#usage)

```
$ cryptokey generate
bGS6lzFqvvSQ8ALbOxatm7/Vk7mLQyzqaS34Q4oR1ew=

$ cryptokey generate --format=hex
531a5187f08846a40ab6a9f9c651831bdd188e84b026804039773ef0aa51e500

$ cryptokey generate --entropy=64
ladkecOLF7RvMl/J5EGr/SMz5InfSyX+DA9CvecE/OiVFndnMqgvfLofNGO6/Gc5P1Io+eHYhcJphIRHCB9Kpg==
```

You can use the `--format` option to switch between `base64` (default) and `hex` output.

You can use the `--entropy` option to select the number of bytes of entropy. The default is 32 bytes (256 bits).

An Alternative: OpenSSL
-----------------------

[](#an-alternative-openssl)

If you have OpenSSL installed, you may find that the command(s) below are sufficient for your needs:

```
$ openssl rand -base64 32
3cDyOf7I6P4sU+ImVmIJW8k/IzGyoCACaJi+PbVY+I8=

$ openssl rand -hex 32
78a59462d4264e29be184226e7a46de0df96f97682963977fe61970b632d9faa
```

The OpenSSL command has `-base64` and `-hex` options for switching between `base64` and `hex` output.

The final argument is the number of bytes of entropy to draw. The number of bits of entropy is this number multiplied by 8.
