Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

	<?php
	// Define a 32-byte (64 character) hexadecimal encryption key
	// Note: The same encryption key used to encrypt the data must be used to decrypt the data
	define('ENCRYPTION_KEY', 'd0a7e7997b6d5fcd55f4b5c32611b87cd923e88837b63bf2941ef819dc8ca282');

	// Encrypt Function
	function mc_encrypt($encrypt, $key){
	$encrypt = serialize($encrypt);
	$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC), MCRYPT_DEV_URANDOM);
	$key = pack('H*', $key);
