jedisct1 / ipcrypt example snippets


use Ipcrypt\IpcryptDeterministic;

// Generate a random 16-byte key
$key = IpcryptDeterministic::generateKey();

// Example with IPv4
$ipv4 = '192.0.2.1';
$encrypted = IpcryptDeterministic::encrypt($ipv4, $key);
$decrypted = IpcryptDeterministic::decrypt($encrypted, $key);

// Example with IPv6
$ipv6 = '2001:db8::1';
$encrypted = IpcryptDeterministic::encrypt($ipv6, $key);
$decrypted = IpcryptDeterministic::decrypt($encrypted, $key);


use Ipcrypt\IpcryptNd;

// Generate a random 16-byte key
$key = IpcryptNd::generateKey();

$ip = '192.0.2.1';

// Each encryption produces a different result
$encrypted1 = IpcryptNd::encrypt($ip, $key);  // Uses random 8-byte tweak
$encrypted2 = IpcryptNd::encrypt($ip, $key);  // Different result

// Both decrypt to the same IP

$decrypted2 = IpcryptNd::decrypt($encrypted2, $key);
echo $decrypted1 === $decrypted2; // true
