MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$EncryptedChat = $MadelineProto->messages->requestEncryption(['user_id' => InputUser, 'g_a' => 'bytes', ]);

Or, if you're into Lua:

EncryptedChat = messages.requestEncryption({user_id=InputUser, g_a='bytes', })
