// Generate a new identity for Alice:

// You can use HybridRecipient::fromString(/* age public key goes here */); to load a public key
// For a runnable example, we generate Bob's on-the-fly:
$bobSecret = HybridIdentity::generate(); 
$bob = $bobSecret->getRecipient();

// Sample encryption:
$aliceToBob = Age::encrypt('hello bob', [$bob]);
// Example decryption:
$bobReads = Age::decrypt($aliceToBob, [$bobSecret]);
var_dump($bobReads); // string(9) "hello bob"

// With optional ASCII armor:
$bobToAlice = Age::encryptArmored('hi alice!', [$alice->getRecipient()]);
$aliceReads = Age::decrypt($bobToAlice, [$alice]);
var_dump($aliceReads); // string(9) "hi alice!"
