<?php
//Initiate the keys
$result = openssl_pkey_new(array("private_key_bits" => 4096));
//Export private key to $privateKey
openssl_pkey_export($result, $privateKey);
//Get the public key
$publicKey = openssl_pkey_get_details($result)['key'];
//Prepare your plain text to encrypt
$plaintext = "Welcome To Blogdesire";
//Encrypt and export encrypted value to $encrypted_text
openssl_public_encrypt($plaintext,$encrypted_text,$publicKey);
//Print encrypted text 
echo $encrypted_text;
//Decrypt the encrypted message using the private key
openssl_private_decrypt($encrypted_text, $plaintext, $privateKey);
//Print the decrypted message
echo $plaintext;
