Decrypt OpenSSL encrypted string in objective-c

Question

I have a string encrypted in PHP using following code

function encrypt($string, $publicKey)
{
    openssl_public_encrypt($string, $cryptedText, $publicKey);
    return base64_encode($cryptedText);
}
$publicKey = file_get_contents('public.crt');
$encryptedText = encrypt('Test', $publicKey);

This works fine in PHP, i am able to encrypt/decrypt using public/private key pair.

The encryptedText is sent to iOS application where i want to decrypt the same string, i tried with multiple approaches and nothing seems to be working, any pointer to do the following is appreciated.

Decrypt OpenSSL encrypted string received from PHP in Objective-C
Encrypt and send data to PHP for Decrypting (should support openssl_private_decrypt)

Seems like [this guide](http://jslim.net/blog/2013/01/05/rsa-encryption-in-ios-and-decrypt-it-using-php/) should be enough to accomplish what you need. — Ja͢ck, Aug 12 '14 at 02:49

I used this library for iOS which worked perfectly.
