RSA

I have mobile application that encrypts strings with RSA and sends that encrypted data to PHP web server.

After a search I found that phpseclib is used to decrypt RSA
Latest version 2.0.

No matter what I do I receive despite error despite used mode

Am i doing something wrong?

What I have tried:

Private key for decryption:

-----BEGIN RSA PRIVATE KEY-----

Encrypted message (base64 encoded):

PHP sample code:

$rsa = new RSA();
$rsa->setEncryptionMode(RSA::ENCRYPTION_PKCS1);
$rsa->loadKey($privateKey); 
echo $rsa->decrypt($strBase64);

Result:

Notice: Decryption error in C:\xampp\htdocs\prim41ws\vendor\phpseclib\phpseclib\phpseclib\Crypt\RSA.php on line 2553

Mode:

$rsa->setEncryptionMode(RSA::ENCRYPTION_OAEP);

Result:

Notice: Decryption error in C:\xampp\htdocs\prim41ws\vendor\phpseclib\phpseclib\phpseclib\Crypt\RSA.php on line 2432

Mode:

$rsa->setEncryptionMode(RSA::ENCRYPTION_NONE);

Result:
