Description:
------------
In my example, here are the keys generated by Cryot_RSA :
publicKey :
* exp = 65537
* mod = 269591262673059623598041158204757458369
privateKey :
* exp = 133065873704138619452937677773081243649
* mod = 269591262673059623598041158204757458369
If I encrypt the following messages : "abc" and "OK", I get respectively : "101359587981532728696079137059242763524" and "210161276781397745678118236955275625333".
After, if I decrypt the encrypt messages, I can't find the expected result but an empty string.
WHY ????
Thanks.

"Bug #15900 Abnormal result after the decryption" fix!!!!
This code is located in the file KeyPair.php beginning with the line number 591 caused an error in Windows XP.
/*********************************************************************************************************
*
* // try to create public key object
* $obj = new Crypt_RSA_Key($n, $e, 'public', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj->isError()) {
* // error during creating public object
* $this->pushError($obj->getLastError());
* return false;
* }
* $this->_public_key = &$obj;
*
* // try to create private key object
* $obj = new Crypt_RSA_Key($n, $d, 'private', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj->isError()) {
* // error during creating private key object
* $this->pushError($obj->getLastError());
* return false;

* $this->_private_key = &$obj;
*
*********************************************************************************************************/
Revised below.
/*********************************************************************************************************
*
* // try to create public key object
* $obj1 = new Crypt_RSA_Key($n, $e, 'public', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj1->isError()) {
* // error during creating public object
* $this->pushError($obj1->getLastError());
* return false;
* }
* $this->_public_key = &$obj1;
*
* // try to create private key object
* $obj2 = new Crypt_RSA_Key($n, $d, 'private', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj2->isError()) {
* // error during creating private key object
* $this->pushError($obj2->getLastError());
* return false;
* }
* $this->_private_key = &$obj2;
*
*********************************************************************************************************/
Or like this
/*********************************************************************************************************
*
* // try to create public key object
* $obj = new Crypt_RSA_Key($n, $e, 'public', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj->isError()) {
* // error during creating public object
* $this->pushError($obj->getLastError());
* return false;
* }
* $this->_public_key = $obj;
*
* // try to create private key object
* $obj = new Crypt_RSA_Key($n, $d, 'private', $this->_math_obj->getWrapperName(), $this->_error_handler);
* if ($obj->isError()) {
* // error during creating private key object
* $this->pushError($obj->getLastError());
* return false;
* }
* $this->_private_key = $obj;
