Encrypt using private key, decrypt using public key.





Use this for posting signed messages:  Anyone with access to


your public key can read it, but they can't create one with


your signature.





<?php


echo "Source: $source";


$fp=fopen("/path/to/private.key","r");


$priv_key=fread($fp,8192);


fclose($fp);


// $passphrase is required if your key is encoded (suggested)


$res = openssl_get_privatekey($priv_key,$passphrase);


/*


 * NOTE:  Here you use the returned resource value


 */


openssl_private_encrypt($source,$crypttext,$res);


echo "String crypted: $crypttext";





$fp=fopen ("/path/to/certificate.crt","r");


$pub_key=fread($fp,8192);


fclose($fp);


openssl_get_publickey($pub_key);


/*


 * NOTE:  Here you use the $pub_key value (converted, I guess)


 */


openssl_public_decrypt($crypttext,$newsource,$pub_key);


echo "String decrypt : $newsource";


?>
