openssl_open
Description
openssl_open() opens (decrypts) sealed_data using the private key associated with the key identifier priv_key_id and the envelope key env_key, and fills open_data with the decrypted data. The envelope key is generated when the data are sealed and can only be used by one specific private key. See openssl_seal() for more information.
=ד 1. openssl_open() example
// $sealed and $env_key are assumed to contain the sealed data // and our envelope key, both given to us by the sealer. // fetch private key from file and ready it $fp = fopen("/src/openssl-0.9.6/demos/sign/key.pem", "r"); $priv_key = fread($fp, 8192); fclose($fp); $pkeyid = openssl_get_privatekey($priv_key); // decrypt the data and store it in $open if (openssl_open($sealed, $open, $env_key, $pkeyid)) echo "here is the opened data: ", $open; else echo "failed to open data"; // free the private key from memory openssl_free_key($pkeyid);
