openssl_open
(PHP 4 >= 4.0.4, PHP 5) openssl_open -- Open sealed data
Descriptionbool openssl_open ( string sealed_data, string &open_data, string env_key, mixed priv_key_id ) Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки. If successful the opened
data is returned in open_data.
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.
Пример 1. openssl_open() example
<?php
// $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
);
?>
