gnupg_import()

(PECL gnupg >= 0.3)

Imports a key

说明

gnupg_import(resource $identifier,string $keydata): array

Imports the key$keydataand returns an array with information about the importprocess.

参数

$identifier

gnupg 标识符，由对gnupg_init()或gnupg的调用生成。

$keydata

The data key that is being imported.

返回值

On success, this function returns and info-array about the importprocess. On failure, this function returns FALSE.

范例

Example #1 Procedural gnupg_import() example

<?php
$res = gnupg_init();
$info = gnupg_import($res,$keydata);
print_r($info);
?>

Example #2 OO gnupg_import() example

<?php
$gpg = new gnupg();
$info = $gpg -> import($keydata);
print_r($info);
?>

The return array consists of the following values:
(
 [imported] => (int),
 [unchanged] => (int),
 [newuserids] => (int),
 [newsubkeys] => (int),
 [secretimported] => (int),
 [secretunchanged] => (int),
 [newsignatures] => (int),
 [skippedkeys] => (int),
 [fingerprint] => (string)
)
When invalid content is passed, all values, even skippedkeys, is 0. The fingerprint value does not exist then.

I recommend that the key may be generated in shell command line, then you export the keys using this group of commands.
gpg --export -a "User Name" > public.key
gpg --export-secret-key -a "User Name" > private.key
to use it, at the import and use it for encryption and decryption.
<?php
$GnuPG = new gnupg();
$PublicData = file_get_contents('public.key');
$PrivateData = file_get_contents('public.key');
$PublicKey = $GnuPG->import($PublicData);
$PrivateKey = $GnuPG->import($PrivateData);
echo 'Public Key : ',$PublicKey['fingerprint'],' & Private Key : ',$PrivateKey['fingerprint'];
?>
