When you've successfully installed gnupg, you should define the GNUPGHOME environment variable and make sure the directory is writeable by the Apache user.
<?php
putenv("GNUPGHOME=/var/www/example.com/.gnupg");
?>
(PECL gnupg >= 0.5)
gnupg_addencryptkey — Add a key for encryption
$identifier
, string $fingerprint
)
identifierThe gnupg identifier, from a call to gnupg_init() or gnupg.
fingerprintThe fingerprint key.
Returns TRUE on success or FALSE on failure.
Example #1 Procedural gnupg_addencryptkey() example
<?php
$res = gnupg_init();
gnupg_addencryptkey($res,"8660281B6051D071D94B5B230549F9DC851566DC");
?>
Example #2 OO gnupg_addencryptkey() example
<?php
$gpg = new gnupg();
$gpg -> addencryptkey("8660281B6051D071D94B5B230549F9DC851566DC");
?>
When you've successfully installed gnupg, you should define the GNUPGHOME environment variable and make sure the directory is writeable by the Apache user.
<?php
putenv("GNUPGHOME=/var/www/example.com/.gnupg");
?>
In this case, $fingerprint is the fingerprint of the public key whose private key shall be able to decrypt the text. The private key that you want to encrypt the text with has to be loaded via gnupg_addsignkey().
