i'm about to use gnupg to encrypt and decrypt files. The strange thing is, encrypt works fine, but decrypt always returns false.

Here a simple php script encrypting and decrypting content:

$content = 'test text';
putenv("GNUPGHOME=/PATH_TO_GPG_PATH");
$gpg = new gnupg();
$gpg->addencryptkey("FINGERPRINT");
$enc = $gpg->encrypt($content);

var_dump($enc);

$gpgD = new gnupg();
$gpgD->adddecryptkey("FINGERPRINT","PASSPHRASE");
$plain = $gpgD->decrypt($enc);
var_dump($plain);

Versions

Debian packages

gpgv 1.4.18-7

libgpgme11:amd64 1.5.1-6

pecl

Package Version State gnupg 1.4.0 stable

PHP version: PHP 7.1.11-1+0~20171027135825.10+jessie~1.gbp2e638d

Anyone experienced this problem already? I'm out of ideas. Thank you in advance.

For me the issue was the PHP application didn't have the right permissions to the key files. If you generate the keys with the 'gpg' cli (like I did) it makes the files owned by 'root'. So I just needed to change them to be owned by the php application user.

The folders I needed to update permissions on were {GNUPGHOME}/openpgp-revocs.d and {GNUPGHOME}/private-keys-v1.d

My guess for you its the /private-keys-v1.d folder since you can't decrypt it.
