App not working

[Spitfireap]

Hey !
This app seems really great, unfortunately I can't find a way to make it works on NC21. I've installed gnupg and
php -i | grep -i gnupg do returns :
/usr/local/etc/php/ext-20-gnupg.ini, gnupg gnupg support => enabled
Unfortunately upon clicking on "Download server Key" I get redirected to mycloud.com/index.php/apps/gpgmailer/key/download/server but I get a file not found warning
.
And on the server there is no key folder under apps/gpgmailer/
GpgMailer do send a warning in the log
[gpgmailer] Error: Creating server GPG key pair failed. Emails are not going to be signed, expect keys are server keys imported manually POST /index.php/settings/apps/enable from XX.XX.XX.XX by adrien at 2021-05-16T12:11:55+00:00
I also get two log entries : `[PHP] Error: Error: sizeof(): Parameter must be an array or an object that implements Countable at /usr/local/www/nextcloud/apps/gpgmailer/lib/Service/Gpg.php#231 at <>

Also regarding importing my own public key, I try to copy it from thunderbird and pasting, but I get an "Error importing public key"...

`

[Spitfireap]

Okay here is why I don't have any key generated :
`[gpgmailer] Warning: gpg --batch --gen-key foo:
Array
(
[0] => gpg: Warning: using insecure memory!
[1] => gpg: foo:4: missing argument
)

This took 0seconds.`

Seems to be due to Name-Comment.
By deleting it I get a new error (yess) key generation failed: Unknown elliptic curve. After looking at here https://askubuntu.com/questions/861978/unattended-gnupg-key-generation-for-ecc/861985 I've just added Key-Curve: nistp256 and Subkey-Curve: nistp256 in foo.
And then key generation seems to work :
`[gpgmailer] Warning: gpg --batch --gen-key foo:
Array
(
[0] => gpg: Warning: using insecure memory!
[1] => gpg: key 91AB6DB08A49BFDF marked as ultimately trusted
[2] => gpg: revocation certificate stored as '/mnt/data/.gnupg/openpgp-revocs.d/C7FFDEA2B732DD6E4E6C1B0891AB6DB08A49BFDF.rev'
)

This took 0seconds.

POST /index.php/settings/apps/enable`

but again :

and [gpgmailer] Warning: No server GPG key found so no signed emails are possible.

It seems that every foreach and sizeof raises an error...

[tacruc]

Something is going wrong while gpg->keyinfo eg. in

gpgmailer/lib/Service/Gpg.php

Line 230 in 7c3cbae

$keys = $gpg->keyinfo($email);

You could use echo $gpg -> geterror(); afterwards to get the error message of php_gnupg.
The foreach fails because keyinfo returns for some reason false.

[Spitfireap]

Okay, well only thing the geterror() returns is [gpgmailer] Warning: could not init keylist`

And here is a more in-depth view of the debug of keyinfo(). I tried to activate the debug on nextcloud but I get so many RuntimeException that log for the PHP app is not saved... Tell me if you need these 9 more entries and I'll try to see if I can get them.

[tacruc]

Could you try to get this small example running?
It seems to be some problem with gnupg.

<?php

// make sure that this folder is NOT accesible as an URL

error_reporting(E_ALL);
$res = gnupg_init();
gnupg_seterrormode($res,GNUPG_ERROR_WARNING);

$info = gnupg_keyinfo($res, '');
echo geterror($res); 

[Spitfireap]

Sadly I only get
AH01071: Got error 'PHP message: PHP Warning: gnupg_keyinfo(): could not init keylist in /usr/local/www/apache24/data/test.php on line 9'
no matter if I set the GNUPGHOME or not :(. It's on a fresh new jail on freebsd but it does the exact same on my nextcloud jail.

And no error output from the gnupg_geterror($res);

[tacruc]

Could you check the permissions of the .gnupg folder?

http://superuser.com/questions/954509/ddg#954536

[Spitfireap]

On data/.gnupg and data/user/.gnupg I've got
drwx------ 2 www www 5 May 17 17:04 .gnupg so 700 by default. Changing them to 777 doesn't change anything.

[tacruc]

and apache/php is running as www, www-data, wwwrun or php-fpm?

http://php.adamharvey.name/manual/en/function.gnupg-init.php#121851

[Spitfireap]

apache and php-fm run both under www user.

[Spitfireap]

It's driving me crazy. I tried all day yesterday and still can't at least introduce a new bug :p. I even changed php version to 8.0 but didn't improve anything. Do you think I should open an issue at https://github.com/php-gnupg/php-gnupg ?
Thanks for your help !

[tacruc]

If the basic example of php-gnupg is not working. They might know whats going wrong. I'm sorry but I have no idea left right now.
