GPG is always returning 2 at the result. My code is as follows
$cmd = "/usr/bin/gpg -a --recipient $to -e -o $outfile $infile";
Where outfile is the file where the encrypted data will be written and infile is the unencrypted data.
I don’t know why this is happening. Can anyone please tell me what’s wrong. Thanks.
Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
GPG is asking whether you want to continue on with the encryption using an unsigned key. Since no user can input
Y it produces an error.
To fix this put the following switches
See this message: http://lists.gnupg.org/pipermail/gnupg-users/2008-January/032410.html
It appears to be a permission problem. gpg is trying to access a directory that it can’t have access to, so it fails with a fatal error. (error code 2)
You can fix that by specifying a homedir directive with a directory writable by gpg. Like this:
$cmd = "/usr/bin/gpg -a --recipient $to -e -o $outfile $infile --homedir /path/to/dir";
Set the name of the home directory to directory
If this option is not used it defaults to
“~/.gnupg”. It does not make sense to
use this in a options file. This also
overrides the environment variable
You also might want to concider adding key to trusted keys list:
gpg.exe --edit-key KEY_NAME trust 5 (level of trust) Y Save
I’ve had some problems of
--always-trust parameter not functioning properly on XP windows, this helped me solve the problem.
I had the same problem, but for the decoding command
At first and general, you can get the error message by redirecting stderr to stdout.
$cmd = "/usr/bin/gpg -a --recipient $to -e -o $outfile $infile 2>&1";
Then you can modify gpg’s parameters to suit your needs. Because I had a files encrypted with a key with pass phrase I had to add several parameters.
I started with
gpg -o $out -d $path
But it complained, that it can not open tty, then with –no-tty it outputs some other errors and finally the command for decoding files with key with pass phrase is
gpg --batch --passphrase $pass_phrase --no-tty -o $outfile -d $path_to_encoded_file
I hope this helps someone.
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
