Encrypted Email with GnuPG

[m_e_e]

Hi All,

What I have done?

• I have installed GnuPg in Windows XP machine.

• The environment variable PATH= C:\Program files\Gnu\GnuPG;

• I have generated public and private key.

• Key ring is C:\ Documents and Settings\user name\Application Data\gnupg\pubring.gpg

• I kept text file in C:\wamp\www\plain_text.txt

• I run the DOS command like this: C:\wamp\www> gpg –r kkkk –o entrypted_text.txt –e plain_text.txt

• It creates encrypted_text.txt in C:\wamp\www directory.

Problem?
I want to perform this task using php program. I tried following coding and it displays “2”. But it does not creates encrypted_text.txt.
<?php
$command=” gpg –r kkkk –o encrypted_text.txt –e plain_text.txt”;
system($command,$result);
echo $result;
?>

Note: if I use following command, it displays GnuPG version
$command = “gpg --version”;
Any suggestion to get encrypted_text.txt file on www directory????

Try using [man]shell_exec/man instead and echo the value it returns - see if you can get a full error message.

Hi bradgrafelman,

I tried with following functions:

• passthru() out put was "2"

• exec() output was "Array()"

• shell_exec() was blank.

Following was my coding:

<?php
$command=” gpg –r kkkk –o encrypted_text.txt –e plain_text.txt”;
echo shell_exec($command);
?>

bradgrafelman,

I did not get any error message. But I did not display "2". The screen was blank.

Thanks

It did not display any error

Does the code in your script really have curly quotes and a space before 'gpg'' in $command?

I tried with following properties:

• $command = "gpg -r kkkk -o encrypted_text.txt -e plain_text.txt";

• $command = 'gpg -r kkkk -o encrypted_text.txt -e plain_text.txt';

• $command = " gpg -r kkkk -o encrypted_text.txt -e plain_text.txt"; // space before gpg

• $command = ' gpg -r kkkk -o encrypted_text.txt -e plain_text.txt'; // space before gpg

But no luck.

Sorry.. I have no idea what the problem is.

You might try using [man]proc_open/man as suggested over here to try and get an error message from GnuPg and debug it... but beyond that, I'm out of suggestions.

Thanks Bradgrafelman, thanks for your try.
