Gnu PGP and PHP

Posts: 271 · Posted: Wed Jul 27, 2005 12:43 pm

I'm trying to modify a script I found to work but my PHP knowledge gets fuzzier everyday since I don't use it as much any more, could anyone give some tips on why I'm getting a 'No input file specified error'? Or perhaps suggest another approach? The goal is to take text from a form, encrypt it with a specific pgp key and email it.

Code:

<?
$message = "this is the text to encrypt with gpg";
$sendto = 'Dummy Key <another@fake.email>';

system("mkfifo pipein");
system("mkfifo pipeout");
system("gpg --encrypt -a -r '$sendto' > pipeout < pipein &");
$fo = fopen("pipeout", "r");
$fi = fopen("pipein", "w");
fwrite($fi, $message, strlen($message));
fclose($fi);
while (!feof($fo)) {
$buf .= fread($fo, 1024);
}
echo $buf;
unlink("pipein");
unlink("pipeout");
?>

I'm also not sure if the OS supports bi-directional pipes. (I'm running this code on a SmarterLinux account).

Thanks.

I know this is a really old post, but I thought I'd take a look anyway. I'm kind of confused with this. I don't know much of anything about encryption, so maybe that's part of it, but you seem to be opening gpg before you actually place any content in your files? That seems really weird

I'd recommend checking a tutorial like this:

or maybe using a 3rd-party function like this:
