exec and gpg

Hi, I'm using PHP Version 3.0.12 on Free BSD as an Apache module and I'm currently running(or tyring to run) a script that encrypts an email. Im using pgp and exec to do this. The script ran fine for months. Then it suddenly stopped working properly. The error sent back from gpg through the exec command is 127. I can't find any documentation on gpg error codes. Here is the exec command that i'm using with $body being the message $command = "echo \"$body\" | gpg -a -e -u 'blah@blah.com -r 'blah2@blah.com' "; exec($command,$encrypted_text,$errorcode); Like I said this worked fine for months but now its just not encrypting. I've taken this echo and | and run it command line and it works fine when substituting text for $body. Thats what is strange. I know(or think) the command is right but the text will just no longer encrypt. Please HELP!!! Thanks, Andrew Presley apresley@insolwwb.net
