Hi,

I'm currently evaluating GPG as a product and I'm having some problems 
invoking gpg commands from within a PHP script.

Currently I'm am able to encrypt files from the command line no problem 
running under redhat linux (latest version) on an Apache web server but as 
soon as I try the same command line via the system() command in PHP - the 
file is no longer encrypted. A return code = 2 is returned by the system 
command. However when I test the very same PHP script locally on my PC which 
is running under Windows 2000 - gpg is invoked and the file is encrypted 
beautifully.

So I then tried creating a perl script which calls gpg to encrypt a file. 
This works fine under linux on the Apache web server when you call the perl 
script from the command line. However when I then use a PHP script to call 
the perl script to do the encryption - the perl script is invoked and runs 
but once again the encryption does not take place !!! I know the perl script 
is run because there are print commands displayed as part of the output !!!

I am at a loss as to what to try next. Is it a permissions thing between PHP, 
linux & GPG ?

Any help would be very much appreciated as I'm getting nowhere fast.

Thanks
Christine
