@jackmiauthorFeb 26.2009 — #thank you. unless you see it you can't help me so here it is. windows does it a little different. I checked the gpg command line and it works fine. it creates the temp file in windows/temp folder. but when executed the script throws an error about $contents as not recognized. it seems to me it's in the gpg command line but I just don't know how to trouble shoot. I went through quite a few examples and before I give up I figured I'll give it a shot here.

thanks again for reading.

@scragarFeb 26.2009 — #You should be careful using 's and doubt quotes when you don't want the special effects can offer.

I would also echo out the results of your command, just incase that's where your error occurs.

@jackmiauthorFeb 28.2009 — #I have now spent quite a few nights on this.

I enabled php.ini to show all errors and there was nothing. I tried not writing to a file and it basically does the same thing. Looks like the gpg command doesn't get exectued. the script used to complain: unable to fork - but I fixed it by giving permissions to iusr and iis. I've added correct paths and put gpg.exe in all appropriate folders. php code is fine I think. What am I missing? Is there a way to show or log all output either from php and/or cmd?

thank you for your time.
