<p class="MsoNormal"><span style="color:#1F497D">As a follow up to my previous post, let me emphasize the size expansion is not related to the compression that is applied during encryption. My issue is that I have files that are being transferred to me, and
for a cause that I am trying to track down, gpg begins to decrypt before the file has fully arrived. From my perspective it appears to send gpg into a tailspin. The process seems to be able to continue for a week or more and does not seem to complete.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">From a design perspective, I expect the usual replies of “if that is not what you want to do then don’t do it”. Yes I know. What I am looking to do is to be able to understand why it goes into this race condition
instead of erroring out.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">My ask of the gpg listers, is has anyone ever seen this behavior?<o:p></o:p></span></p>

<p class="MsoNormal">So I completely preface this question is not a valid use case for gpg. I know, I get it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a potential issue that I’m trying to diagnose. I’m trying to understand how gpg will react to the input file size changing during the encrypt or decrypt step.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Right now it appears that the gpg process goes a bit crazy and the 200 MB file I am decrypting becomes 1.2 TB or greater.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is the order of the events<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">

<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>PGP decrypt is invoked on the file. <o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">3.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Since the file is not truly done being sent to me, the file grows in size.<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">4.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>GPG seems to expand the decrypted file many times over.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I suspect is that instead of erroring out, GPG starts the decrypt process over and appends the new output to the previous cycle.. I have not tested this, but will soon.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I just wanted to see if anyone else has seen this happen.<o:p></o:p></p>
