Decrypting a log file which is 2.75MB takes an agonising 26 seconds. It's the 8th -- and I dare think what the log file size will be by the end of the month, and how long the LogViewer will take to show me the log!

Is there anyway chance of improving the speed Patchou?

well, it shouldn't take that long... it depends on your system specs really. All I can suggest is to decrease the encryption key size (preferences), that's what will make the most difference (for future generated log files).

Thanks for your reply Patchou.

My system spec isn't too flashy... AMD AthlonXP @ 2.21GHz.

Encryption key size is 640.

Does the Log Viewer decrypt and write to the HTML file as its going along? Or does it decrypt, then generate a HTML file?

Basically, encrypted log files are HTML files which were encrypted by Plus! Live. When Plus! opens the log file, it checks the given password by decrypting a known signature in the log file and if that result matches the original signature, it decrypts the whole log file and stores it in a temporary location. Then, it loads that file in the Log Viewer window. In fact, you can encrypt any type of file with the Plus! encryption, and it'll work perfectly fine.

In my opinion, 2.75 MB for a log file is quite huge, assuming that they're just HTML files. HTML is just text, the images (smilies, wink thumbnails and the like) are stored in a subdirectory in the logs folder. So, I think that 2.75 MB of logged chat messages is quite big for a period of 8 days, and I doubt you have lots of other huge log files. Maybe you're just chatting too much?

Thanks for your reply Mattike.

Yes maybe I should tell her to
stop

And spamming me with nudges

But on a serious note.

Is there any chance of future versions of Messenger Plus! to incorporate 7zip to --

Output: Generate HTML File --> 7zip (via command line, compress and output to file) --> Encrypt log --> Output to .ple
Input: Decrypt log --> 7zip decompress and output to HTML file --> Show log in viewer

Compressing a 2.75MB HTML file with 7zip outputs, approximately, a 114KB file.

Imagine the speed difference in encrypting and decrypting a 114KB file over a 2.75MB file!

Ziping before encrypting could be a good idea, the problem however is that logs, by nature, are ever growing files. Compressing each block in the file could be prone to error and cause many differnt kinds of problems. Still, I'll keep that in mind.

Yes, Patchou -- This is the problem with zipping. However, even now, without much change, filesizes could be reduced by over half in most cases...

code:

---

  <tr><th><span class="time">(16:06)</span> Gary: </th><td style="font-family:&quot;Georgia&quot;;color:#000080;font-weight:bold;">almost got parking ticket</td></tr>
166 bytes

---

code:

---

<tr><th><i>(16:06)</i> Gary: </th><td class="a">almost got parking ticket</td></tr>
83 bytes -- 50% Reduction

you just can't add this kind of thing in html logs... remember that log files grow, the header, once written in the file, cannot be changed.

By the way, I found an annoying thing which may grow html files rapidly.

When people use Plus! formatting tags, if they write like [b]hel[/b][b]lo[/b], then in log file it looks like

code:

---

<span font-weight:bold>hel</span><<span font-weight:bold>lo</span>

---

code:

---

<span font-weight:bold; color=fffff>   H   </span>
<span font-weight:bold; color=ffff00>   e   </span>
...
..
.
<span font-weight:bold; color=fcfc32>   t   </span>
