How to decrypt yEnc?

I use "yproxy". It will cost $17 and it is well worth it. I used to hate
it when someone posted in yenc.

yEmc seems to be some sort of crypto - how do U see it?

This is sure to be unpopular, but I've seeing "no Yenc" comments -
rules, sometimes - on newsgroups for at least 10 years or so. That was
chiefly because people didn't want to pay up for it (or even, to pay
at all).

But the Yenc compression has very real advantages in terms of enhanced
resolution but with reduced file size; for newsgroup users who
download binaries, in fact, it's a real service.

10 years on and the world has gone from Windows Diddly Squat to Vista.
I think we should embrace the future. In my case, I paid something
minimal for a proper version of Agent (www.forteinc.com) and have
never given it a second thought in all the years since.

It's even more encouraging to see that there are free Yenc decoders
available now.

There are free encoders. I bought yproxy because it had some features i
liked. You are right about the enhanced resolution. Large files opened
easily. I would like to add that I am not an advocate for yenc. Have a
great day!

Here's a jpg of size 263Kb - no yEnc.

And the same one Yenc'd to see how different it is.

Rusty that was a good illustration of yEnc! (Nice photo too.)

I get so very tired of people whining about those who use yEnc.

This file was NOT encoded with the new yEnc.... Result 64Kb

JPG is a 'lossy' image compression scheme. yEnc is a lossless file
transmission protocol. They are not the same. Tranmission of binary
files on Usenet requires encoding as the Usenet protocol - NNTP - does not
allow for the straight transmission of 8 bit data, instead requiring it be
recoded to a 7 bit ASCII format using a method called 'MIME'. This
expands the size of the ~transmitted~ file by a rather hefty amount. Once
it is decoded on the receiving computer it is once again the original file
as sent by the poster.

yEnc is a different, more efficient form of transmission encoding that,
like MIME, has no effect on the data in the original file. What it does
is use bandwidth more effectively by using fewer bytes. This may not be
so noticeable with small files like image JPGs, but it certainly helps
with larger files such as video and disc images, legal or otherwise.

Rusty's example showed how much transmission bandwidth can be saved for
the same ~identical~ JPG image using MIME vs yEnc.

Willem's example showed how easily you can corrupt a beautiful image with
JPG artifacts by over-compressing it.

I use the free XNews newsreader to follow this group. It handles yEnc
transparently with no problems. I have used yProxy in the past with
similar trouble free results. The main complaint I hear about yEnc is the
MS Outlook Express does not support it 'out of the box', and a lot of
folks still use OE for newsreading.

A sizeable percentage of this group have requested that others please use
MIME rather than yEnc when posting, most of the regulars have agreed to do
this out of courtesy. I find it a little annoying when a new poster gets
flamed immediately for posting in yEnc rather than being asked politely if
they will use MIME - it is just a bit rude to blow someone arse over
teacups out the door when they arrive with new images to share,
dontchathink?

My two cents, and I expect change!
