Here it is. A plugin that encodes your texts: This is the readme file:

Text encoder:

This plugin can encode and decode your conversations so you can talk safer.
It is very easy to use, just type /xencode text to encode and that is all.
If a coded text is recieved, you will be asked for a password and then
a window will show the decoded text.

To install this plugin run its installer and clic install.

Commands and tags:
/xencode
    Encodes a text. you'll be asked for a password

/xencoderabout
    blah! Just an about box.

(!xEncoderVer)
    it's replaced by the version of the plugin

This plugin has been developed by me, Carlos Domingo Más (Choli). It is
written in VB, so to run it you will need the VB runtime files. You can
donwload them from the Microsoft site www.microsoft.com
Also, you will need Messenger Plus! It can be donwloaded from its site,
www.msgplus.net

If the installation program does not work, you can do the following:

copy encoder.dll in the Plugins folder of Messenger Plus!
run regsvr32 <Plugins folder of Messenger Plus!>encoder.dll
double clic on install.reg and answer yes
restart messenger

---

And now, you can donwload the installer (if the installer doesn't work, download Encoder.zip and you can see this post too.

Thanks.

- WARNING -
The plugin does NOT work with the last versions of Plus!. If you download it you won't be able to decode your texts. More info: http://shoutbox.menthix.net/showthread.php?tid=14...d=190072#pid190072

So what cryptography do you use?
I came in contact with DJMystic (i got curious what he had done),
and after i told him about this he said he would be putting BlowFish Encryption in SP1.4
Is your encryption weaker, or better than blowfish,
and is it a known encryption or did you make up your own ?

very nice , have you considered making one so all the text it sends is encrypted without having to type /xencod and without having to give the password.

At first I was going to put Rijndael (I don't know if it's well written) It is the best encryption algorith atm, but I thougth it was too much for the pourposes of the plugin and I didn't want to implement it in VB because it whould be so slow. So I've developed one encryption based on the CRC-32 algorith that zip files use. It's weaker than blowfish, so don't expect a high security, it's only to not send your messages in plain text. I also was planing do the plugin in VC++ but there were several reasos that i couldn't do. If one day I do it in VC++ or if I find a good dll (written in C/C++, or course) that encodes Rijndael, I'll change the encryption to it.

That isn't possible with plugins of Plus!. To do that a plugin for Messenger (not Plus) must be developed.

Isn't CRC32 one-way-encryption?

CRC32 is not an encryption system but a hash function (and thus, one-way). What I've done is use the way to compute CRC32 to encrypt the message. I compute CRC32 and at the same time I encrypt the message.

ahh sounds kinda weird to me

Don't worry about the implememtation issues. All you have to know is that I've found a way to encrypt a text by using the code of CRC32

And at this time I have to hear in univ about linked lists in plain C... sigh.  xD

i had an idea for a PGP plugin, perhaps you can help me build it?
