this is a script I made to talk with other people and avoid from being heard by others, get the other person this script, and you can talk freely.

Simply type CRYPT.

Very interesting. Seems to be somewhat based on the codetalk script I've got on here somewhere, which is in turn based off someone else...

I've got a Morse Chatter too, that is DIRECTLY based on someone elses.

But regardless of whether you based this on someone's work or created it uniquely, nice work :)

here is a rotate 13 example based on a morse chatter(I learned a lot from it).
i've enchanced the script and fixed some stuff.

One thing I would suggest is taking a look at my morse chatter (if I posted it here, I'm no longer sure if it was here or another forum...) and looking at how I implemented it to be all command line and multi-channel.

For instance, doing:
morse chat Hi this is morse code

would send the morse to the chat channel as:
{Chat} Ralgith: Morse Code: (message in morse here)

I do this, so that anyone with the trigger will automatically get the decoded message, because I trigger off the "Morse Code:" and then use #ECHO to echo the decoded message back to them automatically.

I also do this on my code talk, which I never released to the public... but its the same thing as your ROT-13 at the most basic level. You just need a Unique prepend to it.

If you implement this into your code talkers, it will eliminate all the extra steps, and speed it all up a lot.

You can also make it catch special extra argument channels such as tell using something like this (I use %ismember() so that you can simply make it a list):

Couldn't you use %subchar to implement Rot13 very easily? I've never studied anything to do with cryptography, not even the basics, so forgive me if I'm wrong. But it seems a very simple operation.

Yes Fang you could :)
You just take your string and loop through each individual character replacing them with their Rot-13 equivalent. This is how I did my coded chat system. Thanks for mentioning it since I forgot ;)

Why bother looping? I meant something like

%subchar("abcdefghijklmnopqrstuvwxyz","mnopqrstuvwxyzabcdefghijkl")

I loop through each character because I have some special character checking. But yes, I get what you're saying, though you would need to do it as:

%subchar("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz","MNOPQRSTUVWXYZABCDEFGHIJKLmnopqrstuvwxyzabcdefghijkl")

in order to cover capped letters too, wouldn't you?

ahhh, but I didn't know of subchar at the time of making this.
would be something like this, right?
#ALIAS encrypt {#var endparam %subchar(%-1,"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz",NOPQRSTUVWXYZABCDEFGHIJKLMnopqrstuvwxyzabcdefghijklm")
#echo @endparam
#noop
}

ok, here's the end result.

Yup, looking nice. Though in a teasing way I'm still of the opinion that you should implement it as automated instead of the chunky manual system you're using :)

Something like this:

you had a little bug on the decryption trigger.

so people, use his code:

Oops, nice catch lol! Stupid missing %1 :D
