I use a new algo with a XoR but like in that :
In the debug.print I can see the text who is over that line but in the text box I only see that :Code:p=blpHb fLg?mEw{fRrw$)f+bIv)"8f+j1"f)#opkSn=m6#/lqrwpyQ ZnSx>mgTHKHZTrL7f'vpS&pZ`'=>w|"% ",D: p,a+q2"KrRA! nfHu9jUãgodb q#—#q›wCfa4#T b5a f-#5mq|oDj p?b7v|[
Why ?Code:p=blpHb
And how can I fix that ?
Set your text to MultiLine.
Already done that... I think it's because charactere erase some other ? Or maybe not ? I can not figure what's wrong with the Textbox.
I cannot test it... cos I don't have the string to do it.
Anyone already had that problem with XoR operation ?
Have you tried setting that to the text property of a RTB?
I didnt but what it's weird is when I paste the code in the textbox it's ok but the code is not decrypted at all because I think that erase chr. :(
Why do you paste it? I don't get what you're trying to do.
I XoR a sentence and in the debug print i see the crypted text but in the textbox i do not see all the text but if i take the text in the debug and I paste it in the text box and xor it the code is decrypted at half so I think than it have a chr who erase something.
The only way I can help you is if you post the code (or send it by email [email protected] -I'm at work- ) and tell me the sentence you're trying to encrypt.
ok i have do something when the chr is under 32 than do something but it do not work perfectly so if some one have a solution please write it there. :)
You'll need to change your encryption so that you could never get a chr below 32.
Well said, nishantp.
A richtextbox will display chr$(0) just fine.
The problem with it isn't actually a windows problem as nishantp stated. VB was built on C++, thus it inherits flaws. As you may know chr$(0) is null, C++ intreprets this as end of string. That's why anything after is is ignored. Possible solutions, as I stated one before richtext, another is converting to hex.
When you convert though make sure you either use format or string(2-len(hex),"0") & hex, otherwise you'd get a truncated string which would be extremely hard to decrypt, especially for a program. To do it you'd have to do redundency checking, to see if it's really just one character or two... which would mean your characters would have to have the values stored in them.
Say I have hi,
asc(h)=104
lastchar = 0
104 xor lastchar xor 1 = 105
lastchar = 105
asc(i) = 105
asc(i) xor lastchar xor 2 = 2
or..
you could split up values
< 128 = 1
> 128 = 0
then mark the length for each hex values...
as you can see this gets long and complicated...
Richtext is the way to go!
I've proposed that before...Quote:

But, he didn't care to try it. :rolleyes:Quote:

Great minds think alike Mc Brain.
;)
Yeah... I couldn't agree more -in the great mind stuff :D ;) -Quote:

Perhaps better stated.. great Brains.
:p
Ok, I could have agreed more.... I agree more now! :D
BTW, did that solve your problem, DaoK? If not... just change the encrypting algorithm.
are you going to post a test program, compiled, so that i can try some things out?Quote:

here is a test to try to crack my XoR encryption.
The message will be like that : HelLO yOu i Am YOUr fRIendCode:$#7iIz+v'#>b5w7vHl(
This is just an example because I do not know why it do that but it freak out all chr...Try to crack the txt in the code quote and tell me if you crack it how you did.
ok I will try RTB but I wanted to use a Textbox to have the least possbile OCX in my project.
Maybe yes and maybe no, I need to work a little on it than maybe. The algo is better of my last one :) I am proud of it :)Quote:

so post the program!
in compiled form, so we have something to work with!
Wait! With a richtextbox it doesnt work, lets me work on it and I will come back to give you some news.
I have solve my problem, I want to thx all who helped me.
If someone is interested the problem was for an unknown reason a move of 32 chr each letter that why all capital letter changed and some time double line didnt work. Anyway, thx you all
post a program for us to test the encryption!
