Need Quick SIMPLE encryption/URL converter

Hello,

Thank you MUCH for responding!

I replaced the code with yours and I tried going to several websites, and this is the error that it spits out:

"CGIProxy Error
Couldn't find address for www.676s6s676p652r636s6q.com:"

This identical error pops up with ANY address one types in the box, so something must be going funky with the encryption and/or decryption.

Please feel free to actually visit the running script with your suggested changes @

If there's anything I can do to assist with the prob, please don't hesitate to holler - with your help, I hope we'll find a way to get this workin'

Thanks again

OK, reduce it please to this:


function _proxy_jslib_proxy_encode(URL) {
  URL= URL.replace(/^([\w\+\.\-]+)\:\/\//, '$1/') ;
  URL= URL.replace(/(.)/g, function (s,p1) { return p1.charCodeAt(0).toString(16) } ) ;
  return URL ;
}

function _proxy_jslib_proxy_decode(enc_URL) {
  enc_URL= enc_URL.replace(/([\da-f]{2})/gi, function (s,p1) { return String.fromCharCode(eval('0x'+p1)) } ) ;
  enc_URL= enc_URL.replace(/^([\w\+\.\-]+)\//, '$1://') ;
  return enc_URL ;
}

Hello again,

I copied and pasted your code and this is the error I'm getting now:

"CGIProxy Error
Couldn't find address for www.676f6f676c652e636f6d.com: "

So, there has been some change in the error with the new code but something still looks a skew.

Good luck, thanks for your help - appreciate it ;)

Wait a moment, the browser script allone has to code and decode the url before sent to CGI and when received back from CGI, but the CGI itself needs also to know what decoding to do on encoded URLs to be able to fetch them. Do you see what CGI is doing the URL decoding before proxying on server side?

Howdy again,

Sorry for the trouble - I think I may have found something related in the script.

This is what the original author commented in the script before the code below that I found (which appears to be what the CGI script is doing):

[quote]
IMPORTANT: If you modify these routines, and if $PROXIFY_SCRIPTS is set
#   below (on by default), then you MUST modify $ENCODE_DECODE_BLOCK_IN_JS
#   below!!  (You'll need to write corresponding routines in JavaScript to do
#   the same as these routines in Perl, used when proxifying JavaScript.)
[/quote]

The following was on lines 385-401 in the original script:
*************************
sub proxy_encode {
    my($URL)= @_ ;
    $URL=~ s#^([\w+.-]+)://#$1/# ;                 # http://xxx -> http/xxx
#    $URL=~ s/(.)/ sprintf('%02x',ord($1)) /ge ;   # each char -> 2-hex
#    $URL=~ tr/a-zA-Z/n-za-mN-ZA-M/ ;              # rot-13

    return $URL ;
}

sub proxy_decode {
    my($enc_URL)= @_ ;

#    $enc_URL=~ tr/a-zA-Z/n-za-mN-ZA-M/ ;        # rot-13
#    $enc_URL=~ s/([\da-fA-F]{2})/ sprintf("%c",hex($1)) /ge ;
    $enc_URL=~ s#^([\w+.-]+)/#$1://# ;           # http/xxx -> http://xxx
    return $enc_URL ;
}
*************************

I hope that helps - I'm not sure if its the right thing because I've modified the code above to encrypt the actual URL in the Address Bar of the browser, and its worked fine without any of the url input encryption.  However, now that I think about it - the url in the address bar is the same as the request, and if it can't decrypt the request, we're SOL anyways...

Anywho, thanks for spottin' that and I apologize for not seeing it before - hope that helps!

Thank you again!

Zvonko - Thank YOU!

I tried your suggestions, and everything is now well!  Without your help, I fear that this would have never been solved - so thank you much!  I've awarded you your well deserved points ;)

I may want to modify this script slightly for some minor redirection, but will make another question and would be thrilled if I had your assistance!  Thanks again and keep up the great work!
