hello all

i was playing with blowfish and vdsipp i have a question if a person has a txt file that is encryted how can you make vdsipp decryted then show it in a list? meaning this:

Code:

internet http,get,1,%%whateversurl
%%dec100 = @Blowfish(DecryptFile,test,c:\whatever\download2.txt,c:\whatever\download.txt)
   LIST CREATE,1
  if @GREATER(@INTERNET(HTTP,CONTENT-LENGTH,1),0)
   rem LIST ADD,1,@INTERNET(HTTP,CONTENT,1)
   list clear,L1
   LIST ADD,1,c:\whatever\download.txt



Code:

:HTTP1ONGETDONE
  LIST CREATE,4
  rem LIST ADD,4,@INTERNET(HTTP,CONTENT,1)
  LIST ADD,4,%%dec100
 dialog select, 0
  LIST CLEAR,L1
 LIST ASSIGN,L1,4
    LIST CLOSE,4
  %%Downloading = No


this above code does NOT work right...i can however make it work BUT then the txt file is encryted Sad how can i make it decryted?

p.s i have tried many diff ways to have it decryted it then show it in a list but no luck yet Sad


thanks

Hey Tim,

You need to use the INTERNET HTTP,DOWNLOAD command instead of the INTERNET HTTP,GET command. That will save the file to disk, then you can decrypt it. You can't decrypt a file from the harddrive if you have only retrieved it to the memory buffer.

Try this:

Code:
internet http,download,1,%%whateversurl,c:\whatever\download.txt
%%dec100 = @Blowfish(DecryptFile,test,c:\whatever\download.txt,c:\whatever\download2.txt)
   LIST CREATE,1
rem -- I think download2.txt is decrypted now --
   LIST LOADFILE,1,c:\whatever\download2.txt

Good example FF... Make the process as simple as possible, Tim.

Download the encrypted file to the harddrive
Decrypt the file
Load the file into your list

Also, his code assumes you haven't used LIST CREATE,1 in your code yet.

OK, Tim, try this:


  • Be sure that you have threads OFF with INTERNET HTTP,1,THREADS,OFF
  • Make sure the file is fully downloaded before loading it into the list.
    That's what turning off threads will help with.
  • And as Hortalonus said, make sure that you use LIST CLOSE,1 if you are doing this more than once in your script.

If you have turned threads off in the VDSIPP extension, that event won't even be triggered. If you turn threads on, since you're using the INTERNET HTTP,DOWNLOAD command, you don't even need to have a routine for the HTTP1ONGETDONE event. You may need a routine for the HTTP1ONDOWNLOADDONE event depending on if you want to do anything when it is done downloading.

Could you publish the solution here?

So that we can all see how it was done?

here is what i did


Code:

 internet http,create,1
  internet http,threads,1,off
  internet http,protocol,1,1

etc


Code:

%%downloadsurl = http://www.whatever.com/whatever2.txt 

internet http,download,1,%%downloadsurl,c:\whatever\whatever2.txt 
%%dec100 = @Blowfish(DecryptFile,test,c:\whatever\whatever2.txt,c:\whatever\whatever.txt)
   LIST CREATE,1
  if @GREATER(@INTERNET(HTTP,CONTENT-LENGTH,1),0)
     list clear,L1
   LIST loadfile,L1,c:\whatever\whatever.txt
 else
rem do what ever you want if file is not found
list close,L1
end




i had this worng


Code:

  LIST loadfile,L1,c:\whatever\whatever.txt


i had this

Code:

 LIST loadfile,1,c:\whatever\whatever.txt


which was wrong for me...
