Encrypt/Decrypt Image Files

[Jean Christophe Avard]

Hi! I am designing an application wich comes with image file. These images
are copyrighted and they have to be accessible only from within the
application. At first, I tought I was going to store them in a database, but
since there will be much more than 2go, I'm going to need multiple database,
and it's no good for CPU performance...

I read about encrypting picture instead of storing them in a DB. But I only
found thing about string encryption... Has anyone of you ever had to
encrypt/decrypt image file? Anyone could point me a good tuorials or website
or anything???

Thank you, your help is really appreciated!

Re: Encrypt/Decrypt Image Files


yep me ,,,,,

even better i have a +- 3 gb of pictures and had to ship them on a DVD to
our customers in a somehow protected way
then i found the following solution

i was also searching for a way to group the picture files together in a
sort kind of library

then i found the solution in a nice opensource project
ICSharpCode.Sha rpZipLib.dll i downloaded the hole package ( comes as
compiled binary , source in C# with sharpdevelop project file , and
examples ) and explored the classes

i found that it is possible to create password protected library`s with
this dll , it works flawless for me i compress multiple files to one
password protected lib when i need to display the file i open the lib i
search the entry in the lib load it to a memstream and send it directly to
a picture box


to create a protected lib

Private Sub Button2_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button2.Click
Dim strDirnames() As String = Directory.GetDi rectories(txtSo urceDir.Text)

For Each strDirname As String In strDirnames

Dim astrFileNames() As String = Directory.GetFi les(strDirname)

Dim objCrc32 As New Crc32

Dim strmZipOutputSt ream As ZipOutputStream

strmZipOutputSt ream = New ZipOutputStream (File.Create("D :\compressed\" &
Path.GetFileNam e(strDirname) & ".cp"))

strmZipOutputSt ream.Password = "your own prefered password here"

strmZipOutputSt ream.SetLevel(6 )

REM Compression Level: 0-9

REM 0: no(Compression)

REM 9: maximum compression

Dim strFile As String

For Each strFile In astrFileNames

Dim strmFile As FileStream = File.OpenRead(s trFile)

Dim abyBuffer(strmF ile.Length - 1) As Byte

strmFile.Read(a byBuffer, 0, abyBuffer.Lengt h)

Dim objZipEntry As ZipEntry = New ZipEntry(strFil e)

objZipEntry.Dat eTime = DateTime.Now

objZipEntry.Siz e = strmFile.Length

strmFile.Close( )

objCrc32.Reset( )

objCrc32.Update (abyBuffer)

objZipEntry.Crc = objCrc32.Value

strmZipOutputSt ream.PutNextEnt ry(objZipEntry)

strmZipOutputSt ream.Write(abyB uffer, 0, abyBuffer.Lengt h)

Next

strmZipOutputSt ream.Finish()

strmZipOutputSt ream.Close()



Next




MessageBox.Show ("Operation complete")

End Sub

to extract a entry to a stream

Private Overloads Function Unzip(ByVal strSource As String, ByVal
strFileToExtrac t As String, ByRef newms As MemoryStream) As Boolean

If File.Exists(str Source) Then

Dim ZipStream As ZipInputStream

Try

ZipStream = New ZipInputStream( File.OpenRead(s trSource))

ZipStream.Passw ord = "your own prefered password here"

Dim TheEntry As ZipEntry = ZipStream.GetNe xtEntry()

Dim size As Integer

Do Until TheEntry Is Nothing

If Path.GetFileNam e(TheEntry.Name ) = strFileToExtrac t Then

Dim data(1024) As Byte

newms = New MemoryStream

Dim bw As New BinaryWriter(ne wms)

Dim buffer(1024) As Byte

Dim length As Integer

Dim dataToRead As Long = TheEntry.Size

While dataToRead > 0

length = ZipStream.Read( buffer, 0, 1024)

bw.Write(buffer , 0, length)

ReDim buffer(1024) ' Clear the buffer

dataToRead = dataToRead - length

End While

Return True

End If

TheEntry = ZipStream.GetNe xtEntry()

Loop

Catch e As Exception

Finally

ZipStream.Close ()

End Try

End If

End Function


example to put the stream in a picturebox as a picture

Dim newms As MemoryStream

MsgBox(Unzip("D :\AD.cp", "3DA3.gif", newms))

PictureBox1.Ima ge = Image.FromStrea m(newms)

well i hope this helped

Re: Encrypt/Decrypt Image Files

thank you dude!, is this all C# code? and where do I write this? in a text
file that I call file.DLL ???

Re: Encrypt/Decrypt Image Files

the code i provided is all VB.Net however the library i talk about is
written in C# ( it comes as source, and compiled dll )
you may download it here

http://www.icsharpcode.net/OpenSource/SharpZipLib/Default.aspx

it has examples in C# and VB.Net however the method i showed below to
create protected library`s is not in the examples i figured this out myself
by exploring the library

steps to take :

You download the sharpziblib library, set a reference to the dll in your
project , and you can start exploring


if you need any further help feel free to ask , i can write a small demo for
you ( if you have a newsreader that is capable of retrieving binary
atachments ,, like Outlook express for instance )

regards

Michel Posseth

Re: Encrypt/Decrypt Image Files

Thank you Michel, your help is really appreciated! I didn't know the REM
command, I thought that was C# or something complicated... though it's just
commenting haha, anyway. So with the code you provided, I can do all what I
need, encrypt and decrypt, I don't need anything else, well I'll give this a
try and let you know! Thanks again for this great help dude!! that is really
appreciated, I'm thankful!

Re: Encrypt/Decrypt Image Files

ok, have the code you gave me, I downloaded the ICSharpCode dll, I
referenced it inside my project. But now, when I type in "c:\12\" wich
contains "New Folder" wich contains 3 JPG, I get an error, saying "Size was
66, but I expected 5280262" I joined a screenshot of the error. Have you
ever come to this?

Re: Encrypt/Decrypt Image Files


strange ,,, no i never encountered this problem ....


i have sent you by e-mail ( to the adress you sent with to me ) a working
example

it shows how to create the libs , it shows how to extract a file out of the
lib , and it shows how to bind the stream to a picturebox control


regards

Michel Posseth
