Looking for Encryption/Compression .NET Component

[Mitchell Vincent]

As the subject suggests, I'm looking for a compression and encryption
component(s) for use with VB.NET. I would rather then be all managed code
but will use ActiveX/COM if I have to.. Price is important, the budget is
under $400 for both for a single developer license..

Any and all suggestions are welcome! Thanks!

Encryption:

See 'System.Cryptog raphy' namespace.

Compression:

The Zip, GZip, BZip2 and Tar Implementation For .NET
<URL:http://www.icsharpcode .net/OpenSource/SharpZipLib/>

The VB.NET Resource Kit contains zipping functionality too:

The Visual Basic .NET Resource Kit
<URL:http://msdn.microsoft. com/vbasic/vbrkit/>

It contains ComponentOne Zip for .NET:

Using J#'s zip functionality:

Re: Looking for Encryption/Compression .NET Component

About encryption - do it yourself. it's easy in .NET
about compression - google. there are couple of FREE compression
components, some of them managed.
for the payed ones, i've seen comersials of at least 50 managed and
countless unmanaged, just remove the word FREE from your search ;-)

could also add "-trial" to yout free search. this will block "free
trial" results ;-)

Re: Looking for Encryption/Compression .NET Component

There is a free piece of compression code on the 'Source Forge' Website
written in .NET (C# I think).

What Mr MVP said about the Component One stuff is an excellent idea!!
Download the VB.NET Resource kit, register it & then you will get a free
serial number to register all the component one objects. Make sure you keep
this serial number safe, as you won't be able to get another serial number
with the same e-mail address.

Another thing about the component one objects is that they are old (hence
they are free) & that was told to me by Tech Support at component one.

Mr MVP,

You said a few days ago that you never had a C# - VB.NET convertor, but you
have the VB.NET Resource kit which contains a free one.

Mitchell,

Never do encryption on your own when it is about security encryption. When
you built your own you are fully responsible.

When you are looking for only compression, than I found this zip very nice
and simple because it has a Net class to use.

http://www.gzip.org/zlib/

When you are looking for security encryption, than I would just start here.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemSecurityCryptography.asp

I hope this helps?

Cor

Re: Looking for Encryption/Compression .NET Component

But using .NET classes is not doing encryption on his own. The classes are
doing it. That is the whole point of the class is it not?

Re: Looking for Encryption/Compression .NET Component

Bob,

I have seen people here in these newsgroups asking how they could make an
encryption based on adding of a certain value to a byte array.

That is an example what I mean with doing encryption on your own.

Using a Microsoft class is that in my opinion not, because all the logic is
done in that class. In addition, with the encryption classes they give nice
explanations what technologies are used.

I assume that we mean the same, however I did like to explain this.

Re: Looking for Encryption/Compression .NET Component

oops. Yeah, that is what we both meant.

Another popular "encryption " method I have seen is the old XOR command.....

XOR encryption is very easy to implement, and in some cases it's sufficient
:-).

Re: Looking for Encryption/Compression .NET Component

XOR is a dreadful method for storing anything private. If developing on
..NET it would be crazy not to use the classes.

Re: Looking for Encryption/Compression .NET Component

For the encryption stuff, probably one of the most complete frameworks out
there is available as a part of Enterprise Library.

Hope that helps,

Well, simple XOR encryption only makes sense for making something
"unreadable " ;-). I agree, for "real" encryption, using the .NET
Framework's cryptography classes is the preferred way.

I never used the converter contained in the resource kit, but there are lots
of other C# -> VB.NET converters available:
