Hope someone can help or have a free control. I am going to be passing
data from a client computer to a server via a winsock control. I want
to encrypt/decript the contents of the string that is passed back and
forth. Anyone have any ideas?

Ok, time to ask the question here.. I have been battling over this one for
sometime now and just have to ask it.
I have created a few classes that I use to act a security keys. These
classes get serialized using a binary formatter and then symmetrically
encrypted. The app will deserialize them and use the contents to judge
licensing capabilities, etc.
Currently the license key and vectors are stored in the code. I don't like
the idea...

I was in need of an encryption algorithm to the following requirements:
1) Must be capable of encrypting strings to a byte array, and decyrpting
back again to the same string
2) Must have the same algorithm work with strings that may or may not be
unicode
3) Number of bytes back must either be <= number of _TCHARs in *
sizeof(_TCHAR), or the relation between output size and input size can be
calculated simply. Has to take into account the...

Hi,
Does anyone have any simple text string encryption routines that are
easy to implement? I'm trying to prevent users and system
administrators from figuring out how I implement things.
thanks

this?

I made this class to encrypt my DataSet before saving it
to disk. So, first in the main program I write the
DataSet to XML in a MemoryStream. I pass this stream to
the E_File sub, which encrypts the stream and writes it
out to the FileStream. Now, in the D_File function, I
read the encrypted file into a FileStream, then decrypt
it into a MemoryStream, which I pass back to my DataSet
and Read the XML into the DataSet. The problem I'm...

Hi all,
I have an encryption class that encrypts and decrypts password using
TripleDESCryptoServiceProvider. It was written originally in framework
1.0 and been working fine. And those passwords are stored in my SQL
server.
Now I need to migrate my application to framework 2.0. I use this same
class with framework 2.0 library to decrypt the passwords from database
(of course, they were encrypted in 1.0) but getting "Bad Data"

program to C#. Well with the help with everyone I got it converted.
But I overlooked something and don't understand why it is doing this.
Below is my code, I would be greatfull if someone can guide me through
the right path or even help me solve this issue.
Problem: The old tool which was written in VB6 works perfect. But I

Another request for comments here.
I'd like to accomplish something like the scheme outlined at this page
here:
http://tinyurl.com/3dtcdr
In a nutshell, the form uses javascript to hash (md5) the password
field using a random one-time salt (nonce) -- generated by php and
pasted in the form -- that is then posted with the hashed password

I’m trying to encrypt and decrypt a file in vb.net. I am using the
TripleDESCryptoServiceProvider encryption found in
System.Security.Cryptography. Below is the code for my Encrypt and Decrypt
functions.
While my functions read and write files the encryption/decryption is not
working properly. My test file has an original length of 66,048 bytes. My
encrypted file ends up with 66,056 bytes … 8 bytes more than my original.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
