I'm not very familiar with C, so I would like to ask you how can use
the algorithm Rijndael, suppousing that I want two simple functions (in C ANSI)
implementing the CBC or ECB Modes (is the same for me, because I have
both implementations in Delphi, but i need the same implementations in
C for an AS400) with an interface similiar to this (in Object Pascal):
function Encrypt(PlainText: string; Key: string): string

I have a client / server application. I just want to encrypt small amounts
of data 1<x<1024 characters or so. I need to load the same Key and IV in
both applications. However, both the key and IV are byte arrays.
What is the best way to get the keys loaded in both applications?
For example in RSA you can export the keys to XML. Can you do this in
Rijndael? I tried using System.Text.Encoding.UTF8 or ASCII, but this does
not appear...

Hi
I have a couple of encryption methods but when I call decrypt I get the
string back but with a load \0 escape characters on the end?
Any idea why? It is actually causing problems in some places, here are my
methods:
public static string Encrypt(string input, byte key, byte iv)

The old one, not the .NET version. I don't see it listed, but since
it's available under .NET I thought I'd ask. Also, there are some API
calls which are supposedly not available under most Windows
installations (CryptBinaryToString, for example). I don't suppose this
has changed? Basically, I'm trying to replicate the functionality of
some .NET crypto stuff in C++ and finding that some of the stuff I need
isn't available.

Anybody has any idea why this simple thing is not working? I pass a text
file as input to encrypt it, then pass the encrypted version to the same
function and get some garbled data not at all resembling the input file.
Rijndael rijndaelAlg = Rijndael.Create();
rijndaelAlg.BlockSize = 128; // 128 bits to comply with AES
rijndaelAlg.Padding = PaddingMode.PKCS7;

Hello,
I try to program a Rijndael encryption in Windows which has to be
compatible with php.
In php I use the code below to encrypt with a 256 Bit Key and a 256 Bit
block cipher.
My windows code has the same specs, but the outcome is different.
So far I use no iv to facilitate.

The 2.0 Framework SDK only has examples where the Rijndael class instance
provides the key. I've tried setting my own key value, making sure my key
length matches the KeySize property of my Rijndael instance. I always get
"invalid key". Am I misunderstanding the concept - if I don't set and keep
my own key, how will I be able to decrypt later? Any ideas or example would
be much appreciated.

According to this link, I am using Rijndael Encryption & Decryption
Algorithms, But I want my encrypted strings just CAPS string and just
alphanumeric values ABC...Z and 123...90, no other chars I want, what should
I do ? or what other algos I must use,
Thanks

Who can help? I'm trying to implement an encrypted (plain text)
communication between a Delphi application and an ASP.NET. My choice
is AES/rijndael-128. For both sides, i use standard modules:
Delphi: TDCP_rijndael Component (DCPcrypt Cryptographic Component
Library v2) from cityinthesky (www.cityinthesky.com)
ASP.NET : Standard library of Rijndael
both sides are working, BUT they do different! The results in encryption

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
