I Have a .NET program sending mails using CDOEX.
These mail I need to sign. I god a tip that i shoud use CAPICOM. That worked
fine sending a mail with signature.
BUT the problem is that I have to type the password for my certificate every
time my program signs a mail :o(
My program is a windows service running on a server so typing passwords is
bad.

Hi,
A Java application is encrypting a block of text using 3DES ECB mode
and PKCS5 padding. I need to decrypt this text using C#. I've
extracted the 192 bit key using the getEncoded() method of the
SecretKey Java class. However when I use this key in .NET i cannot
decrypt the cipher text.
I am pretty sure that all my settings are correct, as far as setting
the ECB mode, PKCS5 padding and converting the cipher text to byte

Hi
i have a question regarding the CryptoAPI.
I can seemingly call CryptAcquireContext, and if I pass any random string as
the key container name and NULL as the provider name, with CRYPT_NEWKEYSET
as the last parameter, then the rest of the crypt functions seem to work.
But I came across an instance when I stopped debugging the program, before I
had called CryptReleaseContext, and when I ran the program again, I got
FALSE returned, and...

This is a very weird problem, when I boot my IIS server I get a CryptoAPI
cryptographic service provider (CSP) for this implementation could not be
acquired exception. However, once I access my site within the server, the
exception goes away. My ASP page only displays the logon user (only 2 lines
of code). I don't understand this behavior at all.

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...

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,...

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...
