This is intended to be less predicable/have fewer correlations than
the default Mersenne Twister or Wichmann-Hill generators. Comments
are appreciated.

Hi!
Here's a simple hashcash implementation in Python.
28 lines of actual code.
Can be reduced to 17 lines for instructional purposes,
if you don't want clustering, and use xrange() instead
of irange().

I decided to write a pure Python hashcash implementation. I have seen
David McNab's Python implementation. Unfortunately, as near as I can
tell (which is supported on the hashcash mailing list archive), McNab
actually implements a different algorithm than hashcash. It might (or
might not) be equivalent in security; but I cannot see any directly
way to transform what he computes into an actual hashcash stamp.

Hello,
I try to compute SHA hashes for different files:
for root, dirs, files in os.walk(sys.argv):
for file in files:
path = os.path.join(root, file)
print path
f = open(path)
sha = sha.new(f.read())

This inquiry may either turn out to be about the suitability of the
SHA-1 (160 bit digest) for file identification, the sha function in
Python ... or about some error in my script. Any insight appreciated

Hello,
MSDN (amongst other places) is full of helpful advice on ways to do data
access, but they all seem geared to wards enterprise applications. Maybe
I'm in a minority, but I don't have those sorts of clients. Mine are all
small businesses whose sites will never reach those sorts of scales. I
deal with businesses whose sites get maybe a few hundred visitors per
day (some not even that much) and get no more than ten orders per day....

Operating system: Win XP
Vsn of Python: 2.4
Situation is this: Required to calcluate a message digest. The process
for calcluating the digest must use an SHA-256 algorithm.
Questions:
1) Is it correct that the sha module comes with python 2.4?
2) Is it correct that the sha module that ships with python 2.4 does
NOT have the SHA-256 capability as part of the module?

The Forms-encryption module includes a handy (if long-winded) hash function:
FormsAuthentication.HashPasswordForStoringInConfigFile
It only supports MD5 and SHA1, but ages ago MD5 was torn apart, and more
recently
(http://it.slashdot.org/article.pl?sid=07/01/20/1936257&threshold=2) they've
broken SHA-1, so obviously we're going to need something a little stronger.
I was thinking SHA-256, but that's too similar to SHA-1.
Fortunately I...

Hi, I'm trying to make the sha-1 algorithm based on the wikipedia pseudocode.
For the 'The quick brown fox jumps over the lazy dog" string I should get
2fd4e1c6 7a2d28fc ed849ee1 bb76e739 1b93eb12 but what I get is
1D8B8841 A544939A 98BB54FE 4C325476 C44AE1F0
(after I convert from dec to hex)
I have no idea what the problem is :(
Thx in advance

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

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
