SHA256 and similar algorithms are insecure pieces of garbage.
Using SHA256 you gain no security against padding-oracle attacks (because you can't roll your own hash function), and you certainly don't gain any security against a rainbow table attack.
In fact, your security with SHA256 against a brute force attack will be a 1 in 2^32 chance that the hash is the correct value.
Insecure hash algorithms can't even provide a 128-bit security level against preimages (that is, if someone does a brute force attack against a SHA256 hash value, then that value is very likely to be a valid hash value that will yield a collision).
And there are ways to make hash functions that are actually more secure, because they take into account that a hash function will not always return the same value.
It is even possible to make hash functions that are significantly more secure than SHA256 against brute force attacks and preimage attacks, by using dedicated hardware and specialized, targeted, hash function design.

>The HTTP-01 challenge can only be done on port 80. Allowing clients to specify arbitrary ports would make the challenge less secure, and so it is not allowed by the ACME standard.
So the only reason to use the completely insecure retarded http acme challenge, ease of deployment, is completely invalid because you cannot simply have a script that runs a small http server, you have to disable your actual http server and only then you can solve the challenge?
The only fucking reason this garbage exists is so that glowies and cloudflare can trivially MITM all of your TLS traffic. Jewgle and all other big tech companies that are behind the root CA scam need to be disbanded and their leaders executed.
It's obvious that Let's Encrypt is a fucking op by the glowies. Just look at how they discourage manual certificate authorization by arbitrarily setting the expiration date of the certs to just 3 months. There is no reason to ever refresh your TLS cert every three months. But of course, they need to let the glowies in if they want to start MITM'ing your traffic so every three months, you need to provide unencrypted HTTP access to your server.

/fwt/ - Friendly Windows Thread

Users of all levels are welcome.
Share Windows tools, utilities, tips & tricks that enhance your life.
Reminder: Notice the friendly - please be civil.

>Installation for retards:

>Where can I get the ISOs?
>Where do I get Office?
>Can I change edition post-install?
Read the paste:
>Is Optimize-Offline worth it?
>Should I debloat?
Only if you understand everything that you're going to be intentionally breaking.
If something doesn't work later, you probably broke it with some debloat memescript.
>How do I activate?
HWID mimics OEM activation to generate a permanent legitimate license.
(Does not work on VL editions, avoid VL editions unless you enjoy having to deal with KMS breaking and Windows unactivating)

>>Which version should I get?
Comes preinstalled with bloatware apps like games, music, news, weather, etc.
Comes with system apps.
Comes with nothing, no apps, not even MS Store
Search LTSC-Add-MicrosoftStore if you need it.
There are no compatibility differences between versions, all programs/drivers will work on all versions of Windows.

LTSC meant for corporate PCs with 5 years security updates (KMS only).
IoT LTSC meant for retail/medical/etc PCs with 10 years security updates (HWID only).

>Do I even need LTSC?
W10 Home/Pro/Edu/WS/Ent editions are all EoL in 10/2025 (2027 for LTSC) whereas IoT LTSC will be supported until 2032.

>Is Windows 11 good?
>Should I upgrade?
Not yet.

>B-b-b-but muh Windows 7!
OpenShell or StartIsBack

I've got four months of free time until my MSc degree starts. I want to dedicate it all to mathematics and physics study. I'm willing to spend 18 hours a day working through mathematics, theoretical physics and computational physics.

I've heard that a lot of mathematicians and physicists throughout history have actually gone through hardcore routines like this (pic related). Anybody have any idea how these daily routines were structured?

Week 1 Plan:

[TPhys] Classical Mechanics.

Main topic: equations of motion. To include Generalised Co-ordinates, the principle of least action, Galilean relativity and the Lagrangian. Outlined in Landau&Lifschitz Vol1.
