@JohnZhau Not really anywhere, because cryptography is to steganography like a VW Golf is to a unicycle. One is a very practical tool, the other is mostly for show
In all seriousness, steganography is used if an adversary must not know that communication is even happening between two parties. This is not a requirement many people have
And those who do usually have the ability to send "binary" messages, e.g. the presence or absence of an object indicates status 1 or 2.
A good example was the root beer incident, where I think the CIA (don't quote me on that though please) was communicating with a russian traitor and they said if the operation is a go, he should put a can of beer on the table outside of his apartment.
What happened? He put a can of root beer there, and everyone was discussing if root beer was a beer (which it is not) and if he just made a mistake assuming root beer is beer because it says beer.
But even here, a simple "yes/no" answer sufficed.
As for arch, just look at the arch wiki. Though in all honesty, this should be more a passion project than something for productive use. The first few months after setting up Arch you won't get anything done. And afterwards, well...not really either
And I'm sure there is like one Arch user here who got Wifi to work on his system and would love to complain about it here, but his command-line browser does not support JavaScript so he can't reply.
As for BitLocker, it depends entirely on how it is set up.
The problem with Microsoft is that they want to use recognizable names, but those names mean different things in different contexts. Outlook for example used to be a simple mail program, but now it's more of a cloud-service thingy in addition to that.
As for BitLocker, there is such a thing called transparent mode, which was supposed to be the best user experience. Keys are stored in TPM, so you as user don't need anything to decrypt it.
The problem is that this offers literally no security. Like a door that tries to be "more usable" by opening as soon as you touch it.
But other modes, specifically those based on 20-digit passwords are pretty secure.
And yes, decryption takes a long time because it needs to decrypt a whole hard drive. The reason why it does not take ages to use your PC with bitlocker is because it uses AES-XTS, which is a special mode that allows you to start decrypting on any block and just decrypt the blocks you need
When disabling BitLocker however, you need to decrypt the whole hard drive, which takes a long time.
