Not OP but this is how I learned it and how it’s presented in the help file.

$ help while
while: while COMMANDS; do COMMANDS-2; done

$ help if
if: if COMMANDS; then COMMANDS; [ elif COMMANDS; then COMMANDS; ]... [ else COMMANDS; ] fi

The -k argument on my openssl accepts a passphrase, not a file. You likely encrypted with the filename as the secret, not it’s contents. Perhaps you should use -kfile instead.

$ openssl aes-256-cbc -help
Usage: aes-256-cbc [options]

General options:
 -help               Display this summary
 -list               List ciphers
 -ciphers            Alias for -list
 -e                  Encrypt
 -d                  Decrypt
 -p                  Print the iv/key
 -P                  Print the iv/key and exit
 -engine val         Use engine, possibly a hardware device

Input options:
 -in infile          Input file
** -k val              Passphrase**
 -kfile infile       Read passphrase from file

As an aside, these are the client logs, check the /var/log/ auth.log or secure files or journalctl to see if the server logged why the access was denied.

You seem to be misinformed on how the internet works. Nothing is “free”. ISPs have to buy equipment, pay for expensive physical connectivity (without disturbing existing infrastructure), and usually have to deal with constant, ever increasing bandwidth requirements.

I’m all for a bit of net neutrality, but ISPs tend to get a lot of flak for policies like this, for seemingly no reason. For example, let’s say ISP A and Upstream B have a mutual bandwidth sharing policy (called Peering) where both sides benefit equally from the connectivity. ISP A determines that N is using all the bandwidth to Upstream B. ISP A has three options: N gets all the bandwidth to Upstream B (disturbing other traffic to/from that network), N has to be throttled to allow all traffic equally, or ISP A and Upstream B need to expand their network again (new equipment, new physical links) which will cost a lot of money. N doesn’t even pay ISP A or Upstream B, they just pay their ISP C. In the end, ISP A has to throttle N, and N is the one who had to expand/change their business model to deliver content to their customers. They had to go out and buy services from many upstream providers to even the load and designed a solution to install Caching boxes inside each ISP’s datacenter so their traffic could reach end users without going upstream.

Yes, but as I’ve found recently AES-NI is only as good as your software support for it. Had a team using an ancient version of winscp and they kept complaining about download speeds on our 10Gb circuit. Couldn’t replicate it on any other machine with the newest version of winscp so I installed their exact version. AES-NI support wasn’t added until like 2020 and it gave them 5x better download speed after upgrading.

Does cryptsetup/luks do that? I thought that was only software encryption.

You can, sure, but you probably shouldn’t. Encrypting and decrypting consume additional cpu time, and you won’t gain much in terms of security.

Hover over the window in the task bar and right click on the preview. This should show the restore/minimize/maximize dialog. Click restore if it’s an option then do the same and click move. You should be able to then use the arrow keys and “attach” the window to your mouse and move it to the visible area.

Edit: the other way to get this menu depends on the application but if you select the window and hit ALT and then space it should show the restore/minimize/maximize options.
