In an ideal encryption, the resulting data should be indistinguishable from random when doing statistical analysis.

So yes, such data will be really hard to compress, so typically compression is done before encryption.

Now here’s a twist. The compression before encryption can reveal some details about the encrypted data. This is especially true if attacker has a way to generate encrypted message with part of information that is being encrypted (for example some kind of token etc).
There were attacks on it. For example https://en.wikipedia.org/wiki/CRIME or https://en.wikipedia.org/wiki/BREACH (this was during that idiotic phase where vulnerabilities had those lame-ass names and they even created webpages)

Ideally compression would be done after encryption, but because of issues described earlier, that wouldn’t give any benefit.

Well there’s small chance someone else could get your mail, also there’s a reputation of given IP + there are blacklists that list dynamic IP ranges and some servers outright block them. And last one, you can’t set your own reverse DNS, which could increase like hood ending up in spam folder.

I did not, but it looks interesting, thanks

I use fail2ban and add detection (for example I noticed that after I implemented it for ssh, they started using SMTP for brute force, so had to add that one as well.

I also have another rule that observes fail2ban log and adds repeated offenders to a long term black list.

I think this might answer your question: https://chrisdown.name/2018/01/02/in-defence-of-swap.html (especially the tunning section)

I’m one of those people.

This is a nice read from a kernel developer responsible for memory management.

Don’t use Ubuntu, but are you sure it removed it and didn’t do the same thing windows does (i. e. hybrid suspend, where it does the same as hibernating, but then enters suspend, so if power is cut you still have your ram preserved)?

I self host through my ISP connection.

I have static IP and needed to get a business plan to obtain it. I am actually wondering if there’s place where I can set up a tunnel (that would work with freebsd) and then I could use cheaper, customer based plan.

My problem is to get something that wasn’t abused by spammers. I don’t plan to send any advertising, it would be low volume, since it is just for my and my family.
