comment Is the HMAC weakened if a part of the message is part the key?
TL;DR: No but it's useless. Just leave the message out of the key.

comment Encrypting a huffman encoded file
Encrypt the whole file. The contents do not matter and you want to leak as little info to an attacker as possible. In fact I wouldn't be surprised if you could figure out the file's contents under the right circumstances when leaving the header exposed. I cannot think of a single advantage to leaving anything exposed. For encryption, use something like GCM (galois/counter mode), or if that's unavailable try for AES-256-CTR, or AES-256-CBC. Tip: use a library. (Yeah this comment might be good enough for an answer, but it's just jotting down thoughts.)

comment Hackers attack against wp-config.php
@JaneBrye in that case I think someone might be abusing your hosting account for spam or DDoS attacks or something. Without more details I can't really say anything, but one way to stop it is change hosting and do a fresh Wordpress install. Or have someone look at it.. perhaps the hosting company can look through logs? It's in their interest not to end up on blacklists.

comment What sensitive information can be leaked in a Vim's swap file?
Hmm, good point. I edit stuff on a live website with vim, but never thought about the swp files that might leak parts of the content... The odds are low that someone will try whether the swp file is present right at the moment when I'm editing, but it's a good point nevertheless.

comment Should expired compromised certificates be taken care of if the time is always correct?
"It's your server that should check the validity of the certificate not the web client." I think this is the most important remark here. The server is something you control and which usually has a somewhat-correct time (not off by weeks at least).

comment Can my workplace view my Tor traffic?
"just connecting to the network" won't allow them to run code on your computer. That's what we call an RCE and is considered a security vulnerability if software allows it. Sysadmins can only run scripts on Windows remotely because the system was connected to the active directory by an administrator earlier; you can't just run code on anyone connected to your WiFi network. That would be, well, either lots of fun or hell, depending on which end you're on.
