I am currently studying the most widely known encryption algorithms and methodologies. For practice purposes, I am currently pursuing a project where I just implement everything from ECB to RSA as some kind of a C crypto library.
I wanted to ask, how I would generate a more or less secure key in a C program (i know, that writing a crypto library on my own is not secure at all but I just want to learn basic principles from key generating to key exchanging to encryption mechanisms).
So, how could I approach the problem of implementing an algorithm for a secure key generation? Which main issues need to be considered to reach an at least mediocre key security?
Specifically, there is a character in the Curse of Strahd (p. 133):
Also, it’s worth pointing out that (from p. 119):
The only example I know of (in Curse of Strahd, at least) of an NPC statblock given to a non-human race is:
In the former case, no changes are specified at all, only an alignment and a race. In the second case, a few changes are made, but not enough to be a fully fledged member of that race.
It seems that, RAW, no changes are supposed to be made to these statblocks except those that are explicitly given, but I’m wondering whether there are any generic rules for NPC stat blocks that I’ve overlooked that state that such NPCs should be given the relevant ability score adjustments to match that NPC’s race, or any other racial traits as per the Player’s Handbook?
I am learning nmap scanning from beginning.
I tried to scan my office pc with the following command
nmap -sP -PP 192.168.1.104 --disable-arp-ping
and it works fine..It shows that 1 host is up
when I tried to scan for open ports then it shows errors.
I have used all commands like
nmap -sI etc but I can’t scan the host.
Actually my target pc is using Symantec antivirus and he is blocking my IP address because when I used to ping then it shows nothing.
I have a MikroTik router. I want to allow only Youtube videos and block all other videos. I tried to write an extended ACL but I really have no idea. Maybe allow only Youtube videos source URL and block other URLs? Can you guys help me?
Scenario: I have created a custom block that outputs a list of posts, with control over number of posts, and the taxonomies where the posts can be selected from.
The custom block is nested inside a custom “row” block, and further inside a core “column” block. The registered id of the custom block is e.g. ‘xx/dyno-list’
Need: I need to extract a list of the posts that have been assigned to the custom block via grabbing the data attached to each block, e.g. an array of posts.
Perhaps using something like:
wp.data.select('core/blocks').getBlockTypes('tr/dynamic-list') which does not work…
Each custom block has a unique “name” attribute, e.g. “block_one”, so I need to be able to grab the list of custom blocks, i.e. ‘xx/dyno-list’ and then grab the lists of posts within that specific block.
I need this so as to be able to “de-dupe” the posts list between custom post list blocks.
Question: How to grab a list of the custom blocks by their registered name and then by the attribute name
I’m not trained in Linux, but I think I found the solution to my problem documented, but it is not working as expected. I am NOT an iptables guru, I’m learning as I go.
A Russian IP is trying to hack my network, especially an email server I have running on my network. So I have a port forward of port 25 to the mail server machine. My router is running TomatoUSB – a Linux based router I have root ssh access to.
I’ve tried this command:
iptables -I INPUT -s 188.8.131.52 -j DROP
iptables -L -nv
returns a lot of stuff, and now at the very beginning looks like this:
Chain INPUT (policy DROP 9 packets, 504 bytes) pkts bytes target prot opt in out source destination 0 0 DROP all -- * * 184.108.40.206 0.0.0.0/0
This did not stop the traffic, though, as my email server is still reporting connection attempts from this IP address, so the rule is not dropping anything.
Perhaps the INPUT chain is not where I need to add this? I’m not yet educated on the different chains yet. INPUT intuitively seemed like the right place, but because this is a NAT router, should I really have some sort of rule in the FORWARD chain that can say not to forward to anyone if this is the source address?
Seems like what I want to do should not be difficult, but I’m struggling to figure this one out so far.
I want my party to avert a powerful wizard from becoming a lich. I know this can be done with a tome of darkness, and I’d like the party to destroy the tome of darkness in about three turns if two party members focus fire. The suggested state of items in the DMG makes a book comically easy to destroy, so I want some more magical tome that might survive longer. What’s a reasonable stat block to give it?
Is their an easy way to convert a vanila install with unencrypted root partition to an encrypted one (eg LUKS) in Ubuntu 16.04? I know that Android offers equivalent functionality, but am unaware of a “Linux” equivalent, and posit that this is OS specific and non-trivial.
I note the root filesystem is EXT4 and /boot is a seperate partition. I am aware of the possibility of backing up my data and reinstalling the OS, I’m just wondering if there is a more expedient way.
The Hieracosphinx is a lesser Sphinx that does not have an official stat block for 5e, as via Christopher Perkins’ Twitter. However, I would like to use this monster in a desert setting with Level 6 characters, for which the more powerful Gynosphinx (CR 11) and Androsphinx (CR 17) are out of question for being too powerful and not evil. In 3e, which I’m not at all familiar with, the Hieracosphinx had a CR of 5 apparently, see here, but I have no idea if I could translate the stats 1 to 1 into 5.
Another idea that I had was scaling up a Griffon (CR 2), giving it the Gynosphinx’s Claw Multiattack, a bit more HP and a few spells from the spell list.
So, what approach should I take here? I have never designed a monster from scratch before, only adding or subtracting 1 or 2 things from existing monsters sometimes.
