Is there some sort of rule to determine how large a hash should be to ensure the security (meaning exactly one message maps to a given hash) of a message? Something that can be applied to any message, such as a 32-bit number or an 8-letter ASCII password.
I am currently working on a crypto challenge. Here I need to brute force a password. It’s SHA512 and the salt is given. But for some reason I can’t load the salt + hash into JTR because it’s complaining about the salt.
This is the salt + hash:
And I am trying to start the brute-force like so:
john --subformat=dynamic_81 --incremental=Alnum --min-length=5 --max-length=5 hash
dynamic_81 = SHA512($ salt.$ password)
If I remove the dashes from the salt, then it will load the hash. But the dashes are part of the salt so I can’t just remove them…
Does anyone know if I need to convert the salt somehow for JTR to accept it?
So I am currently running a game with 3 PCs, 2 of which are Elves and 1 a Human. I am just trying to calculate the most efficient way to run watch shifts during long rests since both of the elves only need 4 hour meditation to be considered fully rested.
In the PHB pg 168 in the section about long rests it states that (emphasis mine):
A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours.
Now my question is, once a character is considered fully rested and no longer needs the “long rest” are they able to keep effective watch for longer than a period of 2 hours? So say that the elves both finish their 4 hours, can they now keep a vigilant watch for the other 4 hours the human PC needs to rest?
I have gotten the code to do polynomial long division, but I want my students to also factor the solution if possible.
I’m interested in D&D 5e but I will also accept answers from previous D&D versions as well as similar systems (e.g., Pathfinder 1e/2e).
Janathiel II, famous historian, cartographer, and the Grand Wizard of Whitescar is studying the ancient structures of Ær-Toril known as Rhas.
These are gigantic and ancient structures/areas that cannot possibly have been created by nature. For example, Rhas Nolh is an almost perfect mountain pass that spans more than 100 kilometres, Rhas Aldhaen is an ancient forest that does not age (i.e., each tree is forever the same), etc.
Janathiel II has a theory: All of the Rhas constructs were created approximately during the same time period/era possibly by a technologically/magically advanced civilization.
To test this theory, however, he needs an accurate way of measuring how old an object is. Even worse, this method should be accurate even when counting thousands of years (if not hundreds of thousands).
If Janathiel II was living on Earth during the 21st century he could have used radiocarbon dating, but unfortunately for him, he lives in Ær-Toril.
Is there a spell, magical item, or any other method Janathiel II can use to accurately calculate how long ago an object/construct was created?
I’m designing a web app where the user adds predefined items from List A to a custom List B.
List A is over 100 items sorted alphabetically.
List B can be customized according to user needs.
I designed a drag-and-drop solution for the web app. The user can jump to List A items alphabetically by clicking a letter.
This drag-and-drop feature doesn’t work on tablets very well and is impossible for smartphones. So I designed a select form for mobile devices: When the user taps on a list item in List B, a picker/flipper populated with List A items is triggered.
Is there a way to implement alphabetical filtering in a web app’s mobile interface?
How can the mobile interface for this feature solve the following requirements?
- Allow user filter List A
- Add items from List A to List B
Hi in my app user can select an item in a long pre-defined list to add to the user owned list. The user’s list therefore may have hundred of items. The user must be able to see what items are in his / her list and remove items from the list as well. The list works exactly like how you would compose an email on Google mail and add people the to recipient list. How can I effectively do this. Thanks.
I am planning a short campaign in DnD 5e that starts out with my players imprisoned upon an airship. The airship gets attacked, and all passengers are hurled towards the ground from a substantial height (more than 3000ft).
A few key points:
- These are 16th-level characters (because we want to do a high-level adventure). I won’t tell my players that they “should” or “might take” magical starting equipment or spells that give them flying speed etc.
- They are stripped of their equipment (because they were imprisoned, by even stronger characters)
- the fall should be lethal, if they do not intervene. I’m considering moving the damage cap for falling up for this very reason (I plan to use the “a creature falls 500 ft at the start of a round” rule). I want to avoid the “raging barbarian just fell out of the sky and just tanks the impact” scenario, if possible.
My current ideas are as follows:
- the cargo from the ship – that contains their equipment, which they can recover later in the campaign – also includes Scrolls of Feather Fall. The scrolls are scattered in the air around them and can be grabbed and used. This has the caveat that Feather Fall is only on the Bard’s, Sorcerer’s, and Wizard’s spell list, so if we don’t have one player with this class, RAW they cannot read this scroll
- a player could grab a sail from the airship and use it as a improvised parachute – this is probably far out of the rules, but I might rule this as a DC 20 Acrobatics or Athletics check?
- the players can attempt to fall into water, a lake or something similar. This will reduce their damage, but might still kill them.
So, are there any good solutions for this scenario that – work for (almost) all classes or – let one player save the whole party or – somehow negate the fall damage otherwise?
For example an email address for one area of the company is something like “firstname.lastname@example.org”
Though we can do many alternatives (links, forms etc.) so you don’t see this long contact, we’ve found that people want to know where it’s going.
The longer contact address proves a challenge on mobile and in different components of the page.
Where’s a good breakpoint for email?
What’s an alternative approach when you have to display a really long single word?
I’m redoing a web configuration UI for a piece of hardware. Think of a configuration UI of a standard router. You install this hardware into your network and access configuration through your browser. The UI will normally be accessed from PC and should also be available for mobile devices, but PC is definitely in a focus here.
I need to implement a configuration form with a submit button. The old design was done in material design and had this layout:
Form1, Form2 are a bit different configuration forms, that have a similar topic (Currently active SubMenu1). Think of “IP Address”, “Router Name”, “DHCP Configuration” etc. if it was a router. All of these have the same Submit button in the right top corner that applies only the changed inputs. For example if there is an input for a password, it will be applied only if it was changed, otherwise, the old password stays even though the input was empty. The submit button, although located on a menu bar is floating (when the menu bar is not) and always stays on the screen in exactly the same location when you scroll.
I’m redoing a UI similarly, preserving looks more or less, but changing the forms to be grouped in cards instead:
But I’m hesitant to use the same location for Submit button, as I believe there are serious issues with it from UI/UX perspective.
- The location is extremely weird and unintuitive. The button is located on the menu that is common for all views and simply appears/disappears depending on the view. Users do not expect it to be there
- The button although located on the menu is not attached to it and floats when menu is not.
- It is not obvious that if you do not change the password input and leave it empty, the password is not changed. My first thought is that this submits an empty password to the system. However, I’m not 100% sure this is a problem, just find it weird.
The problem is I do not know where to put submit button here. My first guess it to make it floating and to put it in the lower right corner. I do not know how to fix the password problem though.
Is this a good suggestion? If not what should I do? And is this a good idea to leave the password box as is, or it needs to be changed?
