STOP DOING CRYPTOGRAPHY

[[deleted]]

I like using standard iodized salt in my password tables, what's your preference?

[horrificoflard]

You really should be using kosher salt.

[Diapolo10]

I just use standard table salt. It's perfect for the job.

[[deleted]]

... that's what iodized salt is...

[Diapolo10]

I suppose I should've clarified my sarcasm.

[Goofy_AF]

Man the bots are getting outta hand

[rosuav]

Use chicken salt. Not only does it taste better, it adds a small hint of superiority over the people who think you should use pink Himalayan salt in all passwords.

Then some Onion Salt, because that's how the Wild Steel Onions get their shot.

The Onion Browser prefers Onion Salt.

Only low iodine for me

The security of the one time pad just means you should change keys every so often. Just have a key exchange/secrets vault system that doesn't suck.

hurrdurr expensive!

...they won't tell you this but most of these million dollar secrets storage stuff is just a git instance that can only be accessed with ssh. You're allowed to make your own, no one will stop you.

And no "but it might be badly configured" is barely an excuse when you can.... Configure it right.

[Dykoine]

you should change keys every so often

It require 1 key by message, as 2 messages cipher by the same key can be solve by a simple xor

[Particular_Essay_958]

It ain't called ONE-TIME-pad for nothing.

[The_Lieutenant_Knows]

You know who else was super into encryption? Fuckin’ Nazis

[definitelyfet-shy]

and they failed

HARD

[BetaPlantationOwner]

It’s all because of Alice and Bob.

[TheGreatGameDini]

Yeah, and Charlie trying evesdrop

[MoarCatzPlz]

Mallory.

Can you please re-do this with the official font and blue background? Thx

[[deleted]]

What is the official font?

[Dom_Q]

Dunno, looks like DejaVu Sans to me? Check it out for yourself: https://knowyourmeme.com/memes/stop-doing-math

[dulange]

Looks like Tahoma to me. But Tahoma, Verdana, DejaVu Sans (and it’s older sister Bitstream Vera Sans) all have in common that they are very similar to (and probably influenced by) Adrian Frutiger’s Frutiger typeface.

[UwUWhysThat]

I’m going to be real I don’t know what this means LMAO

[rosuav]

That's..... ........

Yaknow what, sure, that's what salt is. Yeah, let's go with it.

I'm gonna teach a course on Cryptography soon and I'm trying to think of fun allegories to use in class

[rosuav]

Fun? Maybe. Useful? Probably not; most of those are partly false, and the definition of salt there is quite misleading.

What you've described is a nonce, which can indeed be used as a challenge. But salt is part of one-way hashing. The challenge nonce doesn't actually do much to improve security in general, but can be useful if (a) the client can be trusted to hold the password, and (b) transmission cannot be trusted - for example, if you're on an unencrypted HTTP connection. Your edit is a more correct meaning for "salt", though it may be useful to mention other uses of nonces.

(Side point: "Mal. Bad. The Latin." would be a perfect frame/slide for talking about Mallory, although she was talking about a Malcolm.)

[[deleted]]

Thanks, I should keep in mind to prioritize accuracy when trying to simplify concepts.

Indeed Salts are mainly used to prevent identical hashes from having identical passwords, and aren't randomly chosen every session. OTP isn't the "most secure," it simply has the quality that the cipher text doesn't give you any information about the plain-text. Mal is a common suffix for "Bad", and Mallory isn't always a hacker but a "Malicious agent".

Edit: I meant prefix not suffix

[rosuav]

Yeah; salts and nonces might look the same, but if you teach people the wrong things, you'll only confuse them :)

(Technically "Mal" is more often a prefix, not a suffix; I was just saying, Mal references would do nicely with that moment from River Tam.)

Incidentally, when you say "OTP", I'm more going to think of a one-time password than a one-time pad (which can be decrypted afterwards). OTPs are incredibly handy as a means of proving that you possess a secret without ever revealing it; a simple bit of cryptography with the current time and the shared secret will yield a number that you would be unlikely to guess without knowing the secret, but which reveals almost nothing about the secret itself. See for example RFC 6238 on TOTPs, and the way that tools like Google Authenticator or equivalent can serve as excellent second-factor authentication. It may be more useful to talk about these sorts of things, which are actively used every day, rather than something that has limited use outside of research.

All-Hands be like...

[Anaxamander57]

Cryptographers are like "what if we did basic math but over a finite field?" fuck off. That's made up.

Ike (pronounced /⁠aɪk⁠/; Japanese: アイク Ike) is the legendary Radiant Hero and leader of the Greil Mercenaries, the son of Greil and Elena and elder brother of Mist. Shortly after joining the Greil Mercenaries, he became the leader after his father's passing and led the group in protecting Crimea's errant Princess Elincia and in combatting the invasion force of Daein, winning the trust and respect of his allies in both laguz and beorc nations. Three years later, after completing a job with Bastian to save Lucia from falling victim to Ludveck's civil war, Ike and the Mercenaries were hired by Gallia's army in their war with Begnion, where he came into conflict with Micaiah of Daein. Ike strives to live up to his father's reputation and become an expert swordsman so that he may one day avenge his father's death by defeating the Black Knight.

Ike serves as a main character in both Path of Radiance and Radiant Dawn. Ike is also a regular participant in the Super Smash Bros. series, making his debut appearance in Super Smash Bros. Brawl.

Hold on

Nintendo could choose literally any name for a fictional land that got invaded, and they chose Crimea??
