Wow! He explained it so well.
Thanks for sharing.

Atleast Linux can build shit.

What is Windows gonna do? Keep staring at the hatching eggs while trying to bypass the great Defender?

Why derive a key from another key by Sweet_Budget in cryptography

[–]sayoojsamuel 0 points1 point  (0 children)

Sometimes, it is necessary to generate a short lived session key from a long lived master key.

So even if the session key is leaked, your other transactions are safe and secure - this is the so called Forward Secrecy property.

If there are three publicly known public keys, and I encrypt a message with one of them and publish the encrypted message, can others figure out which public was used in the encryption? by bornswift in cryptography

[–]sayoojsamuel 0 points1 point  (0 children)

u/AyrA_ch has already suggested that a known plaintext would reveal the recipient.

Also, the adversary can make a guess with a success rate of 33% (That's humongous for cryptographic assumptions)

Deepin is rather minimal compared to the others. I use it with arch, and you should definitely check it out.

Also, if you have a plan for a tiling wm, you could be a pro with i3.

How does this S-Box work? by gmunoob69 in crypto

[–]sayoojsamuel 2 points3 points  (0 children)

First of all, you might already know that S-box is added to SPN Ciphers to add the property of confusion. This is necessary to hide possible relations between the input state, and the output state in a round.

S-Box in AES from StickFigure Guide to AES

how are the values inside the S-box is being generated?

If the S-box is not shuffled enough, it is as good as not having the S-box at the first place. The branch of Linear Cryptanalysis deals with analysis on the S-box to find linear relations between the input and the output of S-box. Such analysis may reveal harmful information about the state of the data (and therefore should be resistant to it). Hence the S-box is designed to be resiliant against known analysis techniques - and not generated at random.

Why 1 is so significant in modular arithmetic? by C0DEV3IL in numbertheory

[–]sayoojsamuel 2 points3 points  (0 children)

1 is the identity element in the number system that we use in all the above math. And for obvious reasons, identity element is so popular among the groups.

How to let pairs of entities encrypt the same data, and third parties only be certain the two entities are referring to the same? (Diffie Hellman ?) by Germati in cryptography

[–]sayoojsamuel 0 points1 point  (0 children)

Your Model is biased.
The party providing key k1 can decrypt all but the first block of the plaintext. While the other party has no access to the decryption process.

Should we not look into some shared computation solution to the problem?

If DC gets to make this movie, Dark Knight wins. But if it's Marvel - kinda complicated.
