I made an android app to get you into basic cryptography.

It has puzzles as well as an encrypt / decrypt feature. It only references the basic ciphers for now but I'll be adding more in the future if the app picks up.

You can get it on Play Store :

Is Applied Cryptography by Bruce Schneier out of date?

Hello everyone,

I ordered this book(the 2015 edition) because it was recommended to us by our professor and I see now that quite a few people say it's out of date.

Is this true? And if it is, is it so out of date that it's actually bad for someone who is just starting to get into this world, or is it still going to give me valuable knowledge?

Help me remember the name of a cryptography creation toolkit

Hey all,

Long ago I encountered a library that helps developer create cryptosystems. The idea was that it contained a base of simple things that can be utilized to write your own crypto algos.

It wasn't libsodium or NaCL or something else, it marketed itself as an open source toolkit to help implement cryptography.

Does anyone know the name? Thanks!

Help solving a linear algebra cryptography problem

Hello, I'm studying for an exam in Linear Algebra and I can't for the life of me figure out what I'm doing wrong on a cryptography question. Here is the question and each letter is assigned to these numbers.

Find A^-1 to decode the cryptogram. 

    A = [1 -1 0] 
        [1 0 -1] 
        [-6 2 3]

Message: 15, 18, -107, 14, 5, -57, 14, 10, -72, -6, 13, -42, 20, 7, -81, 8, 19, -94, 7, 12, -62
A = 1, B = 2, ..., Z = 26

A^-1 is

[-2 -3 -1] 
[-3 -3 -1] 
[-2 -4 -1]. 

To find the answer, it should be as simple as Message * A^-1 (The message matrix multiplied by the matrix A^-1 ). The answer I get is wrong

[130 329 74] 
[71  171 38]
[86  216 48]
[57  147 35]
[101 243 54]
[115 295 67]
[74  191 43]. 

However, this does not coincide with the numbers given. None of the numbers are in the 0-26 range. I recognize A, as well. It's the exact same matrix that was on our 1st exam and practice exam. Now the matrix isn't working. Does anyone know what the issue might be? Is there something I'm misunderstanding about cryptography or is there simply an error?

Edit: I will a post a picture of previous questions with the same matrix but different message soon.

Edit2: Previous problems

Edit3: Formatting

Edit4: My professor messed up on the problem..

volunteer teaching cryptography ?

Hello !

I'm a high-school senior who likes messing around with cryptography. I've completed a four part course on cryptography and written a math paper on the RSA so I guess I know enough to find the field fascinating.

I'm working with local ngos to conduct a winter break program for low income high schoolers. These kind of programs are something I never had the means to attend myself and I want to make it happen for them.

The essence of the program is to give kids the opportunity to learn cool shit. And that's where cryptography fits in.

For those of you with adequate knowledge on the topic. Would you like to volunteering online to help teach them ? It would be for two- three hours a day, for five days.

Let me know if you're interested and we can discuss some more details !!

Cryptography book

Hey guys, I'm looking for a book (made out of paper, not digital) about (just throwing some keywords):

  • Cryptography
  • Encryption (symmetric and asymmetric)
  • hash algorithms (both fast for checksum and slow for passwords)
  • applications of the above (SSL, email, credit cards, ...)

I want the main focus about the exact mathematics involved in these algorithms. And maybe something about the best practices in reality. But since this topic is around for decades, the book does not have to be super-up-to-dace.

Edit because people were asking: I have a masters degree in technical mathematics. But not a big background in CS or software dev

Thank you guys in advance :)

[HIRING] Content writer with good cryptography/tls/ssl/security knowledge to extend current content. SEO and keyword research will be needed.

Hello,

I am looking for an INDIVIDUAL to do some content writing.

I would like between 10-20 pages content to be extended, to make the pages longer and better. And more is possible.

You MUST have good knowledge of how TLS/SSL Certificates work, and be somewhat familiar with brands such as Comodo/Sectigo/GeoTrust/DigiCert.

You will also need to do a bit of keyword research to see what some good target keywords to add into the content is.

I will pay between $40 to $60 USD per page done. Depending on the quality and length.

You WILL need to prove you have the needed knowledge, you can show some examples of work, or just talk to me and tell me what you know.

You WILL need to show me some examples of your work.

I will provide to you one page to do before we decide on you doing all of them, so i can be confident in your abilities. Some may not like to do this ( as i will not pay unless it's good quality and usable), but sorry, this is a requirement. If your confident in your ability then there will be no problems. And if all is good, i will pay for the work, and you will get the job.

I will do NOT wish to talk to anyone who is from an agency. I want to work with ONLY an individual.

If you believe you have all of the above, please contact me.

Getting into cryptography

I'm in my first year of university doing a 3 year course for Maths, however I would like to have a career more towards computer science. Someone suggested cryptography to me and I am quite interested in it. I was wondering how I could actually get into cryptography, as I don't really know where to start. The only thing I've done that is somewhat close is learning python (my course requires me to do so anyway, and I may learn Java just on the side if I have nothing to do).

Will/Should cryptography be abolished in an Anarchist society?

If someone encrypt some data and keep password secret, this gives they exclusive access to the data and seize other people's liberty of accessing it, which forms a power hierarchy (very much like how material private property work). Now, is there a way to justify this power hierarchy? If not, will encryption be obsolete in an Anarchist society?

Why do Yubikeys use symmetric key cryptography?

Hi,

Crypto noob here, I've been reading this post by Yubico on how OTPs are generated. I'm curious as to why symmetric key cryptography was selected to generate the OTP. If Yubico's servers are hacked, the hacker would be able to generate spoofed OTPs for any user. This problem seems to be avoided if public key crypto is used, and Yubico stores only public keys instead of AES keys.
