How would you code a program ( preferably in Java or Python ) to break a random ciphertext where key can't be determined by shifts i.e the key substit ...
I started to learn rainbow tables and I have a question : How we can find a plaintext of hash if we delete all chain except first and end plaintext If ...
I have two message: I need to find SHA256 partially collision of these two messages(8 digits). Therefore, The first 8 digests of SHA256(messageA) = ...
Given then plain text, the encrypted text and the keyword length I am called to find the cipher key using brute force attack. What I did was to take t ...
I am studying a problem which reduces to the cryptanalysis of a lengthy monoalphabetic substitution ciphertext written in a known language. This probl ...
I'm writing a program that will calulate the private key for a weak RSA public key. I am wondering how I would go about determining the values for p a ...
I have this function that I have significantly simplified that calculates the multiplicative and additive keys for decrypting an affine cipher and it ...
I have to create a function that takes input as letters from a frequency analysis of the English language, "p1" and "p2", as well as a frequency analy ...
I am trying to calculate something like this: a^b mod c, where all three numbers are large. Things I've tried: Python's pow() function is taking ...
I am only learning c and I am trying to implement a for loop from an algorithm. I am so so confused in how to implement it, please see my attempt belo ...
Suppose I was given a string that looks completely garbage, and I am asked to identify what it could possibly be, there are tell-tale signs that crypt ...
How can I write Vigenere cryptanalysis for persian language? Is there any sample source code for persian? ...
I have to implement the following algorithm which will be run a few zillion times in the cryptanalysis of a specific cipher, by hill-climbing. The alg ...
I've got a HashMap which stores the frequencies of each letter in a block of ciphertext, in the form of Character, Integer. The map is then sorted int ...
I'm trying to implement a particle swarm optimization algorithm for a cryptanalysis local search to find the key of a simple substitution cipher. I u ...
I am trying to use this ECDSA implementation in Haskell, if you look at line 15, you will see that the k value uses randomRIO which uses the global ra ...
So, we're told to not use the same key for one-time pad, because if an attacker knows the two cipher texts, he can get the XOR of the two plain texts. ...
I am looking for tools (preferably free) to practice various cryptoanalysis and cryptography techniques. Something along the lines of following two on ...
These days, I am working in the field of cryptanalysis and have started to do programming with C# Now, For finding the 5 optimal s-boxes(i mean thos ...
