Welcome back, fellow writers. Today I came up with a write-up. I'm gonna walk you through the Hackviser cryptanalysis writeup.
So, before starting the write-up, I will give a short intro to cryptography and cryptanalysis.
The cryptography process of encrypting the information through keys and encrypting text to be ciphertext.
Cryptanalysis is the breaking of the encryption algorithm with all possible techniques.
Encoding techniques are the process of transforming data into different formats for various reasons, like storage, security, and other reasons. Hashing techniques are used to transform data, such as passwords and other data converted into a fixed string. Unlike other techniques, hashing is irreversible.
Let’s go into the Encoding challenge.
ASCII challenge:
They have given an ASCII value; we have to decode the message.
