Error Correction Codes
In this problem, you will examine why techniques that work nicely for error correction codes are notsuited as cryptographic hash functions. You will look at a hash function that computes an 8-bit hashvalue by applying the following equation:Ci=bi1?bi2?bi3?bi4?bi5?bi6?bi7?bi8Every block of 8 bits constitutes an ASCII encoded character.a. Encode the string CRYPTO to its binary or hexadecimal representation.b. Calculate the (6-bit long) hash value of the character string using the previously define
