    You have perfect skills in the C programming language? You know that Grub2 is a bootloader and you have used it before? You know Cryptsetup and cryptography is not foreign to you? You know how to use Git? Grub2 supports mounting encrypted disks (LUKS2) with PBKDF2. However, PBKDF2 is a rather weak encryption. Encryption using Argon2 would be better. To avoid reinventing the wheel, this task can be accomplished using the code from the open source tool Cryptsetup. Basically, you need to look at Cryptsetup and implement Argon2 in Grub2.

    Write a program that runs the birthday attack against a hash function defined next. This hash function is called “BadHash40” – it is constructed using SHA256 as a subroutine. Specifically, BadHash40(x) := SHA256(x)[1..40], i.e., it takes the first 40 bits of the output of SHA256. The construction of BadHash40 is illustrated in the following figure: Your task is to find two (arbitrary) inputs to the function BadHash40 which result in the same output, i.e., to search for a collision in BadHash40. Your program must compute such the two inputs and the corresponding output for BadHash40; use the hex format when reporting all these values. Your program must write the list of random messages mi and their corresponding hash values ti into a text file (use t...
