DiceCTF is an annual CTF competition prepared by @dicegangctf. The challenges are great and we had a lot of fun solving them. I might be compiling writeup for a number of them, which depends if I had time. Deja vu? I said similar things last year. Until now, part 2 of my writeup series on DiceCTF 2021 does not exist. I will first cover on a crypto challenge called commitment-issues, which had 16 solves (out of 1127 participating teams).
