On some website I once saw a quarry and I really want to solve it. Someone shared that his cryptographer friend Raczhzzze has made his own encryption algorithm. And he wanted someone to crack the scheme without the private key. The flag will be 'flag{sha256 of the concatenated digits of the plain text}'.Cipher: 1445, 2897, 1438, 2890, 1444, 2901, 1439, 2891, 1444, 1435, 2902 Public Key: 2909. So, You will see <a href="https://assignmentman.co.uk/proofreading/">https://assignmentman.co.uk/proofreading/</a> for getting important facts about the proofreading.
