<h1>Cryptography and MMCTF workshop</h1>
<p><strong>Date</strong>: 2025-02-19</p>
<p><strong>Difficulty</strong>: Intermediate</p>
<p><strong>Delivered By</strong>: SUCSS committee</p>
<h2>Overview</h2>
<p>Dave has created yet another website, so this week we have some more crypto challenges.
We will also give a short presentation on making your own challenges for the MMCTF later this year. Making your own CTF challenges is a great thing to talk about during interviews and put on your CV, not to mention it's a fun experience. If you have any ideas for challenges, definitely give it a go! We'll be available to help with any ideas you may have and give tips on creating challenges.</p>
<p>If you do create a challenge, you can submit it <a href="https://forms.office.com/Pages/ResponsePage.aspx?id=-XhTSvQpPk2-iWadA62p2Iil0HOzRRlPh6mtsEOJGulUOVVHMEQzODBOVUtQOVNEVTdQTVdSWDc3Uy4u">here</a> and it will be featured in the MMCTF, where everyone will have a chance to try it (and you can try everyone else's challenges).</p>
