<p>you know you did something right when you can deliver shit within a day or two or just can say &quot;yeah I did see this coming and here it is ready. take it.&quot; </p><p>handful of quality tools and then you just write a little piece of new glue :)</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> i can&#39;t even read this right knowing the answer that&#39;s amazingly confusing</p>

<p>after that i considered brute-forcing it using a Kintex UltraScale FPGA that i had around (and i calculated that with the alphabet limited to 0-9 i could do it) but stopped because it felt unlikely that the intended solution to a &quot;medium&quot; crackme with &quot;Level 1&quot; in the title would involve $6000 worth of specialized hardware</p><p>this wouldn&#39;t have worked anyway because the function implements a bijection, and also because i misunderstood what the alphabet is and it wasn&#39;t 0-9</p>

<p>probably the single most &quot;i am about to give up&quot; moment was me concluding that i need to do a first preimage attack on a cryptographic function with nontrivial diffusion properties (flipping one bit anywhere changes basically the entire 16 byte output), i went to study and found out that basically no serious hash function has ever had a practical first preimage attack executed on it</p>
