This task had an encrypted RAR archive with a single 7-byte file stored in it. Similar tasks happened in the past, forinstance: [here](https://github.com/p4-team/ctf/tree/master/2016-06-04-backdoor-ctf/crypto_crc) or[there](https://github.com/p4-team/ctf/blob/820f3215e3c45f18e3073d55c7c3e745d37fb878/2016-08-21-bioterra-ctf/zip/README.md).We simply modified code used in these tasks, and it turned out one of the contents found using `a-z0-9` alphabet wasthe correct one.
