| I included the following block of text, disguised to resemble a PGP sig, at | |
| the end of my goodbye work email. It also included information about which | |
| internal chat room to post the solution in. The first engineer to reply won | |
| the recognition of our coworkers. Can you come up with the answer? | |

It was fun, easy at some parts and tricky in others! Solved it in less than 15 minutes, took me some time to research Michigan driving licence encoding / decoding. I only used online tools, that was really nice too! Also after solving I couldn't get the correct SHA1, it seems that the last number of the epoch has changed you left 😝
