Kryptos 2020 Challenge 1

Challenge 1

A group seems intent on hacking into a government website used to collect U.S. Census data.  It is unclear whether they intend to steal data or just disrupt the entire process.  We have been monitoring an SMS-based conversation between two of the members (who also happen to be members of the Fellowship of Armchair Cryptologists), but they recently started using some sort of cipher.  We intercepted two recent text exchanges between these two individuals.  The first set of texts are in the clear, but the second set is encrypted.  We hope you can figure out what information the encrypted portion of these texts contain.  Please sent your cryptanalysis results as soon as possible!

Take the Next Step to Becoming a Wildcat.
