>>11534403You don’t want a cryptographer, since they’re making something computationally expensive enough that it *cant* be broken without ridiculous amounts of time (ie, older than the age of the known universe on current hardware). Instead, you want something that can be broken by basic cryptanalysis related to things in your ARG. Look up resources affine shift ciphers (you might have to get your hands dirty with a little modular arithmetic) and frequency tables to get a good idea of something that’s fun to break.
