You are right about that, a public key info would be something like: "4kpA P5S 1LUAxPThou GdIO/J3A a G ea 3k GR Ir12gTJ Py8 .Q29u Z3JhdHMgZm 9yIHVzaW 5nIGVua W dtYQ. e0e a57cdd4c0 f509193 d6ad180e ab2 27". Even though it looks like text, it can MITMed, I'll change the readme, thanks!
It can also encrypt files before you send them. The output message is formatted to go unnoticed as regular text: no long words, no special characters, spaces don't matter. It works with unicode and any language
