How did they use encryption in ancient times?
I cannot recommend this book enough: https://en.wikipedia.org/wiki/The_Code_Book and your local library should have it. It’s an entertaining read.

Damn, 7th century BC, that’s amazing.
Well the Caesar Cipher is named after you-know-who, who used it. And the subsequent Vigènere Cipher has been in use since medieval times.
I wonder how it worked for them given how simple this cipher is and that messages could take months to deliver.
Probably well enough, your basic footsoldier may not have been literate, and few were probably familiar enough with ciphers in general to know or be able to recognize the technique used.
I mean soldiers were not the ones who read messages from the generals encrypted or not, they just delivered them. The messages were also sealed so if the soldiers decided to break the seal they would probably deliver it to someone literate. So I wonder if there was an instance where Caesar or Augustus messages were intercepted, and how it turned out.
