@mimas2AC you are welcome. since the used book market collapsed into a monopoly a few years ago, i mostly quit buying and moved to use the inter-library loan system. it is not easy to find an entry point (a public accessible library which participates), but once you are in you have access to *everything*. usually university libraries and a few state-owned ones participate.

Exciting encryption techniques – any ideas? I’m looking for them for a school workshop with young people. Important would be a historical context, pictures / photos / videos or possibly replicas, for an easy introduction to the history of encryption. I’m interested in any tip. Thanx
