Last week I used Opus 5.5 to decipher a number of Waffen-SS Truppenschlüssel messages from 1941 that had never been broken. It was a similar approach, I used it to find, transcribe, and process over 10K images from various archives of WW2 material. Within that material was text I could use to help break day ciphers, to use as cribs, and so on. Opus didn't find a new vulnerability in these 85 year old ciphers, but it allowed me to process data at scale in languages I don't speak, and to write a dozen solvers in the time it would have taken me to write one or two by hand. Took what would have taken a research grant, three assistants and a year of time and turned it into a weekend project.
