Here’s one more Vigenere running key cipher. It took me a long time to solve this using the word/phrase search program and the combination interactive solver and hill-climber. I kept going back and forth between all 3 of these. The initial search turned up a pretty good phrase, which I’ll include in caesar-shifted form. But I still had to do a lot more searches with various options. The searches did turn up the short initial word, and the longer word at position 23 (relative to starting at 0). With the position 23 word in place, the hill-climber got the exact solution. I’ll include a screenshot of the word/phrase search options.
