WebJun 17, 2024 · If the ciphertext is written in letters, and their frequencies more or less match those of plain English text (the nonsense phrase ETAOIN SHRDLU is handy to remember for this), you're probably dealing with a transposition cipher. (If the most frequent letters don't quite match, but still look plausible for natural text — mostly vowels and a ... WebDec 14, 2024 · The end of ciphertext can be dealt with by embedding the ciphertext length at the start of ciphertext. That can work if the file is correctly prepared, e.g. by a correctly written program; or by manually concatenating a header file, the ciphertext, and the footer file using bash on a Unix system; or using copy /b of cmd.exe on Windows.
