Transposition ciphers are those where the original characters of the plaintext are rearranged according to a system or key to form the ciphertext. For a description of the ciphers go to the Transposition (Create) menu pages on this site. The colored outline around a box indicates if the option is required or not.
Select a language Select from the drop down menu the plaintext language. This loads the appropriate language data. Default is English Use accented characters Enables the use of accented, or diacritic, characters in plaintext. Only used in the Monoalphabetic Substitution solver and with German, Spanish, Norwegian, Swedish and Danish languages. Number of threads to use Select the number of threads or cores/processors the program should use and this may help to find a solution quicker. The options available depend on the number of cores on your system. The number of threads available for CryptoPrograms is less than the number available to prevent a user accidentally slowing their machine too much. The default is 1. Enter ciphertext to be deciphered Field for the ciphertext. Invalid characters for a particular cipher type will be ignored. 'Solve Cipher' button Starts the search for a solution. 'Stop Solving' button Stops the search for a solution. Enter maximum number of best solutions to display Enter the number of best matches to display, up to a maximum of 100. Default is 10. Best solution The solution is in the form: SolutionNo. Score - Key: Solution Also displayed is the time taken to find the best match so far and the total time taken. Scores for the plaintexts are calculated from the frequency of tetragraphs in the selected language. Note: 1. Columnar Transposition includes Complete and Incomplete Columnar Transposition |
