Substitution ciphers are those types where individual characters of the plaintext are replaced by another character and arranged in the same order. For a description of the ciphers go to the Substitution (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 cipher text 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. Notes: 1. Monoalphabetic Substitution also known as Aristocrat, Patristocrat or Simple Substitution |
