Crypto Cracker is a tool that can be used to crack Word Ciphers. A Word Cipher, also known as a Cryptogram or Cryptoquote, is a puzzle where one letter in the puzzle is substituted with another.  For example, the cipher:

Has the following solution:

In the above example a 'e' is replaced with a 'c'. Therefore, all e's must be replaced by a 'c'. The puzzle is solved by recognizing letter patterns in a word or words and successively substituting letters until the solution is reached. 

Type a word cipher into the Crypto Cracker text box and the Crypto Cracker will attempt to crack the cipher. The Crypto Cracker will return its best guess after 5 seconds. This limit may be extended to 10 seconds. Word Ciphers may have more than one solution. Crypto Cracker will return the first 5 solutions it can find. Optionally, 10 solutions may be displayed.

Common sources of ciphers are the newspaper and puzzle magazines. Many ciphers, such as the Cryptogram found in most newspapers, will not use a letter to represent itself. If you know this to be the case, the option "Letter Can Represent Itself" should be unchecked. Crypto Cracker will only find solutions where no letter is used to substitute itself. 

The Crypto Cracker has an extensive dictionary. Entries are weighted based on the frequency that they occur in common language usage. Single letter words that are preceded by and followed by a period are considered to be initials. Crypto Cracker makes no attempt to actually figure out initials. Instead, it substitutes the first unused letters. If 'Show All Possible Initials' is checked, the Crypto Cracker will generate answers using all permutations of unused letters.
