The project is python 2.7.12 implementation of shift cipher cracking using english letter frequecy method.

The sample results is given as below:

Enter the cipher text: ItlxhfsmjqugtymjqijwqdujtuqjfsihmnqiwjsbnymymjnwifnqdqnkjGjhfzxjitlxfwjxtfhynajymjdhfsgjlwjfygziinjxktwjcjwhnxjYmjwjfwjrfsdinkkjwjsyitlxkwtrymjwjfqqdgnlytymjxrfqtsjxDtzhfsywfnsdtzwitldtzwxjqktwxjsinyytxhmttqnstwijwytrfpjnytgjinjsy

Note: The program can be worked with any size of input but the size should be more than 30 letters for good results. Only enlish letter (A-Z or a-z) can be deciphered and blank space will be appeared with letter 'n' in recovered plain text
