Choose a substitution cipher and call it CIPHER. Write a C (or any common language) program that implements your CIPHER. Write a C (or any common language) program CRACKER that uses the letter frequency count method to decrypt the ciphertext generated by your CIPHER. CRACKER should take as input a ciphertext ctext generated by CIPHER and return a "decrypted" form of ctext.
The decryption is not expected to be perfect! You may hard code your input plaintext or read it from a file.
Your CIPHER and CRACKER should not remove blanks, capitalizations, and punctuation marks! You do not have to encrypt digits.
Hi there, I went through the requirements and I would like to do this project if given the opportunity. Let me know if you are interested. Thanks.
