Build C++ program that can encrypt and decrypt for Playfair Cipher
$30-250 SGD
Paid on delivery
Requirement: (MUST KNOW PLAYFAIR CIPHER)
1. Name of program: [login to view URL]
2. Use command syntax:
playfair -e key <[login to view URL]> <[login to view URL]>
playfair -d key <[login to view URL]> <[login to view URL]>
where -e option is encryption and -d option is decryption
3. Program must cope with special inputs (e.g. replacing 'i' with 'j') during encryption and decryption
4. Program must be able to remove additional characters during decryption when a user inserts those additional characters.
5. Generate random keyfile [login to view URL]
6. Generate ciphertext file [login to view URL] obtained by encryption [login to view URL] under the key in [login to view URL]
7. Decrypt Ctext-3 (assuming you do not know the key) and put the explanation in Microsoft word. To test it out, test it with playfair -d [login to view URL] [login to view URL] [login to view URL] where the [login to view URL] is empty and program should do automatic decryption. Verify that [login to view URL] file is identical with [login to view URL] by executing diff [login to view URL] [login to view URL] in Unix/Linux
8. Put the statistical properties of [login to view URL] and put it in the same Microsoft word.
9. All input is lower case without punctuation
10. Playfair Cipher: 5x5 key matrix (J is omitted) -- key
