[Solved]Write C Program Performs Following Tasks 1 Encryption Message Rotation Cipher Given Messag Q37292580

Write a C program which performs the following tasks:

1. Encryption of a message with a rotation cipher given themessage text and rotation amount

2. Decryption of a message encrypted with a rotation ciphergiven cipher text and rotation amount

3. Encryption of a message with a substitution cipher givenmessage text and alphabet substitution

4. Decryption of a message encrypted with a substitution ciphergiven cipher text and substitutions

Inputs

– Read from stdin with scanf()

-All input data is to be encoded with the ASCII standard. ASCIIencoding defines that upper and lower case letters be stored as thefollowing 8-bit integers:

If an input byte is outside of the ranges [65, 90] and [97, 122]then it can be copied to the output without modification. If aninput byte is in the lower case range, [97, 122], then you shouldsubtract 32 from its value to make it an upper case letter prior toencryption.

Outputs

– All output should be sent to stdout.

Conditions

– For the purposes of this assignment youshould apply the following rules:

1. Do not encrypt white space, punctuation, or numerals. If aninput character is not a letter it should be copied to the outputunmodified.

2. All input data should use UPPER CASE letters only •(Advanced) If a lower case letter is found in the input it shouldbe converted to upper case before encryption

3. Code Must be contained in one .c file only (Provide a menusystem to choose what action will be executed)

4. Code Must run with GCC

5. Code Must provide comments of whats happening.
