Explanation / Answer

Hi ,

As per the problem statement , Please find the solution below:

Note: Given problem statement , not mentioned the whether need to consider the whitespace or not, as standard ignoring the whitespace and providing the solution below:

Please find the Solution below:

Provided String : Once we accept our limits, we go beyond them.

Key : MATH

Encrypted String :  anvl ie tjoeia auk sumbae, wx na bxfanw atef.

Procedure :

Introduction :

1) Vigenere cipher is of type polyalphabetical cipher.

2) In this kind of encryption, and unlike monoalphabetical ciphers , one letter can be ciphered in different ways depending on its position in the text.

3) Vigenere cipher introduced the concept of key to encrypt the data.

4) This key brings a huge evolution into ciphers, letters frequency analysis

Process:

1) In this Vigenere encryption process, We use a table, which is easy to remember in its original form.

2) This table is bi-dimensional and have alphabet letters in X and Y axis (from A to Z).

3) On X axis, the letters are the one from the plaintext that you want to encrypt.

4) On the Y axis, the letters are the one from the key you want to use to encrypt the data.

5) To encrypt, you start by repeating the key so that every letter from the plaintext has a corresponding key letter.

6) That means that for a plaintext which has 7 characters, and a key that only have 3, you'll have to repeat 2 times the key, then just add the the first letter of the key.

In our example :

Once we accept our limits, we go beyond them.

MATH MA THMATH MAT HMATHM, AT HM ATHMAT HMAT.

Using both string and key x-axis and y-axis , get the encrypted key as follows,

anvl ie tjoeia auk sumbae, wx na bxfanw atef.

Explanation : In this process take ‘O’ as first letter from string and ‘M’ as first letter from key , check the bi- dimensional table and get the cipher letter as ‘A’.

In the need to follow for remaining to achieve the entire text encryption.

Thanks
