Introduction

We are living in a world where data has got the utmost importance. Business organizations have realized that they can level up their services by making the most of the raw data and putting it to use for their benefit. But the process has a lot of technology it is into it and one of which is playfair cipher. It is a phenomenon that is used for the encryption of data. Data encryption is one of the most vital processes with the help of which privacy is maintained.

The laws of data theft are huge and hence most business organizations have a serious attitude towards the management of data. The encryption and Playfair cipher decryption of data must be done effectively to retain privacy. The symmetric encryption is one of the technique with the help of which the sender and the receiver can encrypt and decrypt the data sent with the help of a key which is public. And the Playfair cipher is closely related to this process. So stay tuned to not miss out on any single detail about the Playfair cipher rules and what is Playfair cipher.

1. What is Playfair cipher?

The Playfair cipher code is a technique of symmetry encryption. The simple description of the Playfair cipher would be it is a written code and it became the first technique was used for the encryption of data. It was first introduced in the year 1854. It has all the keys which are arranged in alphabetical letters or geometric patterns so that the decryption of Playfair cipher can be done.

The Playfair cipher is also referred to as Playfair square. It was created by Sir Charles Wheatstone. But it was named after a lot of affairs he was the one who promoted the uses of it. It was then used by the Britishers and the Australians in the world war and to retain privacy on certain messages which layer to be transferred from one place to another.

The Playfair cipher encryption method involves the creation of key tables that further arranges the letter of the alphabet into a square grid. When this key table reaches the receiver then he or she separates the text into 2 bits of 2 letters. The process of encoding the message is a transposition of each two-letter to the key table. To implement Playfair cipher encryption-decryption, one needs to understand everything about it.

This is the first method that was most prominently used during ancient times for the transfer of a message from one place to another. When the message was passed from one place to another the receivers of the message could only decrypt the data from the message if they have the access to it. 

2. Advantages of Playfair cipher

The advantage of symmetric encryption through Playfair cipher example problems is at it is a secret algorithm that can be secure and it requires a lot of effort to decrypt the message. Hence it can be quite difficult to decrypt the message. But the mathematics behind that is quite complicated which might also be difficult for the real receiver to decrypt the data.  

Another advantage of playfair cipher is that the Encrypting and decrypting the data in the Playfair cipher method does not require any computation or playfair cipher decoder. It is a manual method and it does not need any e computer for the decryption. Hence the information can safely travel from one corner to another without reaching to wrong hands when you implement playfair cipher encryption decryption in c. The c code of playfair cipher is easy to understand as well. 

3. Disadvantages of Playfair cipher

The symmetric cryptography through the Playfair cipher program technique can be easily cracked and the amount of data encryption and decryption will be less. It cannot be used for the transmission of a huge amount of data which is one of the most disadvantage factors of the technique.

There are a few other disadvantages of playfair cipher as well. The relationship between the key and the ciphertext is quite confusing and you can also explain playfair cipher with example which can prove this. Above all it o has a property of. All the statistical structure of the plain text over the cipher text gets driven away. 

4. Playfair cipher’s relevance

The application of Playfair Cipher encryption and decryption was days back during World war time and with the passage of time and the advancement of technology, the technology has failed to be relevant. It can be easily decoded and the data can easily go to the wrong hands. Hence, the outdated technique cannot be recommended for business organization to opt to. Above all, it is a manual or a labor-centric technique which requires no playfair cipher calculator for the decoding. There is a playfair cipher program in C and C . The playfair cipher python code can also be opted as it is a simple coding.

5. Examples of Playfair cipher

We can understand the play fair cipher in a little way by considering a playfair cipher example. Here we present an example to understand the intricacies and the method of playfair cipher algorithm. For instance, the message is “HELLO WORLD”. The words will be split into bits of two letters which would make HE & LL. The receiver good keep the edge on the top left corner and would keep the E in the bottom right corner of the key table.

And with the help of the mirror technique, the text can be effectively and coded without the use of any equipment or without following any infrastructure, it’s just that one it’s to use the printed text on a paper. Hence this play fair cipher is one of the most advanced and ancient ways of encryption for the modern computing of data.

Final Words

We have tried our best to present all about Playfair cipher its working its example and everything related to it in a manner which can be simple and understandable for the readers. We have tried to explain the intricacies of the method and have also enlightened the readers about the advantages and disadvantages of playfair cipher.

Playfair cipher is one of the most ancient methods and understanding it is the basic foundation of machine learning and data encryption. Like every other technique, this also has its fair share of pros and cons, which was thoroughly discussed above. Here is hoping that we could adequately provide information about Playfair cipher and everything related to it.
