Encryption and Decryption Encryption is the process by which a readable message is converted to an unreadable form to prevent unauthorized parties from reading it. Decryption is the process of converting an encrypted message back to its original (readable) format. Encryption helps us to secure data that we send, receive, and store. It can consist text messages saved on our cell-phone, logs stored on our fitness watch, and details of banking sent by your online account. It is the way that can climb readable words so that the individual who has the secret access code, or decryption key can easily read it.

Encryption and decryption are the two essential functionalities of cryptography, the science of protecting data at the time of communication. Learn …Playfair decryption requires a grid, which can be generated by a key word. Split the text into pairs of letters ( bigrams) and apply the following rules according to the letters positions in the grid: — if the 2 letters are on the same row, replace them by the ones on their left (loop to the right if the edge of the grid is reached),For encryption and decryption processes, some algorithms employ a unique key. In such operations, the unique key must be secured since the system or person who knows the key has complete authentication to decode the message for reading. This approach is known as “symmetric encryption” in the field of network encryption.Symmetric Encryption. In symmetric encryption, the sender and receiver use an identical symmetric key to encrypt and decrypt data. Here’s how it works: The sender and receiver share the same secret key.
