What is meant by Decryption?

Decryption is a process through which the already encrypted data or ciphertext is returned to its readable form, usually referred to as plaintext.

 A piece of data becomes unreadable if it is encrypted since it undergoes some special algorithm with a unique key. Thus, it will become undecipherable for any person who does not possess the right decryption key. 

The process of decryption, hence, involves the application of the right decryption algorithm together with the appropriate key of decryption so that the encryption is reversed and an original form is restored from the given data.

PROCESS

Sender send the data in encrypted form which is unreadable. When that unreadable text is received by the receiver, they use the decryption key and the decryption algorithm will undergo to convert that unreadable data into readable form. Without the right decryption key, it’s impossible to convert unreadable text to readable text.
