Decryption
Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer. This method is performed by un-encrypting the text manually or by using keys used to encrypt the original data.
Difference between Encryption and Decryption
| Parameter | Encryption | Decryption |
| What is | It is a process of converting normal data into an unreadable form. It helps you to avoid any unauthorized access to data | It is a method of converting the unreadable/coded data into its original form. |
| Process | Whenever the data is sent between two separate machines, it is encrypted automatically using a secret key. | The receiver of the data automatically allows you to convert the data from the codes into its original form. |
| Location of Conversion | The person who is sending the data to the destination. | The receiver receives the data and converts it. |
| Example | An employee is sending essential documents to his/her manager. | The manager is receiving the essential documents from his/her employee. |
| Use of Algorithm | The same algorithm with the same key is used for the encryption-decryption process. | The only single algorithm is used for encryption and decryption with a pair of keys where each use for encryption and decryption. |
| Major function | Transforming humanly understandable messages into an incomprehensible and obscure form that cannot be interpreted. | It is a conversion of an obscure message into an understandable form which is easy to understand by a human. |
