AES Encryption and Decryption with Advantages
What is Encryption?
Encryption is the process of converting information or message or data or file or image into a special format or secret code or unreadable format (ie hiding the actual information's meaning), so that only authorized persons can read and access it.
To unlock the message, both the sender and the recipient have to use a secret key or password.
This helps protect the confidentiality of digital data either stored on cloud servers or computer systems or mobile phones or transmitted over network like the internet.
Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext.
Encryption can help protect data you send, receive, and store, using a device. That can include text messages stored on your smartphone, running logs saved on your fitness watch, and banking information sent through your online account.
What is Decryption?
The process of converting encrypted information or message or data or file or image into a readable format or to it's original format is called decryption.
The science of encrypting and decrypting of information or data or message is called cryptography.
Currently, encryption is one of the most popular and effective data security methods used by most of the organisations around the world.
Advantages of encryption
1. Protects confidential data such as passwords and login id.
2. Provides confidentiality of private information.
3. Helps you to ensure that the document or file has not been altered.
4. Helpful for network communication and where a hacker can easily access unencrypted data.
5. It is an essential method as it helps you to securely protect data that you don't want anyone else to have access..
Difference between Encryption and Decryption
Encryption is a process of converting normal data into an unreadable form whereas Decryption is a method of converting the unreadable/coded data into its original form.
Encryption is done by the person who is sending the data to the destination, but the decryption is done at the person who is receiving the data.
The same algorithm with the same key is used for both the encryption-decryption processes.
Encryption Types:
There are several types of encryption algorithms, each developed with different needs and security needs in mind. They are divided into two types of encryption systems:
Symmetric Encryption and
Asymmetric Encryption also known as public-key encryption.
