Here are the three types of encryptions in Data protection…



Data encryption is the process of locking messages or data being sent.When this method is used, the message will not be understood if it is been hijacked by the third party.



In my previous article, I have talked about some of the encryptions terms that you need to know when you are trying to protect your data.



Also, you need to use encryption so as to guarantee confidentiality and integrity of information.



In this article, I want to examine the three types of encryption that we have. Follow me as we do this together now.





symmetric encryption

Symmetric Encryption can be seen which is also known as the secret key, shared key uses the same key for encryption and decryption.


The key is not open to general public. That means only recipients can read sent messages. 


asymmetric encryption

Also, asymmetric encryption is also known as public key encryption. It is the use of different keys for encryption and decryption.


 asymmetric encryption is also known as public and private keys.


Under it, the key used to lock data is different from the one used in opening data.


This provides data security for sent messages. 

hash function in data protection 

This encryption method uses no key for encryption and decryption. Different keys are used to send and receive data. This can open data to hackers’ attack because of the no key method adopted. This is not too good when you need to protect your data.
