Encryption is the process of protecting digital data by converting it into a code to prevent it from attacks or unauthorized access. Encryption is used by individuals as well as companies to protect confidential and sensitive information from being hacked. Encryption is also used by the government and military. Whenever you’re using your credit card to purchase a product or make transactions, encryption protects the information being inputted during the process. Even when you browse the web, shop online or go through mail messages on your device, encryption is out in place to keep the information intact and secure. Without encryption, sensitive information can be stolen, attacked or hacked.

As encryption is highly beneficial to humans, it is still not used for some reason. Here are some of the reasons;
Most people forget their passwords
Encryption demands the use of passwords to encrypt and decrypt information. People often, for some reason, tend to forget the password they used. This is one of the reasons why most people feel less urged to recover encrypted information again. Forgetting your passwords may never allow you to recover encrypted information again. However, you can create an easy-to-remember password when you want to encrypt data.
Encryption may require permissions or cooperation
In cases where an encrypted file is to be accessed among two or more people, it can be of a disadvantage as some of them can find it tedious to use encryption.
Encrypting Information can bring about suspicion
When you begin to encrypt information, it becomes suspectable to online threats and attacks as hackers will begin to find ways to get unauthorized access to it. I hope you know that public information doesn’t get hacked, only private and encrypted ones do.
Why you should use encryption
- Encryption prevents service providers from accessing and mistakenly exposing your data
- Encryption safeguards you from breaches.
- When you encrypt your information, you’ll have a sense of confidence that your information is safe and secure.
- Encryption helps you to maintain integrity and privacy.
- Encryption helps to meet up with compliances and regulations.
Types of Encryption
This is a type of encryption whereby just a key, which is also known as a secret key, is used to encrypt and decrypt electronic information. Symmetric encryption is done in a way that data is converted to a form that is not concise to anyone who is not with the secret key to decrypt it.
Symmetric encryption is used in card transactions, validation messages or even the generation of random numbers and many more. There are two types of symmetry encryption algorithms namely: Block algorithm and Stream algorithm. Although symmetry encryption’s operation and maintenance can be tedious but it is a reliable way of securing information.
This is also referred to as public-key encryption, it is a process whereby the encrypter uses two related keys, which are a public key and a private key, to encrypt and decrypt data. The public key is used to encrypt data while the private key is used to decrypt data.
In asymmetric encryption, the public key is accessible to everyone but immediately it becomes encrypted, such data can only be opened by the relative private key. Asymmetric encryption is used to verify the authenticity and integrity of data.
