Encryption Vs Decryption Full Explanation

 What is Encryption?

Encryption is the process of a transforming information or data into a unique code, so that only authorized parties or admin can read it. To be encrypted, information must be put into an unreadable format before being sent to a receiver over a public channel.
Encryption is often used when credit card numbers are transmitted between customers and merchants. When you buy something online, your credit card number and other sensitive information is encrypted before it travels through the internet. It remains encrypted as it travels to the credit card processing center and remains encrypted as they process your charge for the purchase.

What is Decryption?

Decryption is the process of a transforming ciphertext back to in its original form.

Decryption can take two forms - symmetric and asymmetric. Symmetric decryption uses a lock and key, which are the same for both parties, but asymmetric decryption relies on two different keys where one is private and one is public.

What is Encryption used for?

Encryption is the process of a encoding information so that it cannot or anybody be read by anyone who does not have a digital key to decode or decrypt it.

Encryption is used in order to ensure that the information is secure from people who want to steal or misuse that data. This process can be applied on both when data is being transmitted or transformed and when it is stored.

This method of encryption can also be used on websites, where the information on the site has been encrypted in order to prevent people from stealing private customer data.

Some types of encryption are stronger than others, so there are some pieces of information which are more difficult to steal or misuse than others.

Can Encrypted data be Hacked?

It is possible to hack encrypted data, but one would need to know the password to decrypt it. However, with time and enough computing power, it is theoretically possible to break into the system.

Encrypted data can be hacked, but only if you have the password. There is possibility that with enough time and computing power one could break it.

Where is Decryption used?

Decryption is a technique used to decrypt messages in different formats.

The two main ways that decryption is used are cryptography and cryptanalysis. Cryptography uses the technique of encryption to encode data so it can only be accessed by those who have the appropriate key or passcode. Cryptanalysis is a more complex process whereby a coded message is analyzed in order to find its meaning or decipher its code.
