Encryption and decryption:

Major differences between the two giants:

The algorithm of encryption uses plaintext along with a key to encrypt a piece of data to make it inaccessible by all means and directions. The decryption algorithm reverts the data back to its original form using the key that has the ability of decoding.Image result for Cloud Computing

The process of encryption is done by the person sending the information. Decryption is quite inverse of it and is done at the very end of the receiving recipient.

The former type is designated to convert the plaintext into cipher text. While on the other hand, the decryption process converts the cipher text into plaintext.

Encryption plays any important role in data security on both mobile and desktop platforms. Newsoftwares is one of the top notch names in the field of data encryption for securing important files and data

Encryption – in detail:

The term encryption is a method of converting the actual data into another form that sends the coded information out via network undetected. The sending side needs to have an algorithm of encryption along with a key to convert the data into a cipher text which is also called as enciphering.

Data in raw form is called plaintext and must be protected one way or the other. The same data after being converted called cipher text is a mean of scrambling the data as a result of encryption using a rare kind of a key.

In a straightforward term, the methods of encryption including both encryption and decryption have keys that are secret and same. Conventional means of encryption are divided into two categories/classes:

Bit level encryption and character level encryption.

Bit level encryption:

In this method, the data that needs protection is divided into bits of blocks which is further edited via encoding, decoding, and other similar processes.

Character level encryption:

Character level encryption the process of encryption is carried out at character level. It includes two types of tactics such as transpositional and substitutional.

Decryption – in detail:

The basic idea of decryption is that it inverts the process of encryption to revert the actual information back to its original form. The designated recover uses an algorithm of decryption along with a key to convert the cipher text back to the plaintext which is ultimately called as deciphering.

A scientific method used for decryption that creates actual plaintext as a result of one or more given cipher text. In short, this method is the totally inverse version of encryption.

Keys utilized for encryption/decryption may or may not be similar as it all depends upon the type of cryptosystems that were used in the making at the beginning.

Public key encryption:

This type of encryption utilizes a set of complementary keys (such as a private and public key) to encode or decode a given piece of information. The dual keys are quite similar and related as one key locks the data while the other key unlocks the same data. However, regardless of them being related, the information of a public key cannot make it possible to measure the consistent private key.

Shared key encryption:

This type of encryption utilizes only one key to encode or decode data or information. In the shared key, the recipient along with the sender must have the same key which is supposed to stay confidential at all times. The person sending the data uses a shared key to encode a message, while the person sitting at the receiving end decodes its using their authority.

Verdict:

The two types of encryption are both at an end extreme forms of each other and are inversely related to one another. But in order to ensure the survival of former type, the latter type must also exist or else it would be meaningless. According to PCMag, only the best encryption tool can keep your data safe.If you are able to put a lock on a file but cannot even access it, it would be useless.
