What is Encryption?

Or Encryption meaning? It is a process by which readable data is converted into encrypted incomprehensible data that can only be understood or read after decoding. Encryption is an essential unit for maintaining data security; To ensure that it is not stolen or read.

One of the formulas used for encryption is the term algorithm and it consists of three basic units: encryption, decryption, and key, and this, in turn, is divided into two parts: a public key and a private key. The key is a secret code and is the surrogate that was put in during the encryption process.

Types of Encryption

There are two techniques by which encryption is used and each of the techniques depends on the type or nature of the key, namely:

Symmetric Encryption

It is also known as traditional encryption, in which a single key is used for encryption and decryption, and for this it is important to adopt a secure method for the key to be transmitted between the sender and recipient, where the person who owns the key can do the decryption and read the content of the files.

Asymmetric Encryption

It is also known as public-key encryption, and this encryption depends on the principle of a key pair, that is, the user uses two different keys while performing the encryption (public key) and decryption operations (private key).
