Encryption is the process of converting data into a scrambled format, called ciphertext. Encryption is used to protect data from unauthorized access. The process of converting ciphertext back into its original form, called plaintext, is called decryption.

There are two main types of encryption: symmetric encryption and asymmetric encryption.

• Symmetric encryption uses the same key to encrypt and decrypt data. This type of encryption is faster than asymmetric encryption, but it is also less secure.
• Asymmetric encryption uses two keys: a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt data. This type of encryption is more secure than symmetric encryption, but it is also slower.

Encryption is used in a variety of applications, including:

• Secure communication: Encryption is used to protect data that is being transmitted over a network, such as email and online banking.
• Data storage: Encryption is used to protect data that is stored on a computer or other device, such as hard drives and USB drives.
• Mobile devices: Encryption is used to protect data on mobile devices, such as smartphones and tablets.
• Cloud computing: Encryption is used to protect data that is stored in the cloud.

Encryption is an important tool for protecting data from unauthorized access. By using encryption, you can help to keep your data safe from hackers and other criminals.

Data Encryption is a process of converting data or code in such a way that in can be accessed using Secret Key. this process is called incription/Decription.

Encryption is the conversion of electronic data into another form, called ciphertext, which cannot be easily understood by anyone except authorized parties.

Encrypted data is inform of plan text and commonly referred to as cipher text as a unencrypted data. The process results in ciphertext, which only can be viewed in its original form if it is decrypted with the correct key. 

Types of Encryption:- 

(1) Symmetric Encryption

(2) Asymmetric Encryption
