Encryption is the process of securing digital data using mathematical techniques with the help of a key used to encrypt and decrypt the data. It basically converts plaintext into Ciphertext. Encryption protects private information and sensitive data between the client and the server.
Full Answer
What is the concept of encryption?
Encryption is the process of transforming data into an unintelligible form in such a way that the original data either cannot be obtained or can be obtained only by using a decryption process. Data that is encrypted is referred to as ciphertext . Data that is not encrypted is referred to as plaintext .
What is meant by encryption Class 7?
Encryption is the process of converting simple data into a coded one. In technical terms, encryption is a method of converting plaintext into ciphertext so that only authorized users can understand it.
What is encryption for beginners?
Encryption is the process of protecting data by changing it from a readable form to an unreadable form. It uses complex algorithms to “scramble” and therefore protect data – as it's unreadable and can't be accessed.
What is data encryption how is it useful to ensure security of data?
Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext.
What is encryption class 9?
Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext). Decryption is the process of converting ciphertext back to plaintext.
What is meant by encryption Class 11?
Data encryption involves converting data into secret codes to protect the data from being misused under online business transactions.
What is the purpose of encryption?
The purpose of encryption is confidentiality—concealing the content of the message by translating it into a code. The purpose of digital signatures is integrity and authenticity—verifying the sender of a message and indicating that the content has not been changed.

How does encryption work?
Encryption begins from the simple unencrypted information, the plaintext. It is the data that is readable in its original form. To make it secure, one can apply certain encryption algorithms on the data. Using the algorithm and the corresponding encryption key, the plaintext data transforms into ciphertext.
Why is encryption important?
Encryption is necessary to prevent any perpetrator to exploit your data. Whether it is your banking information, or your personal data such as pictures, videos, and audio recordings, all the stuff should stay private to you only. When this information is encrypted, no one can use it against you.

Is encryption evil?
Maybe you're guessing correctly that I formulated the question like this on purpose.
What Is Encryption?
Encoding is the process of converting something in the physical world into a representation that can be stored or shared. Just as a photograph encodes what is seen, letters and words encode ideas and what is heard into a format that can be stored or shared. The goal of encoding is to deliver these ideas to their intended recipients. A person who does not understand the language, or does not know how to read it, will be unable to de-code the information.
How does encryption work?
Most modern encryption uses an algorithm to scrabble or encode a message by substituting the contents with a key that is generated based on a secret key or password. Modern encryption is classified as symmetric (same key for encryption and decryption) or asymmetric (two-part key; one part for encryption and one part for decryption). Even though you do not see it, most of the transactions, messages and data you send through the internet is automatically encrypted to assure privacy and security.
What is asymmetric encryption?
Symmetric encryption allows the use of the same key (a single key) to encrypt and to decrypt the data/message; asymmetric encryption allows the use of a split (two-part) key to encrypt and to decrypt the data/message. Using asymmetric encryption algorithms, the owner of the key gives out a 'public' key that may be used by anyone to encrypt a message; the second half of the key (private key) is only know to the owner of the key and is used by asymmetric encryption algorithms to decrypt the message. Using two-part (public and private) keys provides a greater degree of flexibility while maintain a high degree of security, since anyone may use the public key and only owner of the private key may read the message.
What is the art of hiding information to make it unreadable without special knowledge or a key?
Encryption is based on cryptography. Cryptography is the art of hiding information to make it unreadable without special knowledge or a key. The earliest recorded examples include the use of non-standard hieroglyphs as a substitute for the hidden information, and the use of personal identification marks such as seals, emblems, or logos for authentication. The receiver of the sealed item would have a copy of the true mark to use to authenticate the one presented (these are the precursors of signature verification).
Why is encryption important?
Encryption allows a person to hide the meaning of information or messages in such a way that only those who know the secret method may read them. For a very long time, people have had many different reasons for wanting to hide information from others.

What Encryption Algorithm Means
- Unlike primitive ciphers, modern encryption isn’t so simple. Rather, it is a dedicated algorithm that runs on the specified information to convert it from plaintext to ciphertext. This ciphertext cannot be deciphered by merely reversing a substitution cipher technique. Instead, the entire process of the algorithm needs to work in a reverse manner for smooth decryption to plaintext. Together, b…
