It is the process of encoding messages or information in such a way that only authorized parties can read it. Encryption does not of itself prevent interception but denies the message content to the interceptor. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, large computational resources and skill are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
In simple words, it is the most effective way to send data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text; encrypted data have referred to as cipher text.
Why We Send Encryption Messages
It is now commonly used in protecting information within many kinds of civilian systems. If you send data from the unsecured or open wi-fi network, it may be easy to hack your data. Encryption helps us to protect your private communication, an encrypted message only open with a secret key.
