COMPUTER FUNDAMENTALS

Detailed explanation-1: -Encryption is the transformation of data into a form unreadable by anyone without a secret decryption key. Its purpose is to ensure privacy by keeping the information hidden from anyone for whom it is not intended, even those who can see the encrypted data.

Detailed explanation-2: -Cryptography is the process of converting between readable text, called plaintext, and an unreadable form, called ciphertext . This occurs as follows: The sender converts the plaintext message to ciphertext.

Detailed explanation-3: -Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.

Detailed explanation-4: -The encrypted message is called the ciphertext message. Digital encryption algorithms work by manipulating the digital content of a plaintext message mathematically, using an encryption algorithm and a digital key to produce a ciphertext version of the message.

Detailed explanation-5: -The term cryptography refers to methods of making data unreadable or undecipherable by anyone except the authorized recipient in the event that the message is intercepted by someone else.
