FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -Data encryption converts data from a readable, plaintext format into an unreadable, encoded format: ciphertext. Users and processes can only read and process encrypted data after it is decrypted. The decryption key is secret, so it must be protected against unauthorized access.

Detailed explanation-3: -Encryption and data transfer You can encrypt data prior to transmission over an insecure channel and ensure it is still protected. However, a secure channel provides assurance that the content cannot be understood if it is intercepted.

Detailed explanation-4: -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-5: -In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.
