FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -Encryption refers to converting plain text data into unreadable code called ciphertext. It works using a key – a mathematically-generated string of text translating the data into code. Encryption helps hide information, preventing unauthorized parties from stealing it.

Detailed explanation-3: -transforming it back into the readable plain text is called decryption.

Detailed explanation-4: -An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key.

Detailed explanation-5: -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.
