FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Cryptography enables you to store sensitive information or transmit it across insecure networks (like the Internet) so that it cannot be read by anyone except the intended recipient.

Detailed explanation-2: -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-3: -Symmetric ciphers, also referred to as secret key encryption, use a single key. The key is sometimes referred to as a shared secret because the sender or computing system doing the encryption must share the secret key with all entities authorized to decrypt the message.

Detailed explanation-4: -Encrypt your data One of the best ways to protect data confidentiality is encryption. Simply put, encryption is a process that uses an algorithm to turn data into an unreadable format. Only authorised people can decrypt the data and read it. To everyone else, encrypted data is intelligible.

Detailed explanation-5: -509 certificates as binary security tokens to digitally sign and encrypt messages. These certificates also provide data confidentiality and data origin authentication.
