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.

Encryption is used to protect data from being stolen, changed, or compromised and works by scrambling data into a secret code that can only be unlocked with a unique digital key.

There are several data encryption approaches available to choose from. Most internet security (IS) professionals break down encryption into three distinct methods: symmetric, asymmetric, and hashing. These, in turn, are broken down into different types. We'll explore each one separately.

The IDEA cipher encrypts text with the assumption that security in IDEA is not predicated on keeping the algorithm a secret, but rather on ignorance of the secret key. International Data Encryption Algorithm (IDEA) is a form of symmetric key block cipher encryption.

Encrypt a single message In message that you are composing, click File > Properties. Click Security Settings, and then select the Encrypt message contents and attachments check box. Compose your message, and then click Send.

The two most widely used methods for data encryption are public key, also known as asymmetric encryption, and private key, or symmetric encryption. Both rely on key pairs but differ in how the sending and receiving parties share the keys and handle the encrypt/decrypt process.

For shared key cryptography to work, the sender and the recipient of a message must both have the same key, which they must keep secret from everybody else. The sender uses the shared key to encrypt a message, shown in the following figure, and then sends the ciphertext message to the recipient.
