Here are the most common examples of encryption. There are several types of encryption, each developed with different needs and security needs in mind. A private key, which is not shared, decrypts the data. A public key, which is shared among users, encrypts the data.

Asymmetric encryption uses two keys for encryption and decryption.

Symmetric encryption uses a single password to encrypt and decrypt data.

There are two types of encryption systems: symmetric encryption and asymmetric encryption. Encryption keys are created with algorithms. Symmetric and asymmetric encryption: What’s the difference?Īn encryption key is a series of numbers used to encrypt and decrypt data. To unlock the message, both the sender and the recipient have to use a “secret” encryption key - a collection of algorithms that scramble and unscramble data back to a readable format. When the intended recipient accesses the message, the information is translated back to its original form.

How does encryption work?Įncryption is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format - called “cipher text.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the internet.

It’s nearly impossible to do business of any kind without your personal data ending up in an organization’s networked computer system, which is why it’s important to know how to help keep that data private.Įncryption plays an essential role. Vast amounts of personal information are managed online and stored in the cloud or on servers with an ongoing connection to the web. It helps provide data security for sensitive information.

Encryption is the process that scrambles readable text so it can only be read by the person who has the secret code, or decryption key.
