4. Benefits of Cryptography

Ease of Use

For simple encryption, such as encrypting the files on your hard drive, a symmetric system should suit your needs. Symmetric encryption only requires you to maintain and remember a single key and only requires a single decryption step to return your data to a readable format. If you have a secure method of communicating a symmetric key to multiple users, you can also use a symmetric encryption system to share data across a network. The same key will allow any authorized user access to the hidden content.
