Encryption

What is encryption?

Encryption is a data security method where data is scrambled or transformed via specific encryption algorithms. Once encrypted, data can only be decoded by specific parties with an encryption key. Encryption is a key strategy to protect data integrity, even when confidential data is exchanged across devices. It is also required for certain compliance regulations around data security.  

Example: We use encryption software to handle customers’ tax documents so their sensitive data is protected, then give them a private key to log in and modify their documents at any time. 

There are two main categories of data encryption: symmetric and asymmetric encryption. In symmetric key encryption, also referred to as shared key or same key encryption, the encryption and decryption key are one and the same. In asymmetric encryption, also called public key cryptography, a separate cryptographic key is used for encryption and decryption.
