The conversion of a text or data into encrypted information, called ciphertext, using a predetermined algorithm or code so that those who know the algorithm or code can decrypt the ciphertext to recover the original data is called encryption. Modern enterprises rely heavily on encryption technology for communications and data storage for reasons including the following.
- Compliance
- Data protection
- Cheaper to build
- Back up data in motion
- Backup authentication
- Arouse the confidence of customers
- Remote work support
