What type of software scrambles your data by using a multi-digit key?

Encryption software is designed specifically to protect data by converting it into a form that is unreadable to unauthorized users. This process involves using algorithms and a multi-digit key to transform the original data into an encrypted format. Only those who possess the correct key can decrypt and access the original information. This ensures confidentiality and security for sensitive data, making encryption vital for protecting personal information, financial details, and any data that must remain private.

In contrast, compression software reduces the size of files for storage efficiency and quicker transfer, firewall software provides security by controlling incoming and outgoing network traffic based on predetermined security rules, and backup software focuses on creating copies of data to prevent data loss. These software types serve distinct purposes and do not involve the scrambling of data for security as encryption software does.
