Encrypting files
Files that contain confidential data need to be encrypted prior to sharing or emailing. Depending on how the file will be stored will determine how the file will need to be encrypted.
- Encrypting a file stored on a local machine drive
Right click on the file and select Properties.
Select Advanced.
Place a check in the option Encrypt contents to secure data and select OK.
Select Apply, then OK.
- Encrypting a file for cloud storage (OneDrive)
Files with confidential data that will be moved to OneDrive also need to be encrypted. Some software comes with the ability to encrypt the document, such as password protect. For information on how to use the software to encrypt a file, check out the Help section for the software.
If the software does not provide a way to encrypt the file, IT@Sam recommends using a compression tool with password protection, such as 7-Zip, to encrypt the file prior to moving the file to OneDrive. There are several compressions tools that offer password protection, but IT@Sam makes 7-Zip available in the Software Center. If you would like to use 7-Zip, please follow these directions on how to encrypt a file and open an encrypted file.
To install 7-Zip, open the Software Center and select 7-Zip. Then select Install.
Once 7-Zip is installed, locate the file in File Explorer. Right click on the file, select Add to archive… from the 7-Zip options.
In the Add to Archive dialogue, select zip in the Archive format option, enter and reenter the password, select AES-256 for the Encryption method and select OK.
The zip file will then be saved in the location of the original file and the zip file can be moved to OneDrive.
If you are not using the OneDrive Sync Client, the zip file will have to be downloaded from OneDrive online prior to opening.
To open the encrypted file, right click on the zip file and select Extract files… from the 7-Zip options.
In the Extract dialogue box, select the location the file will be extracted to, enter the Password and select OK.
A folder will then be displayed in the location specified previously.
