Encrypting and Decrypting a Single File or Folder with Symantec Endpoint Encryption
NOTE: Symantec Endpoint Encryption (SEE) is no longer available for download, please see information on BitLocker to meet encryption compliance on Windows computers used at CUMC.
Information on this page is for existing SEE installations only, the main SEE page will be updated with details on its use at CUMC going forward.
If your computer has SEE installed, you can use it to encrypt individual files or folders that can then be saved to an external USB key or drive, or burned on CD or DVD.
Encrypting and Selecting a Password
- In all of these instances, you will tell Symantec Endpoint Encryption what password must be used to decrypt and view the file or folder.
- Symantec Endpoint Encryption does not have to be installed on the Windows computer where the file will be opened or decrypted. Macintosh computers will not be able to open the SEE encrypted file.
- Anyone who attempts to open the encrypted information will be prompted to enter the password you select, and will not be able to view it otherwise.
- IMPORTANT: Once it has been successfully opened it will be saved as an unencrypted file on the receiving computer or drive, and should be deleted or encrypted again if necessary.
- On the computer running Symantec Endpoint Encryption, browse to the file or folder you would like to encrypt.
In the screenshot below, a file called report has been selected, however you can encrypt any type of file or folder.
- Right click on the item and select Symantec, then Encrypt to self-extracting archive from the menu that appears.
Opening and reading the Archive file requires that it be decrypted using the instructions below.
- The Symantec Endpoint Encryption Removable Storage Self-Extracting Archive window will appear. In the Archive Name field, SEE will have automatically generated a random name for with an .exe extension.
- If you don't want the actual file name to be visible by those who may see the encrypted file, you can leave it as is.
- If you'd like the file to show a more descriptive name you can type in something else, but be sure to leave the .exe extension at the end.
- In the Encrypt to field SEE displays the location on your computer where it will save the file. If desired you can change the default location by selecting items listed under the next field titled Folders/Drives:. You may need to use the scroll bar to the right of this field to view more available locations.
- Select the check box to the left of the Password option, then type in your desired strong password in both the Password and Confirm fields.
- Keep in mind that this password must be given to any desired recipient; do not use one that must be not be shared such as the password used when logging into your computer.
- Per CUMC policy, do not send a password or decryption key in the same medium as the encrypted file(s). This is insecure and can allow anyone who may accidentally or maliciously intercept the message to view the information you intended to protect. Sanctioned methods of sending a password to encrypted file attachments are by phone call or text message.
- There is an option to Use Removable Storage default password, which can be chosen in the main SEE Client screen. If you will be the only person accessing the file/folder, it is ok to select this option.
- Click the Encrypt button to encrypt the file or folder. You may see a message that encryption is in progress; if the size of the file or folder is large it may take a few moments to finish.
- When encryption is complete, the Symantec Endpoint Encryption success window will appear. Click OK.
- The encrypted file will have been created at the location specified in step 3 above. Once encrypted by SEE, it is recognized as an Archive file and will have an .exe extension. You can now copy or move it to a USB drive, CD or DVD.
Decrypting an Encrypted File or Folder
If you have received a file or folder that was encrypted using SEE it can be decrypted and opened or read by completing the following steps.
- You must know the password that was set when it was encrypted.
- Please note this cannot be done on Macintosh computers; any Windows computer can be used whether or not SEE is installed.
- Save the SEE file to the desired location on your computer, then double-click it to start decrypting.
- The Symantec Endpoint Encryption Self-Extractor Password window will appear. Type in the decryption password that was given to you and click OK.
NOTE: If you see a window prompting for the Extract to location please click here for instructions.
NOTE: SEE allows you four attempts to type in the correct password. If it is not entered correctly, you will have to wait for one minute before being able to try again.
- When the correct password is entered, the Symantec Endpoint Encryption Removable Storage Package Modifier window will appear and display the original file or folder name. Select the Extract To button near the bottom of the window.
- The Removable Storage Extractor window will appear. You can decrypt the file in the default Extract to location, or select a different location under the Folders/Drives area. Click the Extract button at the bottom of the window when you are ready.
