To create encrypted archives that can be opened both in Mac OSX and in Windows, we recommend an open-source application called 7-Zip for Windows users and Encrypt Files or Folders for OSX users. This software allows that encrypted archives created in OSX can be opened in Windows (and vice versa).

- Decrypting an encrypted archive in OSX
Head to 7-Zip.org, where you can download the latest version of 7-Zip for your operating system. The software is open-source, so it's free.
- Right click on the files or folders you wish to encrypt and select 7-Zip --> Add to Archive.
- Set the Archive Format to "Zip"
- Set the Encryption Method to "AES-256" \
- Enter your desired password under Encryption
- Click OK and your new encrypted zip file will be created.
- Right click on the zip file and click extract
- Enter the password you created
Managed Software Center includes a download of Encrypt Files or Folders
- Open Managed Software Center and install Encrypt Files or Folders
- Click on Encrypt Files or Folders in the doc
- In the screen that pops up, select the files or folders that you would like to encrypt
- A message will pop up with a three word password for your new encrypted archive. Click OK.
- Depending on the size of the files, it may take some time. Another pop up will appear with your password after encryption is complete.
- Click on the file you wish to decrypt and you will be prompted for your password
- Enter your password and your files or folders will appear in the same location as the encrypted archive.
Note: You can attach an encrypted archive to an email just as you would attach any other file. Remember, though, that you'll also need to relay the archive password to the recipient. Whatever you do, don't include the password in the text of a message, along with the attached encrypted archive!
