Using 7-Zip to Encrypt Files/Folders

For Mac OS instructions, please visit:

  • For on campus use, 7-Zip should already be installed
  • For home use, please see and select the Download link

  •  Once the software is installed, please follow these steps to encrypt a file or folder

1) Right click on the file / folder to be encrypted

2) Select 7-Zip then Add to archive...


3) In the Add to Archive window change the name of the archive you wish to create


4) Ensure that the Archive format is left as 7z

5) Change the Encryption Method to AES-256


6) Enter a Password

  • For best practices use a strong password with at least 12 characters containing upper and lowercase letters, and a minimum of one number


7) Select OK to create the encrypted archive file. The new archive file will be located in the same folder as the original

8) You will need to inform the recipient that they will also need 7-Zip installed in order to extract files/folders

9) To extract right click after downloading the zipped file and select 7-Zip and then Open Archive

10) Once opened, you will need to select Extract


11) Click OK and then you will be prompted for the password


Best security practices recommend that you do not email the password with the Zip file as it could be intercepted in transit. It is better to call the recipient of the Zip file and convey the password over the phone.
