Encrypting and Decrypting Files

This section explains how to encrypt and decrypt files using a digital certificate stored on your HID Crescendo device. Adding your digital signature to a document protects the content and authenticates you as the owner. Depending on your smart card content and your platform configuration, you can seamlessly encrypt and decrypt files.

Encrypt a File

  1. Insert your HID Crescendo contact card (chip-side up and chip first) into the smart card reader, or place your HID Crescendo contactless card on a contactless smart card reader, or plug the HID Crescendo Key into a USB port and wait for a steady or flashing Green light.
  2. Create your document.
  3. In the protection options of your document editor, select to either add your digital signature or encrypt the document.
  4. When prompted, enter the PIN protecting the certificate.

Decrypt a File or Folder

  1. Start Microsoft Explorer.
  2. Insert your HID Crescendo contact card (chip-side up and chip first) into the smart card reader, or place your HID Crescendo contactless card on a contactless smart card reader, or plug the HID Crescendo Key into a USB port and wait for a steady or flashing Green light.

  3. Open the file or the folder to decrypt.
    A window is displayed at the lower right corner of your desktop prompting you to enter your smart card PIN.

  4. Click on the displayed link in the notification area.

  5. Enter your smart card PIN and click OK.
    The file or folder is opened in clear text.
