Signing and encryption with a digital seal (crypto-stick)

To use a digital seal and encryption certificate issued on a crypto-stick with DigiDoc4, you will need:

  • SafeNet Authentication Client software must be installed on your computer along with the ID-software.
  • SafeNet Authentication Client software must be used to change or unlock the PIN code.
  • Note: If you have a macOS, you will need to install the DigiDoc4 Client application in .zip format from GitHub.

Signing with a digital seal

The process of signing with a digital seal is very similar to signing with the ID-card. The only difference is that a SafeNet Authentication Client dialogue window will come up when the PIN code is entered.

  1. Connect the crypto-stick to your computer.
  2. Open DigiDoc4 and make sure that the digital seal data are pulled correctly from the crypto-stick.
  3. Choose the document for signing.
  4. Press the “Sign with e-Seal” button.

  6. This will create a digitally sealed document, to which signatures given by ID-card can be added.

Decrypting a file encrypted by digital seal

Opening encrypted documents using a crypto-stick and digital seal certificates works the same way as with the ID-card.

  1. Connect the crypto-stick to your computer.
  2. Double-click on the name of the encrypted document (.cdoc file).
  3. This will bring up DigiDoc4 – if it does not open, open it manually yourself and select “CRYPTO“.
  4. Once the crypto-stick has been inserted correctly, DigiDoc4 will read the encryption certificate data off of it.
  5. Press the DECRYPT button in the lower right corner of the screen.
  6. This will bring up the “SafeNet Authentication Client” PIN dialogue window.
  7. Enter the crypto-stick’s PIN code and press OK.
  8. The document is now decrypted and ready to be opened!
