Three steps
- Save the file. If it arrived by e-mail, download the attachment first.
- Drop it onto the page. Open asiceviewer.com and drag the file into the box, or tap the box and choose it.
- Read. The first document opens automatically.
That is all. On an ordinary connection the page is ready in about a second, and the container is unpacked on your own device.
What to check once it is open
- Is it the document you expected? Read the title and the first page.
- Who signed? Each signer has a card with name and signing time. If you expected two signatures and see one, the other party has not signed yet.
- Does the integrity line say OK? That means the files match the digests in the signatures.
- Are there attachments? A container can hold several files. Look at the whole list, not only the first one.
If it does not open
| Symptom | Likely cause | Fix |
|---|---|---|
| "The file could not be opened" | Download was interrupted | Download the attachment again |
| Only a hex view appears | The file is not a container | Check the extension and the sender |
The file ends in .cdoc | It is encrypted, not signed | Decrypt it in DigiDoc4 with your ID-card |
The file ends in .zip | A mail server renamed it | Drop it in anyway; the content is recognised |
Need more than a quick look?
For an official statement on validity, open the same file in DigiDoc4. For reading on a phone without a connection, the ASiC-E Viewer app keeps working offline. The longer walkthrough is in how to open an ASiC-E file.
Frequently asked questions
Do I need an ID-card to open an ASiC-E file?
No. An ID-card, Mobile-ID or Smart-ID is only needed to create a signature. Reading a signed file needs none of them.
Can I open several files at once?
Yes. Select or drop several files and they appear in one list, each with its own preview.
