Open and sign .asice and .bdoc files in the browser

Received an .asice or .bdoc file and have no DigiDoc4 on your computer? Add it to 1DOX: see what is inside, who has signed, and add your own signature.

Legally equal to a handwritten signature in every EU country (eIDAS QES).

A container you can open without DigiDoc4.

What are ASiC-E and BDOC?

ASiC-E (.asice) is the European standard digital signature container: one or more documents packed into one file together with their signatures. BDOC (.bdoc) is its earlier Estonian name — essentially the same format.

A container does not open like an ordinary document, because the signatures and files travel in one package.

What 1DOX does with a container

1DOX lists the files inside so you can view and download them. Each signature shows the signer's name, the signing time and the validation result.

You can add your own signature or invite others — the new signature is added next to the existing ones.

Make your own container

Put several files in one ASiC-E container and send it for signing. Files can be added and removed until the first signature locks it.

Frequently asked questions

Are .bdoc and .asice the same?
Practically yes. Both are ASiC-E containers; .bdoc is the extension Estonia used earlier.
Does opening a container cost anything?
No. Adding and viewing a container is free. You only pay for your own signature (€0.36).
Can I turn an .asice file into a PDF?
The files inside can be downloaded separately. If you want a signed PDF, start a new signing in PDF format.
