Extracting one file
Open the container in ASiCE Viewer. Each row in the file list has a download icon on the right. Click it and the browser saves that document under its original name.
Extracting everything
Above the file list, Download all (ZIP) packs every document into one ordinary ZIP archive. The technical files (mimetype, META-INF) are left out, so the archive contains exactly what a person would call "the documents".
What you get
| Property | Result |
|---|---|
| Content | Byte-identical to the signed file |
| File name | Preserved, including õ, ä, ö, ü, š, ž |
| Folder structure | Preserved in the ZIP |
| Signatures | Not included; they stay in the container |
Extraction and integrity
Because the viewer has already compared each file with its digest in the signature, an extracted file from a container marked "Integrity OK" is exactly what the signers approved. If a file is flagged as changed, extract it knowing that it differs from the signed version.
Nested containers
Sometimes a container holds another container, most often a .ddoc inside an .asics. The extractor offers two choices for such a file: download it as it is, or press Open container to step inside and extract the documents from the inner one.
Extracting from other signed formats
- BDOC, EDOC, ADOC: identical procedure; they are ZIP-based.
- DDOC: documents are stored as Base64 text inside XML. The extractor decodes them back into real files.
- P7M: the wrapped document is pulled out of the signature.
After extraction
Remember what the files are: copies for working with. For a record of who signed, keep the container alongside them. A tidy folder might look like contract.asice plus an extracted subfolder.
On a phone
On Android, the ASiC-E Viewer app saves any document from a container to a location you choose, and nothing is written without your confirmation. Manual ways to extract, including command-line ones, are described in extract files from ASiC-E.
Frequently asked questions
Does extracting change the container?
No. The container is read only; the extracted files are new copies.
Why is the ZIP from "Download all" smaller than the container?
It contains only the documents. Signatures and technical files are not included.
