ASiC-E and ASiC-S are the two forms of the Associated Signature Container (ETSI EN 319 162), both ZIP packages that keep files with their signatures. ASiC-E (Extended) holds multiple files and signatures; ASiC-S (Simple) holds a single data object with one signature or timestamp.
| ASiC-E | ASiC-S | |
|---|---|---|
| Data files | One or more | Exactly one |
| Signatures | One or more | One signature or timestamp |
| Inner signature | CAdES or XAdES | CAdES or XAdES |
| Standard | ETSI EN 319 162 | ETSI EN 319 162 |
| Best for | Multi-file datasets | A single file plus its signature |
Choosing between them
Use ASiC-S when there is exactly one document to protect, and ASiC-E when you need to bind several files together under one or more signatures. Both are ordinary ZIP files with a defined internal structure, so they are portable across systems.
