Which MIME types are related to file extension ".asice"?
The .asice file extension is associated with 2 MIME types:
application/vnd.etsi.asic-e+zip, application/x-bdoc.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .asice Files
ASICE files are digital signature containers used to bundle documents with their accompanying digital signatures.
They use a zip-based structure per the MIME type application/vnd.etsi.asic-e+zip, following ETSI standards for secure digital transactions. This ensures the integrity and authenticity of contents, often used in legal and government applications.
They also relate to the MIME type application/x-bdoc, which denotes a binary document container. This underlines the file’s role in handling securely packaged digital signatures.
- Digital Signatures: They carry digital signature data tied to one or several documents.
- Security & Authenticity: They help verify the origin of the documents and guard against tampering.
- ETSI Standards: They adhere to European Telecommunications Standards Institute protocols.
- Specialized Software: Applications such as DigiDoc Suite and other digital signature verification tools can open, view, or edit these files.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an ASICE file and what is it used for?
An ASICE file is a secure digital container used to store documents along with their digital signatures. It adheres to the ETSI ASiC-E (Associated Signature Containers - Extended) standard, ensuring that the enclosed files have not been tampered with and confirming the identity of the signer. These are commonly used for legal contracts and government documents in Europe.
How do I open an ASICE file on Windows or Mac?
You need specialized digital signature software to open and verify these files properly. The most common tool is the DigiDoc4 Client (part of the Open-EID software), which allows you to view the signed documents and check the signature validity. Without this software, you cannot easily verify who signed the document.
Can I convert an ASICE file to PDF?
You cannot convert the container itself directly to PDF, but you can extract the PDF documents contained within it. By opening the .asice file in software like DigiDoc, you can save the original signed files (which are often PDFs, Word docs, or images) to your computer for normal viewing.
Why does the ASICE file look like a ZIP archive?
The ASiC-E standard is actually based on the ZIP format. If you rename the file extension from .asice to .zip, you can often open it with standard archive tools to see the raw contents, such as the document and the signature XML files. However, this method breaks the digital signature verification process.
How do I create an ASICE file?
You create an ASICE file by digitally signing a document using an electronic ID (eID), Smart-ID, or Mobile-ID. When you use software like DigiDoc4 to sign a file (e.g., a PDF or DOCX), the program wraps the original file and your cryptographic signature into a new .asice container automatically.
What is the correct MIME type for ASICE files?
The standard MIME type for these files is application/vnd.etsi.asic-e+zip. Web servers should be configured with this type to ensure browsers handle the file correctly during downloads. You can learn more about this configuration at mime-type.com.
Are ASICE files compatible with mobile devices?
Yes, but you usually need a specific app to open them. On Android or iOS, you can use the RIA DigiDoc application to open, view, and even sign .asice containers. Standard mobile file viewers will likely not recognize the format without this third-party app.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
