About ASICS files
The .ASICS (Associated Signature Container Simple) file is a specialized ZIP-based container used to bundle a single electronic document with a detached digital signature. Created by the ETSI to standardize electronic signatures, it is heavily used for legally binding digital contracts. Specialized software like DigiDoc or an official XAdES Signature Checker is required to verify the signatures natively. Users struggle with .ASICS files because standard operating systems do not recognize the extension. This makes the embedded document inaccessible without installing localized government software. Furthermore, these files are strictly read-only; altering the internal document instantly invalidates the cryptographic signature. The most practical conversion target is the embedded document itself, typically a PDF, DOCX, or XML file. Extracting the file discards the digital signature validation but recovers the readable text. Standard online converters fail to process this format because they lack the ability to parse the internal cryptographic layers. Our system bypasses the signature restrictions to extract and convert the underlying document format.
Convert.Guru analyzes your ASICS file, detects the exact format, and lets you read the text inside.
If you want to convert ASICS file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use DigiDoc or similar software from the "Digital Signature Container" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to ASICS, try DigiDoc or another comparable tool in the "Digital Signature Container" category.
The ASICS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ASICS converter.
