What is an .adoc file?

ADOC is Lithuania's national electronic document specification (ADOC-V1.0), used by public institutions and document management systems there. The file is a ZIP container holding the main document, attachments, metadata and XAdES signatures in the META-INF/signatures folder.

ASiCE Viewer unpacks the .adoc file in the browser, lists every file in it and reads the signer's name and the signing time from the signatures.
