aprirep7m.app

aprirep7m.app is a browser-based tool for opening and extracting content from P7M files (CAdES/CMS digital signature envelopes). Users can drag and drop P7M files directly into the application to preview the signed document, verify signer information, and extract the contained PDF or XML files without installing any software.

Key features include automatic CMS/CAdES structure detection, signer verification with certificate details, timestamp validation, support for multiple signatures, and secure processing with files never leaving the user's device. The tool handles various P7M scenarios including incorrectly named files, base64-encoded files, multi-signed documents, and provides free preview with paid full document access.

The product is designed for professionals who regularly receive digitally signed documents via PEC (Italian certified email), invoices, contracts, and need a quick way to access and extract the underlying files on desktop or mobile devices without additional software installation.
