Built for signed documents
Digitally signed files are commonly used for contracts, invoices, public procurement documents, legal filings and official communications.
Although these formats are widely used by businesses and public institutions, macOS does not provide a simple built-in way to inspect or extract their contents.
P7S Verifier provides a fast and secure workflow designed specifically for Mac users.
Supported formats
P7S Verifier currently supports:
– P7S signed document containers
– P7M / CAdES signed files
– ASiC-E containers
– ASiC-S containers
– Embedded PDF, XML and other supported document types
Support may vary depending on the structure and contents of individual containers.
