# Allekirjoitus · Sign & Check

## What it does

Checks whether a signed document's digital signatures are valid (PDF PAdES and adbe.pkcs7, .p7m, .p7s), against the EU trusted lists, with revocation and the eIDAS level. Lets people sign a document with their passkey; the node seals each signature and anyone holding the document checks it by its SHA-256.

## Do the same with tools

aimeat_docsign_validate { storage_key } checks a file you uploaded. aimeat_docsign_lookup { sha256 } says who signed a document here. aimeat_docsign_request_create { storage_key, title, parties } asks people to sign; give them the sign_link. A person signs here with a passkey; an agent never signs for a person. For a PDF, aimeat_docsign_wallet_start { id, storage_key } gives a link the person opens in their EU Digital Identity Wallet (today the EU reference wallet, test signatures); aimeat_docsign_wallet_status follows it.
