Build the form, key the link, sign in one pass.

A working end-to-end demo: lay out the document and its fields, deliver it as a link locked behind an access key, then sign every field from one adopted mark.

Prepare

Import the contract you already have — .docx, .pdf, .rtf or pasted text — or write one here. Sigil finds the signature lines; you place the rest.

Deliver

Sending mints a link with an envelope token plus a six-character access key you share separately. Only the key hash is stored.

Sign

The recipient unlocks with the key, adopts a signature once, and works the field list until Finish unlocks.

Your envelopes

Bring your own contract

Drop the file you already have. Sigil reads it, splits it into pages and clauses, and finds the places it thinks need signing.

Envelope sent

The link below opens the signing session. The access key is deliberately not in it — send the key by a different channel, the way you would a door code.

Envelope token
This is the only time the key is shown in full. Sigil keeps the hash, so a leaked envelope store cannot be used to open the document — but it also means a lost key has to be reissued, not recovered.
