Signing | Runstamp Docs

pdf.transform.sign signs PDF bytes (PAdES, CMS detached) and returns the signed file. @runstamp/registry is the internal binding name, not a separate install; call the operation through @runstamp/sdk as rs.sign.

Install

Terminal

npm install @runstamp/sdk

Behavior

The original bytes are kept as the prefix of the output; the signature is appended.
The page count and form values are unchanged. Signing after a fill keeps the filled values.
The hosted runtime signs with an identity made for the call (self-signed, named in the signature panel through the name option). A deployment with its own certificate sets its own signer.
Options: field, page, rect, name, reason, location.

Operation

See pdf.transform.sign for the input, options, errors and a worked example with its input and output files.
