Verify Method

Verifies a signed PDF document.

Syntax

pdfverifier.verify([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Use this method to validate all signatures in a PDF document.

This method walks through a signed document and reports every signature via a SignatureFound event. Subscribe to the event to be notified about the signatures and adjust validation settings on the fly.

Upon completion of this method the signature details will be published in Signatures property.

This method only validates the signatures, but does not check their coverage. It is a good idea to use mechanisms such as GetSignedVersion or CoverageEndsAt to ensure that the signature covers the expected document revision.
