SignatureConfiguration Properties

Whether to add a trusted time-stamp to the signature

The visual appearance of the signature

The visual appearance or to create a signature without a visual appearance.

Default:

The contact information of the signer

Whether to embed validation information into the signature (LTV)

• : Create an LTV signature by embedding validation information (see EmbedInSignature). This value is only supported, if the SignatureFormat is AdbePkcs7Detached. LTV signatures for other formats can be created by adding validation information to the signed document (see Process(Document, Stream, OutputOptions, Provider) and AddValidationInformation).
• : Create a basic signature without validation information (see None).

Default:

The name of the existing signature field

The FieldName of an existing, unsigned signature field to sign. Note that when an existing signature field is signed, the appearance's position is defined by the existing field. Therefore, make sure the Appearance fits into the BoundingBox.

If a new signature field is created using a unique field name.

Default:

The message digest algorithm

The algorithm used to hash the document and from which the cryptographic signature is created.

Default: Sha256

The location of signing

The name of the signing certificate

The reason for signing

The format (encoding) of the cryptographic signature
