| Name | Description |
|---|
| Authority { get; set; } | The name of the person or authority signing the document. |
| ByteRange { get; } | An array of pairs of integers (starting byte offset, length in bytes) that shall describe the exact byte range for the digest calculation. |
| ContactInfo { get; set; } | Information provided by the signer to enable a recipient to contact the signer to verify the signature, e.g. a phone number. |
| CustomAppearance { get; set; } | Gets/sets the custom appearance. |
| CustomSignHash { get; set; } | The delegate for custom sign the document hash (Beta). |
| Date { get; set; } | The time of signing. |
| Location { get; set; } | The CPU host name or physical location of the signing. |
| OcspSettings { get; set; } | Gets/sets ocsp settings. |
| Reason { get; set; } | The reason for the signing, such as (I agree…). |
| ShowProperties { get; set; } | Force to show/hide signature properties. In case ShowProperties is true signature field has predefined format of appearance (strings to represent): ——————————————- Digitally signed by {certificate subject} Date: {signature.Date} Reason: {signature.Reason} Location: {signature.Location} ——————————————- where {X} is placeholder for X value. Also signature can have image, in this case listed strings are placed over image. ShowProperties is true by default. |
