Create CAdES-T Signature using Aruba TSA Server (servizi.arubapec.it)

See more CAdES Examples

Demonstrates how to create a signature with an external timestamp (using the Aruba TSA Server) that certifies the time of signing.

Note: This example requires Chilkat v9.5.0.79 or greater.

; On Windows systems, it is also possible to use certs on smartcards/usb tokens or certs pre-installed in the Windows registry.

; A CAdES-T signature is one that includes a timestampToken created by an online TSA (time stamping authority).
; We must include the TSA's URL, as well as a few options to indicate what is desired.
; This example uses the Aruba TSA server, which requires a login/password for the HTTPS request.

; The tsaUsername/tsaPassword feature was added in Chilkat v9.5.0.79.
; Make sure you are using a version of Chilkat that is no older than v9.5.0.79
