Package dgs.tlkt Description

The SecureTime API is a set of objects that support the process of creating time stamps using an Internet based time stamp service. The process includes:

1. Configuring you Internet communications preferences for reliable access to the time stamp servers (time-outs, SSL, failover, etc.)
2. Create a time stamp request and send it via the Internet to the time stamp server(s)
3. Verify the time stamp signature and your trust of the public key certificate

The complexity of this API can be best understood by reviewing "demo" source code that is supplied with the toolkit. The demos were intended to get you up and running quickly.
