Index of Module timestamp

Module: timestamp

Provides support for trusted timestamping (RFC 3161). See https://en.wikipedia.org/wiki/Trusted_timestamping for examples.

Note: The default server declared here is run by the German National Research and Education Network (DFN), which doesn't allow commercial use. See https://www.pki.dfn.de/zeitstempeldienst/. You can easily switch to a different provider using (timestamp-host-set! hostname) and (timestamp-url-set! url)
