TimeCert is a service for timestamping content. This provides evidence that something existed at a given time. TimeCert will give you the timestamp for when someone first referenced a given digest.

A Digest is like a fingerprint for a chunk of data. It looks like this: a94a8fe5ccb19ba61c4c0873d391e987982fbbd3

An application can generate this digest easily. Technically speaking it is a Hex encoded SHA1 digest.
