+STFE is a Trillian personality that allows you to log signed artifact checksums.
+A client consuming artifacts (such as a browser update, a Debian package, a document,
+or more generally anything opaque) may enforce that such logging takes place by

an arbitrary identifier like `stfe_client v0.0.1`,
- an artifact checksum,
+ a checksum,
a signature, and
a namespace that is derived from the public verification key.
Tracking checksums as opposed to full-on artifacts makes it less costly to
