Woodpecker - The Transparency Log Inspector

Woodpecker is a command-line tool that launches a UI to inspect logs.

To run it:

# From a local checkout
go run .

# Without a local checkout:
go run github.com/mhutchinson/woodpecker@main

To change the default log that is displayed, the --origin flag can be provided:

# This will show the contents of the Go SumDB by default:
go run github.com/mhutchinson/woodpecker@main --origin "go.sum database tree"

Features:

• q or <Ctrl-c> to quit
• Left/Right arrows: previous/next leaf
• l: show the log selector to switch to a different log
• g: jump to a specific leaf
• w/W: increment/decrement the number of witness signatures to query

Roadmap (flight plan?)

• Support log switcher to other serverless logs
• Support getting witnessed checkpoints from distributor
• Support logs other than serverless
• Support generating an offline inclusion proof bundle for the selected leaf including witness sigs
• Custom leaf renderer (needed if leaf data is not text-friendly)
