River recalling Hal Finney's 1995 challenge to break 40-bit encryption, cracked a month later by Adam Back and three others. Registered as the historical framing that circulated during the incident, on how key-space assumptions decay. It is background rather than a claim about this defect, and the archive holds the earlier predictable-key incidents separately as the closer precedents.
This post is registered as evidence and has a locally held capture. The original remains the canonical publication. Last checked .
This post is held twice: here, with this project's own note on why it matters, and again as part of the conversation captured at , which is polled for changes. Both copies are the same post; neither is a separate event.
Snapshot and diff bodies for this chain monitor are held in the local evidence archive but withheld from the public site because they can contain the addresses of people who published nothing themselves. Capture times and reviewed change summaries remain available below.
