Different kinds of tool interact with a keyset in different ways. This hub groups them by intent rather than by name, because a page that lists software is a thin download page, whereas a page that explains what a category of tool expects from a keyset is actually useful.
What every tool page covers
- Expected keyset format. What structure and naming the category assumes.
- Configuration. How the tool is told where the keyset lives.
- Keyset recognition. How the tool decides a file is a keyset at all.
- Compatibility. Which revision or environment the tool expects.
- Common errors. The messages the category tends to produce, and what each one means.
Why this site does not host tools
Hosting a tool would make this site responsible for a file it cannot audit, and it would turn a reference into a distribution point. The tool pages describe behaviour and failure modes. They do not redistribute software.
Start with structure, not software
When something fails, the cause is more often structural than software-specific. Before changing tools, confirm that the keyset is well-formed and in the expected location — the file-structure guide and format validators cover that ground.
