| -- = Format Specification | ||
| -- | ||
| -- The input is expected to be a serialized CBOR Map adhering to the rules defined in __RFC 8949__. | ||
| -- | ||
| -- The structure of the map is expected to be as follows: | ||
| -- | ||
| -- * **Root Object**: CBOR Map (Major Type 5). | ||
| -- * **Key 0** (@Unsigned Int@): Protocol Version or Algorithm Identifier. | ||
| -- * **Key 1** (@Unsigned Int@): **The Prekey ID** (Target of extraction). | ||
| -- * **Key 2** (@Map@): The raw Public Key material (often a nested COSE-like structure). | ||
| -- | ||

There was a problem hiding this comment.
Instead of this comment, can we please write a type and parse things into it? Then the comment could just be a link to the spec.
This would also make the code much simpler because we're now parsing into a generic CBOR term.

| -- 2. The input is not valid CBOR data. | ||
| -- 3. The root object is not a Map. | ||
| -- 4. The key @1@ is missing from the Map. | ||
| -- 5. The value associated with key @1@ is not an integer. |

This is gonna go stale as soon as someone touches it. If we really want this, we should create an error type. Otherwise, I'm also ok with just deleting this part.
