A microdescriptor is the smallest amount of information needed to build a circuit through a router. They are generated by the directory authorities, using information from the uploaded routerinfo documents. They are not self-signed, but are rather authenticated by having their hash in a signed networkstatus document.

| HT_ENTRY | ( | microdesc_t | ) |
Hashtable node, used to look up the microdesc by its digest.
| char* body |
A pointer to the encoded body of the microdescriptor. If the saved_location is SAVED_IN_CACHE, then the body is a pointer into an mmap'd region. Otherwise, it is a malloc'd string. The string might not be NUL-terminated; take the length from bodylen.

When was this microdescriptor last listed in a consensus document? Once a microdesc has been unlisted long enough, we can drop it.
