Struct HsIdKeypair

pub(crate) struct HsIdKeypair(ExpandedKeypair);
Expand description

The private counterpart of a [`HsIdKeyKey’].

This is stored as an expanded secret key, for compatibility with the C tor implementation, and in order to support custom-generated addresses.

(About custom generated addresses: When making a vanity onion address, it is inefficient to search for a compact secret key s and compute SHA512(s)=(a,r) and A=aB until you find an s that produces an A that you like. Instead, most folks use the algorithm of rend-spec-v3.txt appendix C, wherein you search for a good a directly by repeatedly adding 8B to A until you find an A you like. The only major drawback is that once you have found a good a, you can’t get an s for it, since you presumably can’t find SHA512 preimages. And that is why we store the private key in (a,r) form.)
