Keybase proof

I hereby claim:

• I am bumblefudge on github.
• I am by_caballero (https://keybase.io/by_caballero) on keybase.
• I have a public key ASBHmmPVqPqk7K5-B9BODVJRwJNWn6kCtV-7RKtLxpF17Ao

To claim this, I am signing this object:

DID syntax can be kind of confusing and arbitrary-seeming but it's basically just like URNs, an heirarchy of arbitrary schemata.  Here's a tutorial on expressing public keys (or their hashed "address" forms popular in cryto networks) "as street-legal DIDs".

If it's a public key, the most common syntax is a `did:key`[^1]:
```
did:key:<base58btc multibase(<pub key bytes appropriately multicodeced>)>
```
The magic number in this case is 0xe7 [^2], which you'll want to prepend to the raw bytes.
Note that if you've never used `multiformats` before and you're not using IPFS/Protocol-Labs tooling, there's a step some people miss: you have to pad the raw bytes into an "unsigned varint"[^3] before base58btc-encoding but after prepending the magic number.
One nice sideeffect of this padding + prefacing with a byte or two of sigil is that once ASCII-encoded, there ends up being a one-character prefix that is constant for each major key type to date [^4].
