It turns out that in order to Bech32 encode something the data needs to be in base 5. At least with the library I'm using. It only took me like 4 hours to figure this out. I'm still a little confused because the Bitcoin wiki includes steps for sha256 and RIPEMD-160 hashing in the encoding process, but nostr clients don't seem to do that part? https://en.bitcoin.it/wiki/Bech32
