Thanks!

btw it's not clear how H() output should be truncated to form a
checksum. Should it be the first 2 bytes or the last 2 bytes?
It should be specified in the definition of CHECKSUM (because length of
digest obviously is not 2 bytes):

- CHECKSUM = H(".onion checksum" || PUBKEY || VERSION)
+ CHECKSUM = H(".onion checksum" || PUBKEY || VERSION)[:2]


Also it worthwhile to include examples with correct checksums.
