Auto merge of #3492 - str4d:zip32, r=str4d
Use ZIP 32 for all Sapling spending keys The wallet now only stores Sapling extended spending keys, and thus can only be used with keys generated from an HDSeed via ZIP 32. This means that all Sapling keys and addresses generated by users can be recovered as long as they have a backup that includes the seed. Depends on zcash/librustzcash#29 Closes #3380.

Hierarchical Deterministic Key Generation for Sapling
|
||||
-----------------------------------------------------
|
||||
All Sapling addresses will use hierarchical deterministic key generation
|
||||
according to ZIP 32 (keypath m/32'/133'/k' on mainnet). Transparent and
|
||||
Sprout addresses will still use traditional key generation.
|
||||
|
||||
Backups of HD wallets, regardless of when they have been created, can
|
||||
therefore be used to re-generate all possible Sapling private keys, even the
|
||||
ones which haven't already been generated during the time of the backup.
|
||||
Regular backups are still necessary, however, in order to ensure that
|
||||
transparent and Sprout addresses are not lost.
|
||||
