Zcash extends the Bitcoin Core API with new RPC calls to support private Zcash payments.
z_exportkey | zaddr | _Requires an unlocked wallet or an unencrypted wallet._<br><br>Return a zkey for a given zaddr belonging to the node’s wallet.<br><br>The key will be returned as a string formatted using Base58Check as described in the Zcash protocol spec.<br><br>Output:AKWUAkypwQjhZ6LLNaMuuuLcmZ6gt5UFyo8m3jGutvALmwZKLdR5
z_importkey | zkey [rescan=true] | _Wallet must be unlocked._<br><br>Add a zkey as returned by z_exportkey to a node's wallet.<br><br>The key should be formatted using Base58Check as described in the Zcash protocol spec.<br><br>Set rescan to true (the default) to rescan the entire local block database for transactions affecting any address or pubkey script in the wallet (including transactions affecting the newly-added address for this spending key).
z_exportwallet | filename | _Requires an unlocked wallet or an unencrypted wallet._<br><br>Creates or overwrites a file with taddr private keys and zaddr private keys in a human-readable format.<br><br>Filename is the file in which the wallet dump will be placed. May be prefaced by an absolute file path. An existing file with that name will be overwritten.<br><br>No value is returned but a JSON-RPC error will be reported if a failure occurred.
-z_importwallet | filename | _Requires an unlocked wallet or an unencrypted wallet._<br><br>Imports private keys from a file in wallet export file format (see z_exportwallet). These keys will be added to the keys currently in the wallet. This call may need to rescan all or parts of the block chain for transactions affecting the newly-added keys, which may take several minutes.<br><br>Filename is the file to import. The path is relative to zcashd’s working directory.<br><br>No value is returned but a JSON-RPC error will be reported if a failure occurred.

z_exportviewingkey | zaddr | Reveals the viewing key corresponding to 'zaddr'. Then the z_importviewingkey can be used with this output.
z_importviewingkey | vkey [rescan=whenkeyisnew] [startHeight=0] | Adds a viewing key (as returned by z_exportviewingkey) to your wallet.
