Notable changes

zcash-cli: arguments privacy

The RPC command line client gained a new argument, -stdin to read extra arguments from standard input, one per line until EOF/Ctrl-D. For example:

$ src/zcash-cli -stdin walletpassphrase
mysecretcode
120
^D (Ctrl-D)

It is recommended to use this for sensitive information such as private keys, as command-line arguments can usually be read from the process table by any user on the system.

Asm representations of scriptSig signatures now contain SIGHASH type decodes

The asm property of each scriptSig now contains the decoded signature hash type for each signature that provides a valid defined hash type.

The following items contain assembly representations of scriptSig signatures and are affected by this change:

  • RPC getrawtransaction
  • RPC decoderawtransaction
  • REST /rest/tx/ (JSON format)
  • REST /rest/block/ (JSON format when including extended tx details)
  • zcash-tx -json

For example, the scriptSig.asm property of a transaction input that previously showed an assembly representation of:

304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c509001

now shows as:

304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c5090[ALL]

Note that the output of the RPC decodescript did not change because it is configured specifically to process scriptPubKey and not scriptSig scripts.
