NAME

       pybtctool - command interface for Bitcoin signatures and transactions

SYNOPSIS

       pybtctool [-sBbJj] COMMAND [, COMMAND_ARG] ...

DESCRIPTION

       pybtctool has a set of commands for interacting with the Bitcoin network.

       With  a  command,  you  can  generate  a  signature,  hash, seed, or address; serialise or
       deserialise standard data formats; query the blockchain; and many more operations.

OPTIONS

       -s     The -s option lets you read arguments from the command line.

       -b     The -b option lets you read binary data as an argument.

       -j
       -J     The -j option lets you read JSON from the command line (-J to  split  a  JSON  list
              into multiple arguments).

COMMANDS

       Presently supported commands are:

   Key manipulation
       privkey_to_pubkey
              privkey -> pubkey

       privtopub
              privkey -> pubkey

       pubkey_to_address
              pubkey -> address

       pubtoaddr
              pubkey -> address

       privkey_to_address
              privkey -> address

       privtoaddr
              privkey -> address

   Key arithmetic
       add    key1 key2 -> key1 + key2 (works on privkeys or pubkeys)

       multiply
              pubkey privkey -> returns pubkey * privkey

   ECDSA operations
       ecdsa_sign
              message privkey -> sig

       ecdsa_verify
              message sig pubkey -> True/False

       ecdsa_recover
              message sig -> pubkey

   Random data
       random_key
              -> privkey

       random_electrum_seed
              -> electrum seed

   Electrum operations
       electrum_stretch
              seed -> secret exponent

       electrum_privkey
              seed or secret exponent i type -> privkey

       electrum_mpk
              seed or secret exponent -> master public key

       electrum_pubkey
              seed or secret exponend or mpk -> pubkey

   BIP-32 operations
       bip32_master_key
              seed -> bip32 master key

       bip32_ckd
              private or public bip32 key i -> child key

       bip32_privtopub
              private bip32 key -> public bip32 key

       bip32_extract_key
              private or public bip32_key -> privkey or pubkey

   Transaction operations
       deserialize
              hex or bin transaction -> JSON tx

       serialize
              JSON tx -> hex or bin tx

       mktx   inputs outputs -> tx

       mksend inputs outputs change_addr fee -> tx

       sign   tx i privkey -> tx with index i signed with privkey

       multisign
              tx i script privkey -> signature

       apply_multisignatures
              tx i script sigs -> tx with index i signed with sigs

       scriptaddr
              script -> P2SH address

       mk_multisig_script
              pubkeys k n -> k-of-n multisig script from pubkeys

       verify_tx_input
              tx i script sig pub -> True/False

       tx_hash
              hex or bin tx -> hash

   Blockchain operations
       history
              address1 address2 etc.  -> outputs to those addresses

       unspent
              address1 address2 etc.  -> unspent outputs to those addresses

       fetchtx
              txash -> tx if present

       pushtx hex or bin tx -> tries to push to blockchain.info/pushtx

   Serialisation operations
       access JSON list or object prop -> desired property of that json object

       multiaccess
              JSON list prop -> like access, but mapped across each list element

       slice  JSON list start end -> given slice of the list

       count  JSON list -> number of elements

       sum    JSON list -> sum of all values
