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
