pybtctool1

Command interface for bitcoin signatures and transactions

Usage

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

Overview

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
