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
