如何使用 Python 庫簽署交易十六進制

我有一個未簽名的交易十六進制。現在我想用我在 Python 中的私鑰簽署這個交易輸入。有沒有 Python 庫？

感謝 hartmut 解決了。

1 安裝 pybitcointools

git clone https://github.com/vbuterin/pybitcointools.git
cd pybitcointools
sudo python setup.py # I got an error in Python3. So I used Python2.

2 使用 pybitcointools 簽名

import bitcoin

def signAllIns(aTx, priv, nbIns=None):
   signedTx = aTx
   utxo = nbIns
   if utxo == None:
       utxo = len(bitcoin.unspent(bitcoin.privtoaddr(priv)))
   for i in range(utxo):
       signedTx = bitcoin.sign(signedTx, i, priv)
   return signedTx

deserializeHex = bitcoin.deserialize(HEX)
ins = deserializeHex['ins']
signedTx = signAllIns(HEX, PRIVATE_KEY, len(ins))

# Broadcast signedTx here

有pybitcointools，它允許你使用 sign(tx, index, priv) 函式來做到這一點。還有其他的，但我至少發現這個最容易使用。

編輯：你有很多我可以看到的輸入..以下可能會有所幫助

def signAllIns(aTx, priv, nbIns=None):
   signedTx = aTx
   utxo = nbIns

   if utxo == None:
       utxo = len(unspent(privtoaddr(priv)))

   for i in range(utxo):
       signedTx = sign(signedTx, i, priv)
   return signedTx

它遍歷交易的所有輸入以對它們進行簽名。
