使用 Openssl 簽署 P2SH 交易

我有一個 P2SH 1-3，我想使用 openssl 簽署交易。我的贖回腳本是

我的交易數據是：

在裡面你可以找到兌換腳本和 SIGHASH。

我做了兩次 SHA256 並將其保存在a.txt文件中

printf $A | xxd -r -p | sha256sum -b | xxd -r -p | sha256sum -b | xxd -r -p > a.txt

現在我可以用我的私鑰簽名了

FIRMA=`openssl pkeyutl -inkey chiave_priv_1.pem -sign -in a.txt -pkeyopt digest:sha256 | xxd -p -c 256`

附加到FIRMA字節 01 (SIGHASH_ALL) 並為 OP_CHECKMULTISIG 的錯誤添加長度和 OP_0。

我的目標是創建自定義腳本。我什至嘗試了 2-3 但沒有幸運。

安德魯回答後的更新問題

您簽署的交易數據有誤。對於 P2SH，您實際上必須簽署redeemScript，而不是scriptPubKey。你必須像那個redeemScript 是scriptPubKey 一樣簽署它。

---

您的redeemScript 中還有另一個錯誤。AnOP_CHECKMULTISIG要求您推送所需的簽名者數量，然後是密鑰，然後是密鑰數量。因此，對於您所擁有的 1-of-3，它應該是

1 <key1> <key2> <key3> 3 OP_CHECKMULTISIG

但是你有

1 <key1> <key2> <key3> 1 OP_CHECKMULTISIG

這使得整個redeemScript 本身無效。

你的redeemScript 真的應該是

因為redeemScript 無效，所以您嘗試花費的輸出也是無效的，因此是不可花費的。
