上面的程式碼獲取比特幣公鑰地址，一些公鑰錯誤發生

private key is 0x5c58d

public key pairs

x =  0x5bd8834885082d9e9775f2084610bea79d2bd7acde2fc28b4dba85b0902ac786L
y1 =  0xef3a1fa082da527a3a51bcd71104b4e6ef91b62b2e93bcfdbc4ac7c35e9fddbL
y2  =  0xf10c5e05f7d25ad85c5ae4328eefb4b19106e49d4d16c430243b5382ca15fe54L

公鑰 x 和 y1 出錯

公鑰 x 和 y2 沒有錯誤

您收到錯誤是因為您提供的十六進製字元串長度為 127 個字元。你需要用零填充。

即使您用零填充05bd8834885082d9e9775f2084610bea79d2bd7acde2fc28b4dba85b0902ac786ef3a1fa082da527a3a51bcd71104b4e6ef91b62b2e93bcfdbc4ac7c35e9fddb也不是有效的公鑰。它必須以 04 開頭。

您的公鑰的座標 y1、y2 也不在曲線上。我不知道你從哪裡得到你的鑰匙，但它是無效的。

Private Key對應的Public Key0x5bd8834885082d9e9775f2084610bea79d2bd7acde2fc28b4dba85b0902ac786是04b302d50e6afaea3eb3194fced5b12ba45aa170d2d717d5a598511a96187a7a90e8c84b1f57a822bda9ecf111374c9e92fe0d1fb5a192a45790f437828d17f009，P2PKH地址是14pFAXD2uQpdpToL5LS4oh1bsSGXnVpA2r
