带有Python错误的比特币地址生成 [英] Address generation for bitcoin with Python error

问题描述

我试图用python理解比特币，并试图创建自己的虚荣地址生成器.

I am trying to understand bitcoin with python and trying to create my own vanity address generator.

下面是while循环的一小段.循环运行大约10次后，我一直收到错误消息.任何帮助将不胜感激.我已经搜索了论坛并找到了答案.

Below is a snippet of the while loop. I keep getting an error after the loop runs about 10 times. Any help would be highly appreciated. i have searched the forum and have found answers.

但是它们不起作用.IE.我更改了

But they don't work. IE. i changed the

intermed = hashlib.sha256(string).digest() 

几次修改代码，但结果仍然相同.

a few times modifying the code but still the same result.

推荐答案

您必须对 hex_compressed_public_key 进行编码才能生成地址.

You have to encode your hex_compressed_public_key to generate the address.

compressed_address_base58check = bitcoin.pubkey_to_address(hex_compressed_public_key.encode('utf-8'))
