Hi, why do you generate your private key in base58 ? If you are looking for an example I made a tutorial here (https://www.insacoin.org/blog/shiba-lion-third/) and (kind of) a Python library here (https://github.com/darosior/bitcoineasy/blob/995b98f9c440aa4fa3c428750f51b7a59b327fad/bitcoineasy/keys.py#L7).

a Python library here (https://github.com/darosior/bitcoineasy/blob/995b98f9c440aa4fa3c428750f51b7a59b327fad/bitcoineasy/keys.py#L7).
why are you rounding N (https://github.com/darosior/bitcoineasy/blob/995b98f9c440aa4fa3c428750f51b7a59b327fad/bitcoineasy/keys.py#L4)? That is not the correct value. I am not really familiar with python but you may need to change sizeof(x) and sizeof(y) here (https://github.com/darosior/bitcoineasy/blob/995b98f9c440aa4fa3c428750f51b7a59b327fad/bitcoineasy/keys.py#L69-L74) to a hardcoded value '32' instead since x and y can be less than 32 bytes but you must return them with zeros appended. Here is a unit test that must pass: Private key: 128b87b572c379e92d8dd9f2f89118ec0bd8fe7ad6214312486d572d8718f8c7
public key: 04C7F4A880E496EE7335424E9613E7B29D37CEF9151DE1751D44E9159C699E07A20038BF72B3FF4FC35F1A6FF2E43F56DC4D5743BE3AFF67F1A7C5F6A9F227B47C
To OP: You need to use another library on top of this one. You call your GetPrivateKey(shortKey) function with your mini private key and it will return an actual private key in hexadecimal formal. Then pass that into a key function in that library. Check out https://github.com/warner/python-ecdsa for example.
