WIF checksum

[evanuz]

Hey, i am trying to make a validation of WIF (Wallet Import Format).

Following the wiki: https://en.bitcoin.it/wiki/Wallet_import_format

In step two, i have to Convert it to a byte string using Base58Check encoding

I am using python , therefore:

Code:

import base58
hexwif=str.encode("5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ") 
enco=base58.b58encode_check(hexwif)
data=bytes(enco,"ascii")
l=list(data)

If i print data it gives me this output

[75, 120, 109, 118, 51, 117, 90, 90, 107, 69, 50, 100, 99, 89, 107, 65, 115, 113, 97, 99, 115, 90, 76, 70, 100, 82, 103, 52, 87, 102
, 97, 109, 66, 109, 115, 53, 84, 101, 120, 87, 111, 97, 68, 71, 114, 109, 102, 75, 105, 119, 82, 82, 98, 54, 87, 114, 89, 104, 69, 7
1, 117, 117, 90, 81, 53, 49, 103, 99, 80, 109, 101, 107, 104, 71, 107]

Which is different from what i should obtain according to the wiki.

Can somebody help me??

Thanks

Since the string you have is ALREADY base58check encoded, and you want to decode it back to its original bytes, try using:

enco=base58.b58decode_check(hexwif)

instead of

enco=base58.b58encode_check(hexwif)

Thanks for the reply

I have tried it like this:

Code:

import base58
hexwif=str.encode("5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ") 
enco=base58.b58decode_check(hexwif)

And the output of enco is:

Code:

>>> enco
b"\x80\x0c(\xfc\xa3\x86\xc7\xa2'`\x0b/\xe5\x0b|\xae\x11\xec\x86\xd3\xbf\x1f\xbeG\x1b\xe8\x98'\xe1\x9dr\xaa\x1d"

Which looks more similar to what i should get but some parts are different is it because of some encoding i should convert it again?

Oh i find out it has to be converted to hex Thx anyway
