Base58check to decimal

[Nosferatu fist]

First Hello and thank you for any help you can give me .

here I have traveled google but I have not found my happiness . I would like to convert decimal number BASE58Check in my research but give nothing

example:
bitcoin address : 1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN
In decimal : 1037542833334494436883955695059393877833907143043

Thank you in advance for your help.

Write a for loop :)

Also are you sure that the decimal number is correct... i.e. I got a different result and http://lenschulwitz.com/base58 gives the same result.

No base58 but base58check

Yep, read the docs:

https://godoc.org/github.com/btcsuite/btcutil/base58#CheckDecode

The "check" means run SHA256 twice over the previous payload bytes and use the first 4 bytes of the result as the checksum.

Here's some code from the example that verifies your decimal value from your input address:

Not sure what the exact questions is, but I think if you study and play around with this section of code, you'll get somewhere closer to understanding how Bitcoin private keys and addresses work:

https://github.com/saracen/directory.io/blob/master/directory.go#L70-L101

The (joke) app is basically just going from 0 to the maximum possible bitcoin private key value and generating the matching address:

In the fact the author has already made it easy for you:

Also, it starts at 1, not 0 :-)
