Convert list of BTC address(base58) to Ripemd16(base16)

Are there online tool or repositories that can convert multiple base58 (BTC address) to base16 simultaneously?

what do you need? the address is hash160. are you looking for a tool for converting from base58 to base16 (aka hex)? – amaclin – 2017-11-22T07:04:28.133

Hello @amaclin sorry about that, I mean base58(BTC address) to ripemd160. I need a tool that can convert multiple address simultaneously. – Nael Cruz – 2017-11-22T08:00:01.450

I see you do not understand this. Can you provide an example of one pair (A,B) where A is what you have and B is what you want before asking a tool? – amaclin – 2017-11-22T08:25:46.083

Alright. A is 1CiezJhGh4YqT1gv4NuBJ9pQAXSFkSEXXG I need to find B which is 808a261b6a7b67371958523913a035274fe4c4d0 – Nael Cruz – 2017-11-22T08:30:03.263

Both A and B are hash160 outputs, which is the source of the confusion here. The only difference is the representation of the values. A is encoded as base58 and B as base16 (hex). I suggest you edit the question to reflect this. – Daniel R – 2017-11-22T10:18:15.343

In Go, you can do this very easily:

package main

import (
    "fmt"

    "github.com/btcsuite/btcutil/base58"
)

var addresses = []string{
    "1Nh7uHdvY6fNwtQtM1G5EZAFPLC33B59rB",
    "1Le1ttNd2GQ79212Epyciw39JDy2E6DYWf",
    "1LpRieyPAZfFyUSMGiZhwAarQoJw1Y8pEx",
}

func main() {
    for _, address := range addresses {
        ripemd160, _, err := base58.CheckDecode(address)
        if err != nil {
            fmt.Printf("Failed to decode address %s: %s\n", address, err)
            continue
        }

        fmt.Printf("HASH160 %x from address %s\n", ripemd160, address)
    }
}

When you have Go installed, you can run this code very easily in your terminal:

$ go get github.com/btcsuite/btcutil/base58
$ go run thefile.go
HASH160 edf10a7fac6b32e24daa5305c723f3de58db1bc8 from address 1Nh7uHdvY6fNwtQtM1G5EZAFPLC33B59rB
HASH160 d76a86f903b33835f06d7b18a1429a8f249f3ab1 from address 1Le1ttNd2GQ79212Epyciw39JDy2E6DYWf
HASH160 d96292e45d045d2269a818b96b13422555557d85 from address 1LpRieyPAZfFyUSMGiZhwAarQoJw1Y8pEx

Hi @Steven can it just accept a txt file consisting the base58? Since I have thousands of base58 to convert. Thank you. – Nael Cruz – 2017-11-22T10:19:37.637

@NaelCruz this should work: https://gist.github.com/stevenroose/de1cdd183b1d3b9a6e5a5623a4ca969a

-2

static const QByteArray convert ( const QLatin1String& buf )
{
  QByteArray ret;
  ret.resize ( 20 );
  quint8 addr [30];
  BASE58::decodeBase58 ( buf.latin1 ( ), addr, 26, true );
  memcpy ( ret.data ( ), addr + 1, 20 );
//printf ( "%s\n", ret.toHex ( ).constData ( ) );
  return ret.toHex ( );
}

Oups, sorry. This is not an answer if you are looking for online solution
