Python Tool of Base58 Decode Check

Base58 originates from bitcoin where the inventor Satoshi intentionally removes "iILloO0" which are confusing letters/digits when they appear in printing..

Base58 uses the following character set:

123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz

In Blockchain such as bitcoins or Tron, the public wallet address is computed from private keys (256 bit random bytes). The wallet address is a base58 string, and we can decode and check the checksum. The following is a Python command line tool that uses the base58 library to perform the b58decode_check for the addresses.

import sys

def address_hex(address):
    arr = base58.b58decode_check(address).hex().lower()
    s = []
    for i in range(0, len(arr) - 1, 2):
        s.append("0x" + arr[i] + arr[i + 1])
    return "{" + ",".join(s) + "}"

if len(sys.argv) <= 1:
    print("Usage: " + sys.argv[0] + " str1 str2 ...")
    exit()

for i in sys.argv[1:]:
    print(i)
    print(address_hex(i))

For example:

$ python3 b58.py TFczxzPhnThNSqr5by8tvxsdCFRRz6cPNq TSSMHYeV2uE9qYH95DqyoCuNCzEL1NvU3S

{0x41,0xb4,0xa4,0x28,0xab,0x70,0x92,0xc2,0xf1,0x39,0x5f,0x37,0x6c,0xe2,0x97,0x03,0x3b,0x3b,0xb4,0x46,0xc1}
