调用trx的api会生成两个地址：1:address
2:HexAddress
其中address用来展现给用户知道.

public static String bytes2HexStr(byte[] byteArr) {
		String hexString = "0123456789ABCDEF";
		StringBuilder sb = new StringBuilder(byteArr.length * 2);
		for (int i = 0; i < byteArr.length; i++) {
			sb.append(hexString.charAt((byteArr[i] & 0xf0) >> 4));
			sb.append(hexString.charAt((byteArr[i] & 0x0f) >> 0));
		}
		return sb.toString();

	}


public static byte[] decode(String input) {
		if (input.length() == 0) {
			return new byte[0];
		}

		byte[] input58 = new byte[input.length()];

		for (int i = 0; i < input.length(); ++i) {
			char c = input.charAt(i);

			int digit58 = -1;
			if (c >= 0 && c < 128) {
				digit58 = INDEXES[c];
			}
			if (digit58 < 0) {
				throw new RuntimeException("Not a Base58 input: " + input);
			}

			input58[i] = (byte) digit58;
		}


		int zeroCount = 0;
		while (zeroCount < input58.length && input58[zeroCount] == 0) {
			++zeroCount;
		}


		byte[] temp = new byte[input.length()];
		int j = temp.length;

		int startAt = zeroCount;
		while (startAt < input58.length) {
			byte mod = divmod256(input58, startAt);
			if (input58[startAt] == 0) {
				++startAt;
			}

			temp[--j] = mod;
		}


		while (j < temp.length && temp[j] == 0) {
			++j;
		}

		return copyOfRange(temp, j - zeroCount, temp.length);
	}

这个可以进行转换为交易地址。

private String address2Hex(String exchangeAccount) {
return Base58.bytes2HexStr(Base58.decode(exchangeAccount)).substring(0, 42);
}
