Convert Bitcoin addresses to a normal form using BASE58 encoding
In the cryptocurrency, it is not uncommon to read the Bitcoin tiitle in a format. One of thees formats is Base58 encoding, used by the Bitcoinj, a poplar Java library for cooperative wth Bitcoin. The purpose of this article is an examplee to a convert the Bitcoin address for the name for the form (1 … bitcoin) to the usual 20-charact.
The problem:
A typical bitcoin title looks in the “1 … bitcoinj” format:
1j7mdg5rbqyuhenydx39wwk7fslpeoxzy
As you can see, the first 4 characers (1) is a prefix that indicains that a bitcoin. It is still unclear whether or not it is a valid bitcoin.
The solution:
To convert the Bitcoin address, you must the Base58 coded format, Base58.encode () “provid by Bitcoinj. Here’s an example of do do of do.
`Java
import com.google.bitcoinj.address.address;
import com.google.bitcoinj.address.bitcoinaddress;
пublic class main {
Public static vid (string [] args) threws exceptions {
// Create a new bitcoin address from the name format (1 ... bitcoinj)
Title Bitcoinaddress = New Bitcoinaddress ("1J7MDG5RBQYUNYDX39WVK7FSLPEOXZY");
// convert bitcoin to BASE58 coded format
String base58encodaddress = bitcoinaddress.Tobase58 ();
// print out the result
System.out.println (base58encodaddress);
}
}
Howes it is:
The method of tobase58 () A Bitcoinaddress' takes The method Base58.encode () is called on this’ Bytearray’. .
Note that output depends on the Bitcoinj of the version and the conversion process. Usually, weller, that share of a good staring point to convert the titles to a standard form.
Tips and variations:
- If you are a a Java directory soach as Bitcoinj, this to the check to your documentation todate the varous headings.
- Consider adding an error check to verify that the input address is an actually valid Bitcoin YID (Jedid) beefore traying to Code.
- Keep in mind that Base58 coded titles may be subject to certain’s restructions and lives if you use With certai bitcoins or services.
By following theese, you must be able to successfuully convert Bitcoin came to Standard Base58 encoded. Happy coding!
