It is an articulation about how a message with a private key using Bitcoin on Typitscript.
Subscription message with private keys on Bitcoin
In this art, we will show that you use the lived Bitcoinjs library to create a private diet phrase and the use of to sit. We will also demonstrate how to link the private key to the end points of the end points of the Alcressa and the open application vapor.
Step 1: Create a private key
First, you need to create a private phrase from your seed. You can do this by running the follower at your terminal:
`!
CH -L
s
Replace
Step 2: Import Libroys and load the private key
Then we need to import the Bitecoins library and load the top of the private key:
imagine
Import * as 'bicoinjs-lib' bitcore;
impress * as ° of 'Sey-SCP256K1';
CONT PRIVATEKE = Wait Requires ('./ Private_y.Pem');
s
Step 3: Create a message to sign
Create a monthly month. For exam, let's go, we will have an NFT contract address and a recipient address:
imagine
CONCERTEADRESS CONCERT = '0x…'; // Replace with hiring
Consecutive Recientadress = '0x…'; // Replace with the recipient's address
s
* Step 4: Signor of the Messasage
Now we can create a Bitcoinmsage list to install your message and private key:
imagine
BITCOINMESSAGE IN CONSULTATION = REQUIRE ('BITX-LIB'). Bitcoinmessage;
Continent Bancoinmessage = New BitcoinMessage (Acts
CONTRACTIONADRESS,
recipient,
Father: 'Hello, world!'
^)
Consent Signature = Wait Bitcoin.Sign Message (Privatekey, {
Address: Bitcoin Message.address.adres.btc,
Network: love.mym.manecon,
^)
` s
Step 5: Breaker key for end points
Finally, we need to do with private data with the “BCADRESS” end points and occupation ‘terminings’ styling:
imagine
Babics = Requires (‘Bitcoinjs-Lib’);
Consta EC = Requires (‘Tiy-Secp2566k1’);
// defining the terminals
Concert contracts = ‘htps: //example.com/contractor;
Consequently, containmentpoint = ‘
// Create a private complaint phrase file
CONT PRIVATEKE = Wait Requires (‘./ Private_y.Pem’);
// lod the top key
Babies continents = await EC.YKEY FERMPRIVATE (Privatekey);
// binnd the private key to the terminals
Trudpoint rise (privatekey) {
Concert = New BitcoinMessage (Acts
CONTRACTIONADRESS,
Father: ‘Hello, world!’
^)
Consent Signature = Wait Bitcoin.Sign Message (Privatekey, {
Address: Bitcoin Message.address.address.btc,
Network: love.mym.manecon,
^)
Return {concrete, signature};
}
ASCION OF THE CONTRACTING PARTY (PRIVATE (PREDKEY) {
// Create a private complaint phrase file
CONT PRIVATEKE = Wait Requires (‘./ Private_y.Pem’);
Babies continents = await EC.YKEY FERMPRIVATE (Privatekey);
// lod the top key
Babics = Requires (‘Bitcoinjs-Lib’);
// binnd the private key to the contract terminal
Returned new promising ((resolve, rejected) => {
Getedpoint (privateky.the (data) => {
Solve (DAT);
}). Catch ((error) => {
reject (error);
^)
^)
}
ASCULTUS OF THEGETTENGETT OF WARDROBET (PREDKEY) {
// Create a private complaint phrase file
CONT PRIVATEKE = Wait Requires (‘./ Private_y.Pem’);
Babies continents = await EC.YKEY FERMPRIVATE (Privatekey);
// lod the top key
Babics = Requires (‘Bitcoinjs-Lib’);
// binnd the private key to the recipient’s endpoint
Returned new promising ((resolve, rejected) => {
Getedpoint (privateky.the (data) => {
Solve (the concert: data.contracttract, signature: date.SIGNATURE});
}).
