Private Key:

privateKey = bsv.PrivateKey.fromRandom();

• privateKey.toString();

Public Key:

publicKey = bsv.PublicKey.fromRandom(privateKey);

• publicKey.toString();

Address:

address = bsv.Address.fromPublicKey(publicKey);

• address.toString();

AES Encryption (Advanced Encryption Standard)

ciphertext = CryptoJS.AES.encrypt(privateKey.toString(), password).toString();

• Encrypted Key: cypertext.toString()

bytes  = CryptoJS.AES.decrypt(ciphertext, password);

originalText = bytes.toString(CryptoJS.enc.Utf8);

• Decrypted Key: originalText.toString()

Bitcoin Address Insights:

Create QR Code:

var addressCode = 'bitcoinsv:' + address;

new QRCode(document.getElementById("qrcode"), addressCode);

WhatsOnChain API:

    var config = {
        method: 'get',
        url: "https://api.whatsonchain.com/v1/bsv/main/exchangerate",
    };

Wallet with Balance:

    var config = {
        method: 'get',
        url: "https://api.whatsonchain.com/v1/bsv/main/address/" + address + "/balance",
    };
    

Hierarchial Deterministic Keys(HDKs) :

• randomly generate a HD private key
• get the corresponding HD public key
• derive regular private and public keys from a HD key pair

HD Private Keys :

hdPrivateKey = bsv.HDPrivateKey.fromRandom();

• hdPrivateKey.toString();

HD Public Keys :

hdPublicKey = bsv.HDPublicKey(hdPrivateKey);

• hdPublicKey.toString();

Regular Key Pairs from HD Keys :

publicKey1 = hdPublicKey.publicKey.toString();

privateKey1 = hdPrivateKey.privateKey.toString();

Get an address from xprv:

    var hdPrivateKey = bsv.HDPrivateKey.fromString("{xprvkey}")
    
    var privateKeyStandard = hdPrivateKey.deriveChild("m/44'/0'/0'");
    
    var hdPublicKey = bsv.HDPublicKey.fromHDPrivateKey(privateKeyStandard);
    
    var publicKey = hdPublicKey.publicKey;
    
    var address = bsv.Address.fromPublicKey(publicKey);

Mnemonic Phrase:

• A Mnemonic Phrase, otherwise known as a bitcoin seed phrase.
• It is a list of words which store all the information needed to recover access to a bitcoin wallet.

var Mnemonic = window.bsvMnemonic;

var Mnemonic1 = Mnemonic.fromRandom();
