Public Key Cryptography, or Asymmetric Cryptography, is a cryptographic system that uses pairs of keys: Public Key and Private Key. It is one of the most important (if not the most important) part of cryptocurrency protocols, and it is used in sev. If you leave/refresh the site or press the 'Generate New Address' button then a new private key will be generated and the previously displayed private key will not be retrievable. Your Bitcoin private key should be kept a secret. Whomever you share the private key with has access to spend all the bitcoins associated with that address.

There are random generated Bitcoin private keys, converted into WIF format and hashed to addresses. After getting Bitcoin address we check the quantity of transactions(Tx) and get its balance.If you see any address with transactions, we will store this address into leak database and will try to notify the owner.
Because this address was usedpreviously, it may be active now.Nobody is supposed to get these Bitcoins.

In last blog post we had seen how bitcoin wallet is generated. In this blog post we will see how we can generate bitcoin wallet using javascript.

The second andthird sections describe how to extract the public key from the generatedprivate key. Openssl generate private key from cer file. The last section describes how to inspect a private key'smetadata.

I'll list few code snippets here, link to full code is given at the end of post.

This blog post is for learning purposes, the code used here is not fit for production systems or generating new addresses, USE AT YOUR OWN RISK

Libraries used: CryptoJS library from Jeff Mott,
BigInteger and Elliptic Curve implementation javascript libraries by Tom Wu.

Code snippet below fetches random data fetchEntropy function to create a private key & then generates bitcoin address formatAddress function.

Next code snippet uses fetch api to get random data from QRNG server, so make sure you run this code in browser supporting fetch api.

used quantum random number generator server,[1] to fetch random data

Code snippet below takes secret key as input, creates a public key using elliptic curves cryptography, then formats public key to make it into a bitcoin address.

steps to get bitcoin address out of public key are already explained in previous blog post[2].
