Although this is an old vulnerability, it still exists. Although few bitcoin companies/wallets will reuse values when signing transactions these days, persons who are producing new copies of old currencies and wallets are often unaware of this flaw. Looking for how to crack blockchain private key?, you are at the right spot.
During our investigation, we learned that a large number of Russian bitcoin hackers have created bots that automatically steal funds from susceptible addresses of this type and others, such as those stated at the start of this tutorial.
Before we begin, we’d like to point out that we’ve received an overwhelming number of requests for regaining access to bitcoins/wallets stolen by hackers or scammers, to the point where we don’t have an infinite amount of time to assist everyone, but we’ll do our best to assist as many people as possible.

We have a Bitcoin-specific section where you can post your questions or anything else you want to discuss. The blogs of https://decryptkey.com/blog/ are updated on a regular basis (blog: Hack Bitcoin Private Key). Check it out if you want to learn more. Hence you may generate private key and recover non-spendable funds in blockchain.
Here are a few ways a bitcoin address or wallet could be compromised.
A popular password, such as “123456,” is used to establish a private key. It was a simple copy/paste error. Non-standard outputs are used to create a transaction. A random number generator was either utilised incorrectly or gave identical results. The private key was made available to the public.
We’ll be discussing a transaction involving a faulty random number generator (string). Due to a lack of knowledge, programming flaws, or a malfunctioning random number generator, certain addresses re-use specific values in a transaction.
Consider the following transaction: https://www.blockchain.com/btc/tx/9ec4bc49e828d924af1d1029cacf709431abbde46d59554b62bc270e3b29c4b1?ref=decryptkey.com
This script has two inputs and a single output. It’s all right. Inputs are pointers to prior transaction outputs. At its most basic level, outputs are an amount and an address.
When we examine the inputs of these scripts more closely, we see that they are very similar.
ScriptSig: PUSHDATA(71)[30440220d47ce4c025c35ec440bc81d99834a624875161a26bf56ef7fdc0f5d52f843ad1022044e1ff2dfd8102cf7a47c21d5c9fd5701610d04953c6836596b4fe9dd2f53e3e01] PUSHDATA(65)[04dbd0c61532279cf72981c3584fc32216e0127699635c2789f549e0730c059b81ae133016a69c21e23f1859a95f06d52b7bf149a8f2fe4e8535c8a829b449c5ff]

The signatures (specified as ‘r’ and ‘s’) appear at the start of the scripts. The hex public key is at the end of the script.
As a result, we have:
r1: d47ce4c025c35ec440bc81d99834a624875161a26bf56ef7fdc0f5d52f843ad1r2: d47ce4c025c35ec440bc81d99834a624875161a26bf56ef7fdc0f5d52f843ad1 s1: 44e1ff2dfd8102cf7a47c21d5c9fd5701610d04953c6836596b4fe9dd2f53e3es2: 9a5f1c75e461d7ceb1cf3cab9013eb2dc85b6d0da8c3c6e27e3a5a5b3faa5bab
The r values in the scripts are, it turns out, identical. As a result, we may deduce the private key.
Let’s look at some math problems:
Bitcoin Private Key = (z1*s2 – z2*s1)/(r*(s1-s2))
We now need to find the z1 and z2 values, as well as the r and s values.
Further the values z1 and z2 can be found from the products developed for you at https://decryptkey.com/shop , and hence the private key can be generated by hacking the private key.
