With regard to cryptocurrencies like Bitcoin, the concept of keys is fundamental. The public key is used for transactions and the dissemination of new blocks to the network, while the private key is required for transactions and secure withdrawals. However, a question that has long tormented cryptocurrency fans is: How does the public key translate into a private key? Can it be broken without being able to obtain the original bitcoin?
To grasp this concept, let us dive more deeply into the world of cryptographic keys.
public Key Basics
A public key is a unique identifier attributed to an entity (or in this case, a cryptocurrency portfolio) which can be used for encryption and decryption. It is generally represented as a character string in the format "P.Key", where "P" represents the private key. The objective of the public key is to facilitate secure transactions by encrypting data with the corresponding private key.
Private Key Basics
A private key, on the other hand, is a secret code that can only be used for decryption purposes. It is also represented as a chain in the "P.Key" format, but it is generally not posted publicly, because it contains sensitive information on the transactions and financial assets of a person or an entity.
The link between the public key and the private key
Now let's talk about the question to be accomplished: can we get the private key to the public key without compromising security? In theory, yes, it may be possible to break encryption with a determined effort. However, obtaining the original bitcoin of its public key is very unlikely.
The reason lies in the functioning of Bitcoin blockchain:
- Generation of keys : When you create a new Bitcoin portfolio or send bitcoins to someone else, your private key is generated and stored safely on the customer side (i.e. say your device). The public key, however, remains accessible to the public.
- Structure of the Blockchain
: Each blockchain Bitcoin block contains a reference to the hash of the previous block. This creates a chain of transactions that can be used to recover the original blockchain public key.
- Hhasow functions : The blockchain uses advanced cryptographic hash functions (such as SHA-256) to create and check the blocks, which makes it extremely difficult to modify or modify data without compromising security.
Break the code
To understand why the rupture of the code is so difficult, let's examine how a potential attacker could try to recover your private key:
- Onderne Engineering : An attacker could try to analyze the public key and identify the models or weaknesses that could be used to break the encryption.
- Attacks of the hash function : A sophisticated attacker could try to use brute force methods or lateral channel attacks on the hash functions used in Bitcoin blockchain.
Although it is theoretically possible for an attacker to obtain a private key to the public key, the probability of success depends on various factors:
* Effort and resources : The quantity of computing power required to break the code will depend on the attacker method chosen.
* Properties of the hatching function : The specific hash functions used in the Bitcoin blockchain can offer a degree of security, which makes it more difficult for an attacker to break the encryption successfully.
Conclusion
In summary, although it is theoretically possible to obtain your private key from the public key without compromising the security, efforts and resources necessary make it extremely difficult. In addition, the operation of the Bitcoin blockchain ensures that the attempt to break the code will be very unlikely.
For the moment, it seems that the maintenance of your private key is a better practice when using cryptocurrencies like Bitcoin.
