** Referee of signatures without open key
When you send off the subsidies of the Bitcoin with the help of Bitcoin-Qt, one of the general problems is concluded in the volume that it is possible. Critic key. In this state, we are submerged in the function of the Bitcoin-QT signature and the exploration of its functionality.
What is signed in Bitcoin?
In the bitcoins, it is not such a “open key”, as in other cryptographic systems. In addition, this is an algorithmic solidation, a consensus, which is evidenced by the power. The process is included in the precipitation, the hasha of the publication key and signature of the equivalent hash with its own liner key.
How do you sign Bitcoin-QT-SOPTS?
Bitcoin-QT use the ECDSA algorithm (elliptic tingle algorithm signatures) for signatures. This algorithm is widely used in the final cryptography of its efficiency, the scale and the immobility. Here is a high -tenses of that, as it works:
- This process creates an entrance stack, used for the creation of signatures.
- Generation Book : Renovate Generate a pair of cryptographic key, included:
* Putting key (also the existence as a seed or a point of the entrance): this is used for signatures and discovers of identifies.
* Public Key: This is what every one can use the signature of the signature.
Signature Signatures
To make the signature, the deposit is filled with this shagie:
- Hash -Vivod : Recruiter echoes their entrance, use the determinated Hash -function.
- Hash -ot Key : Settiler scares out the open key, use algorithm, used for signatures.

Signature Signature in Bitcoin-Qt
To make it possible that the planned signature of the factual registration of the subscribed without access without access to the open key, using the combination of cryptographic methods of bitcoin-QT:
- Hash -Induction : Opener scratches the signature and runs into the co -consignment with the hash, which in the combined with the hashized entrance and the open key.
- Signature Signature : If the verification passes, the departer can be trusted that the composition was a subscriber’s subscriber.
conclusion
Such an image, the function of the Bitcoin-Qt signatures, the combination of the algorithms hash-algorithms and the cryptographic key to the prevents of the sublime and the intake of the signatures. Creating a couple of key (partly and public) and useful compositions, Bitcoin-Qt provides efficient and renewal method of drizzle and signatures, do not go to the general.
This is especially field in the walls, where the access to the general key is ogranic or the realization. However, it is important to note that it is necessary to be ogriconing for this approach and maybe utmost for all cases of use.
