Public key is the address to the wallet that you put out there to receive funds to your account, your private keys is what you use to access your wallet on the blockchain it should be kept in a secure place at all times. Thanks for this explanation, but both of them are important to the wallet, because I think you will be hacked if you lost them or someone stole them from you, they are the key to your wallet, and the key to recover your wallet if you lost password or something else.
Private keys are the keys that unlock your wallet, they must be kept is a secure location cause if loss or stolen you will lose all access to your wallet and public keys are addresses that identify your wallet people can use it to send money to you. Thank you for sharing about this information. I was a little bit confused about the private key and a public key but from your post, I know about it properly.
Thanks for giving this information that I was not knowing best post but do it regularly that every one should learn new new things in the crypto world and I also know there are many that have to know more. On my opinion is that private key is your wallet access key. We need always keep it safe.
And public key is your wallet address. You will receive crypto through your public key. Well the simple private key is a type of key or security code or password that tend to be private and cant is easily accessed or more like strict than the public keys, and yes public keys are more like a path or address and the private key is the key to open a certain path. First of all thank you for your information about the difference between private key and a public key this is very sure that will help many members here to understand more about, but both are important both need to be protected.
Now the terms were more confusing. It really suggest that we should always be careful and let our private keys safe. This information is really important especially there are many sites asking keys. The difference between private and public keys is clearly very different. The private key is only known by us and it is private and the public key is the key that is known by people because it is overall. I agree to you post. But thanks your post is meant full to me and I learned this.
The private key is what you used to access your wallet and public key is used for receiving money. The main difference between the private and the public key is very simple the private key is a private account and the public key is for all the people.
What is public is a key that others can see and use to share coins with us. But what is private is a key that only you are aware of. If others know that you will lose your coins. I think private key and public key are both importent to our account Thanks bro post for the intresting and knowledge information to us now public key we use any website to access your account and private key we operate our main account to send are receive coins when we loss private key are password we never access our account and we loss all our coins where we store in wallet like this 4 million bitcoin loss this method and never recover this coins so think how important this keys so we store in secure place.
You Play - We Pay. Free BTC Satoshi every day. Just like your email password, the private key needs to be kept absolutely secret at all times or you will likely lose all of the wealth in your crypto wallet. I suggest all the users to avoid to share any friend and dont trust on any unknown user that is taking your wallet private key i think that sharing your public key is not a problem.

Ummita Migo Jokeer Posted January 27, Satishmolankar Amirul Islam Posted January 28, Jesoy Mcd0d0 Posted January 29, Afrizal rahman Saira Тут и в предстоящем мы будем разглядывать некую эллиптическую кривую.
Пусть есть две точки. Их суммой именуется точка , которая в простом случае определяется последующим образом: проведем прямую через и — она пересечет кривую в единственной точке, назовем ее. Поменяв координату точки на противоположную по знаку, мы получим точку , которую и будем именовать суммой и , то есть. Считаю нужным отметить, что мы конкретно вводим такую операцию сложения — ежели вы будете ложить точки в обычном осознании, то есть складывая надлежащие координаты, то получите совершенно другую точку , которая, быстрее всего, не имеет ничего общего с либо и вообщем не лежит на кривой.
Самые сообразительные уже задались вопросцем — а что будет, ежели к примеру провести прямую через две точки, имеющие координаты вида и , то есть ровная, проходящая через их, будет параллельна оси ординат 3-ий кадр на картинке ниже. Нетрудно узреть, что в этом случае отсутствует третье пересечение с кривой , которое мы называли. Для того, чтоб избежать этого казуса, введем так именуемую точку в бесконечности point of infinity , обозначаемую традиционно либо просто , как на картинке.
И будем говорить, что в случае отсутствия пересечения. Особенный энтузиазм для нас представляет вариант, когда мы желаем сложить точку саму с собой 2 кадр, точка. В этом случае просто проведем касательную к точке и отразим полученную точку пересечения относительно.
Сейчас, легким движением руки, можно ввести операцию умножения точки на какое-то число. В итоге получим новейшую точку , то есть раз. С картинкой все обязано стать вообщем понятно: Elliptic curve over a finite field В ECC употребляется точно таковая же кривая, лишь рассматриваемая над неким конечным полем — обычное число. То есть.

In simple words, it can be described in the following way:. He knows her public key and uses it to encrypt the transaction. Jane should be the only person who can authorize the transaction as nobody else knows her private key. When it comes to cryptocurrency, a private key is what you own physically.
It proves your rights to manage your digital assets and to authorize any transactions. Whoever knows this key can spend the associated funds. Though both types of encryption cater a similar purpose, they differ in many ways. In public-key encryption, there must be two separate keys for encryption and decryption. The private key is for the owner only, while the public key is available to anyone.
One key is required for transmission between the two parties involved in symmetric key cryptography. The same private key is used both to encrypt and decrypt the information. It is shared between the sender and receiver of an encrypted message. The private key mechanism is much faster than the public key.
Once lost, the private key is impossible to restore, and the encrypted file becomes unusable. Typically, these keys are difficult to remember as it involves complex numberings. Still, the safety of private keys is entirely up to its owner.
That is why the best method to keep your private keys safe is an offline storage device. On the other hand, the public key is open to all users and should be available upon search. It is unlikely to lose the public key. That makes it easy to identify the message sender in the network and confirm that a trusted identity sent a message. That is the only way to convert the message back.
Public key cryptography is used in a large number of protocols and data formats, which are implemented by a vast range of applications and system software. It is widely applied to software programs, such as browsers, to ensure secure connections in insecure networks. Asymmetric cryptography forms the base for the blockchain algorithm, which constitutes a base for all cryptocurrencies.
There is no perfection for any methodologies or encryption, and that includes the public and private keys. Here are the pros and cons:. Adopting private key encryption technology is an excellent way for any business to protect important information from prying eyes. Regardless if you choose a symmetric or asymmetric encryption method. They both have their advantages and disadvantages as any other technology. However, symmetric encryption is faster and easier to carry out.
The system performs a single, reversible mathematical equation to encrypt or decrypt a file. That is why this method requires fewer computer resources than asymmetric encryption. Simultaneously, while private key encryption provides a much higher security level, it still has some setbacks.
The main problem associated with this method is the problem of key transportation. It involves insecure forms of communication to transmit the key. This method cannot guarantee the origin and authenticity of the message and may cause some problems if there is a dispute or doubt. If a user wants to segregate the data or funds among groups, it is necessary to generate and manage multiple private keys. Too many keys are not so convenient, and a new shared key with every different party may result in increased insecurity.
The disadvantages of this method are associated with some severe weaknesses. First, the loss of the private key should lead to dismal consequences. That means that no one can ever decrypt the received data. In terms of cryptocurrency, the wallet owner will not be able to get access to his or her wallet if the private key is lost. The choice of the encryption method varies depending on your preference and convenience. Symmetric encryption is beneficial if you value speed and data protection over the rest.
For example, the Advanced Encryption Standard AES adopted symmetric encryption algorithm is used by many big companies and entities like Apple and Microsoft. Besides, if you focus on data storage, symmetric encryption is ideal.
It works well if the encrypted data is stored on a device and that data is not being transferred. Asymmetric cryptography will be your preferred choice if increased security is the priority over speed and computing power. Blockchain technologies rely on identity confirmations to authorize transactions.
Thus, crypto traders and investors would prefer this. As we move towards the digitized sphere, data storage and security have increasingly become important. Public key encryption helps users maintain reasonable security practices as nobody knows the private key paired with the open public key. It is advantageous when to avoid potential interceptions and cyber frauds. However, all you need is to ensure your private key secure and inaccessible to others.
To start trading is hard, but securing your funds is even more challenging. Bybit urges you to secure your data and learn about the importance of respecting privacy, safeguarding data, and enabling trust. Sign Up. Sign in. Forgot your password?

It is a crucial aspe Cryptography Methods Used in Cryptocurrencies When it comes to cryptography in cryptocurrency , there are several methods, and that includes symmetric encryption, asymmetric encryption, and hashing. Symmetric Encryption It is one of the most popular, easiest, yet effective encryption. Asymmetric Encryption Unlike symmetric, the encryption and decryption of messages usually involve two keys— Private and Public Key. The sender uses this key to encrypt information.
The sender sends the encrypted information to an addressee. The addressee uses his or her private key to decrypt the data. Performance The private key mechanism is much faster than the public key. The digital signature provides certain security benefits such as: Authentication. It proves if the message or user is legal or not as forging is impossible. The message sender cannot deny the signature after communication.
The signature serves as a guarantee that the received message is not altered. This is to inclusive in binary. Then the private key can be 24 groups of decimal numbers, each number 0 to Much easier to write, but still error prone. The solution to this error risk problem was BIP This is a protocol that suggests we all use a list of protocol-defined words, and I suspect they were chosen in such a way that one word is unlikely to be misread as another word.
This list contains words, in alphabetical order. Go look at the list. Each is given a number from 0 to This way, each decimal number in the private key can be written down as a word. There is nothing special about a word that it should have a particular number. This is where seed words come from. When you enter a seed word phrase in a software wallet, it converts the words into 11 digit binaries, and then pastes them all together in order to produce a giant digit binary number, the private key The last word contains some checksum digits and are not random, remmeber?
For a 12 word seed the private key is half as long, bits. It is unfortunate that the original source of BIP 39 words, which is stored in GitHub, is numbered from 1 to , instead of 0 to This is just the Github formatting not an intentional design. This is wrong. The binary of 1 is , and this is not what we want. Because of this formatting, ALL words therefore are labelled 1 higher than the number they encode. We might produce a binary from coin tosses, and a computer can help us to get the last 8 digits shown in italics:.
Then we look up the words in a table:. Well, this list is from Github, so the words are labelled from 1 onwards. So every number is too high by 1. So we have to subtract 1 to find the word we want. So word , dumb, actually represents , the number we want. Notice how the words that start with a letter lower in the alphabet represent a smaller number, and the words higher in the alphabet represent a higher number.
This is obvious only after you appreciate how the words are ordered and why. Note how adding a passphrase completely changes the downstream extended private key. Modifying the derivation path also changes the downstream data. The diagram shows that this Key produces many individual private keys non-extended, just regular private keys and each one produces a regular individual public key which produces a single address.
Each individual private key can not reveal the extended private key. It might be possible though, that an individual private key might reveal the next private key in the list, again, not sure. Definitely though, each public key can not reveal the individual private key, or any private key for that matter. That is important to know. This means legacy addresses will be created.
Legacy addresses are also called P2PKH, pay to public key hash. These addresses are also called P2SH, Pay to script hash. They start with bc1q. Finally, keys that start with upper case X, Y, or Z, produce addresses for multisignature wallets. The purpose of the extended public key is not immediately obvious. The wallet will look identical. A wallet created with the public key can not spend.
Bitcoin and every other public blockchain face a central challenge. While the blockchain is a publicly accessible peer-to-peer network whose code is open source, property rights must be stored digitally unalterable and tamper-proof. The property must only be able to be assigned exclusively to one person, without others having access to it.
This must be realized without affecting the decentralized architecture of the network. This is where cryptography comes in. The basic idea behind cryptography is to protect data from unauthorized access through encryption. The term comes from cryptology and encompasses a science that develops methods and algorithms to encrypt data. Only the authorized person should be able to access the data by decryption and encrypt the data again by encryption.
Basically, a distinction can be made between symmetrical and asymmetrical cryptographic procedures. The same digital key is used for encryption and decryption in the symmetrical procedures. Both the sender and the receiver use the same key in the example: black to encrypt the encrypted message red. However, this procedure is completely unsuitable for cryptocurrencies, since only one person is supposed to own Bitcoin or another cryptocurrency.
A key that must be shared between several people is contrary to the principle of property. Because of that reason Bitcoin uses asymmetric cryptography. It uses a key pair consisting of a public key and a private key, which is why it is also called public-private-key cryptography. In contrast to symmetric cryptography, there are two keys where the public key can be freely disclosed and the private key is a secret.
The encrypted data can only be decrypted with the private key. As the following graphic shows, the message is encrypted with the black key and decrypted with the yellow key Private key. Both the sender and the recipient each have a public and a private key to encrypt and decrypt the different encrypted message.
The basis of asymmetric cryptography is a mathematical algorithm by means of which the public and private keys are generated and thus linked. Due to this mathematical connection, information encrypted with a public key can only be decrypted with the corresponding private key. It is important to know at this point that the mathematical functions used here are practically irreversible.
This means that they can be calculated in one direction, but not in the other. In terms of cryptocurrencies, this means that a public key can be derived from the private key, but never the other way around. Otherwise anyone could derive the private key from a public key.
The process can be explained as follows using an example. After receipt, the sender can encrypt his data with the public key of the receiver and send the data. Then only the owner of the private key can decrypt the data. Routinely, very few Bitcoin users come into contact with the private or public key. In most cases, Bitcoin Private keys are stored in the Wallet file and managed by the Bitcoin Wallet software.
The Bitcoin address is the only representation of the public key in the form of a hash function that the user routinely sees. The fact that the user usually does not come into contact with the asymmetric key pair is to be welcomed from the point of view of user-friendliness. However, the lack of visibility does not mean that the key pair is not needed at all or only rarely.
This is not the case. The private key and Public key are required whenever a transaction is to be sent. While the Bitcoin public key is used to receive Bitcoin, the Private key is used to sign Bitcoin transactions. A bitcoin public key is another large number but allows bitcoin to be locked and received.
People can over-complicate explanations by trying to explain digital signatures, signing transactions, and wallet import formats. These two keys or numbers are related mathematically on the secpk1 elliptic curve.
The private key is a randomly generated number plotted on the curve, and the corresponding public key is a related point on that curve. The real point of this magical curve is that it creates trap door functionality , meaning that once we generate the first point on the curve the private key the corresponding second point public key is easily found but impossible to find in the opposite direction.
Because public kets come in different formats they can start with a 1 , 3 or bc1. There are uncompressed public keys, compressed public keys, and wif format. The private is generated from a part of the software that is specially designed to be able to handle big numbers and generate them at random. TIP: To get a more hands-on understanding of this you can play around with bitaddress.
There a lot, about 10 million million million million million million million million, or possible private keys to be exact. The number of possible keys is so large, that security of bitcoin relies on the assumption that no one will ever randomly generate the same two private keys twice. In the same way numbers can be expressed as words zero and numerical digits 0 , keys are just a really long string of numbers that have the same properties.
Instead of using the word expression of the random number, the seed phrase uses a list of 12 or 24 random words to represent the random number. The purpose of the mnemonic is to convert currency, money, and funds into human-readable words.
