Multiple public keys for one private key

If you want to use asymmetric cryptography, you cannot have multiple private key and one public key. These keys work as a pair of key. What is encrypted using the public key can only be decrypted by the private key and this key only. So, No a private key can't have multiple public keys.

Can 1 private key have multiple public keys?

In public key cryptography, every public key matches to only one private key. Together, they are used to encrypt and decrypt messages. If you encode a message using a person's public key, they can only decode it using their matching private key.

Can one private key have multiple public keys Bitcoin?

No. That's the whole purpose of Public-Key Cryptography, it relies on one-way functions, which are mathematical operations that are easy to do in one way, but [almost] impossible to do the other way. An example of a one-way function is prime multiplication, the reverse of which would be factorization.

Can a certificate have multiple public keys?

There is only one private and one public key per certificate. Having multiple public keys for a certificate does not make sense. Assuming you are talking about an X. 509 certificate, read RFC 5280 Section 4 for a breakdown of its internals.

How many public keys per private key Bitcoin?

In Bitcoin, the private and public keys are 256-bit numbers which makes a complete number of conceivable private and public keys of 2^256.

Can one private key have multiple addresses?

You cannot create multiple addresses from a private key, because each private key corresponds one public key.

What is MultiSig public key?

A MultiSig wallet uses more than one private key to authorize crypto transactions. They can also be configured to allow each in the set of private keys to generate a signature. Holding private keys in different locations enhances security, while allowing multiple keys to sign a transaction improves usability.

How many public keys can a private key have?

While you can generate a public key with a private key, doing the opposite is practically impossible because of the one-way “trapdoor” function. You can have any number of public keys connected to a private key.

Can I use same private key on multiple wallets?

there can't be multiple wallets from the same private key, you got something wrong. if the contracts of the tokens you are going to send support BatchSend method, this is the one you have to use to save gas. Otherwise, every new transaction will use 20,000 gasd units, thats the overhead for sending the tx.

How many public keys are possible?

In a public key system, two keys are used, one for encrypting and one for decrypting. The two keys are mathematically related to each other but knowing one key does not divulge the other key. The two keys are called the “public key” and the “private key” of the user.

Can public key be duplicated?

In addition, without a private key, users cannot create their own public key duplicates prior to resending via FTP or SMTP.

Can public key be forged?

The concept of trusting this public key is based on basing your inherent trust in authority which signs this certificate. Signatures are mathematically verifiable so they cannot be forged unless there's an issue with implementation or mathematical algorithm itself.

Can you use the same public key twice?

Yes, that's perfectly legitimate. ssh keys don't care where they were generated, and it's fine to have them on multiple machines at once. Try giving the ssh client the "-v" or "-vv" option (for verbose output) and check the server's ssh log to debug the problem. Save this answer.

How many keys exist in a public private key pair?

There are 2 keys that exist in the public and private key pair. The public key is known to every user and comes into play to encrypt the message while the private key is owned by the owner and no other user knows it and it comes into play to decrypt the received encrypted message.

How many public keys are possible?

In a public key system, two keys are used, one for encrypting and one for decrypting. The two keys are mathematically related to each other but knowing one key does not divulge the other key. The two keys are called the “public key” and the “private key” of the user.

Is it OK to have multiple SSH keys?

As far as security is concerned, you don't compromise your key in any way by using it to log in on a machine (as you would by using a password), so having separate keys for separate destinations doesn't make you any more safe from an authentication/security perspective.

Can public key be generated from private key?

Public keys are created using an asymmetric algorithm, which pairs the public key with an associated private key. The most common algorithms used to generate public keys are Rivest-Shamir-Adleman, elliptic curve cryptography and Digital Signature Algorithm.

Are public private key pairs unique?

Public and Private keys are a pair of unique codes used to encrypt data sent another computer.

How do public and private keys work together?

Public keys and private keys are the working parts of Public-key cryptography. Together, they encrypt and decrypt data that resides or moves in a network. The public key is truly public and can be shared widely while the private key should be known only to the owner.
