Understand Ethereum’s public/private keys: a guide for public key differences
When it comes to ensuring transactions in the Ethereum Network, it is crucial to understand the differences between the public/private public keys. In this article, we will discuss the distinctions between these two types of keys and give instructions to when to use.
Master Public Key (MPK): What is it?
A public key to the teacher is a combination of public-private key, which serves as the main detection of an Ethereum card bag. It is used to encrypt data and authenticate transactions to guarantee its integrity and authenticity. A public master code consists of two parts:
- Public key : The public part of the MPK is used to sign transactions in the block chain. If a transaction is sent from one account to another, the sender uses its private key to derive the corresponding public key. This public key can be used to verify the authenticity and integrity of the transaction.
- Private key : The private part of the MPK is used to decipher data stored in the pocket of the Ethereum letter. A private key is a secret code that unlocks the corresponding encrypted data.
Public/private key differences
The main objective of the main differences between the public teacher and the public key:
- Aim:
+ Public key: signal transactions, authentic transactions.
+ Private key: deciphering data stored in the wallet.
* Key size:
The number of bytes used to represent a private key is usually much larger than the public part (for example, 256 bits compared to 65-128 bits).
* Security: A private key is seen as a safer key than a public key because it contains confidential information that must be kept confidential.
Private Key Teacher compared to private keys
A private master key is similar to a public key because it serves as the main identifier for a pocket of Ethereum letters. In contrast to a public key with which transactions and authentication, a private master code cannot be used directly to derive a public key (although it is generated together with the corresponding public master key).
Should I use the Master Public Key (MPK) when generating the public address or key?
If you generate an address in Ethereum, you must use a private key
, not a public master key. Private keys are required to unlock the encrypted data stored in the wallet and create the corresponding public key for the transaction firm.
In summary:
- The teacher’s public key is used to encrypt and authenticate transactions (signature and verification).
- Private buttons are used to decipher data in the wallet (free sharp and creation of public keys).
When generating an address, use your private key to block the encrypted data. Use your private key when creating a transaction to sign it. You can only deliver the corresponding public key from your private key.

Understanding the differences between the master public keys and the public key is of essential importance to ensure its pocket of Ethereum letters. By using your private key to generate addresses and transactions, you can guarantee the integrity and authenticity of your data in the block chain.
