The previous video explained private and public keys in asymmetric cryptography.
Where asymmetric cryptography is a type of cryptography that uses different key pairs for encryption and description of information, you know!
But what’s the difference between the private key and the public key?
The private key is the key used to describe the information encrypted with the public key. In addition, private keys can also be used to create digital signatures.
The private key must be properly guarded, and only the owner can access it. Because if other people know and access the private key, the information stored can be opened, you know!
Meanwhile, the public key is a key that can be used to encrypt information and is used to verify digital signatures.
Unlike the private key, which must be kept secret, the public key can be shared and used by anyone to encrypt information, which will be sent to the owner of the private key.
Only the private key owner can decrypt the information encrypted with the public key. This also ensures that only the private key owner can access this information.
Differences between private keys and public keys:
- The private key is used to describe and create digital signatures, while the public key is used to encrypt and verify digital signatures.
- The private key must be kept confidential, while the public key may be shared widely.
- The private key is used to access information encrypted with the public key, while the public key is used to provide access to other people to encrypt data sent to the owner of the private key.
- The private key must be uniquely generated and cannot be used by others, while many people may use the public key.
Private and public keys are also used in crypto assets, smart contracts, and encrypted communications.
Private keys in crypto assets help sign transactions and provide proof of asset ownership, while public keys are used to verify transactions and identify asset owners.
In general, private and public keys are essential in asymmetric cryptography, which maintains information security.
Correct and safe private and public keys are essential to note to guarantee the security of encrypted information.
