Here is an overall outline of the role of the public and private key in safety, as well as some examples:

Public key

A public key is used to sign the data, which makes it false durability. This is like a digital identification card that proves that you have the right to access specific data.

• Use: Signing E -past messages, documents and other digital files.

• Objective: To ensure the authenticity and integrity of the data.

• Example: When sending E -past with the attached public key, the recipient can check the sender’s identity using his private key to decipher the encrypted message.

private key

A private key is used for encryption. It’s like a secret code that can only be deciphered by the owner.

• Use: encryption of data, which makes it unauthorized unauthorized parties.

• Purpose: Protect sensitive information from access or change without permission.

• Example: Sensitive financial information on your computer, use a private key to encrypt data and keep it confidential. Anyone who has access to your device will require both public and private keys to read encrypted data.

Key couple

The main pair consists of public keys and private keys. A public key is used for signature while the private key is used for encryption.

• Use: Sign E -psts with public key and encrypt sensitive private key information.

• Objective: Provide secure communication and protect sensitive data.

• Example: When you want to send an E -past signed by a digital certificate, use both a public key (sent by E -past) and a private key (maintaining your device).

Key management

The main guide refers to the safe process of storing, management and distribution of cryptographic keys.

• Use: Safe storage of sensitive data such as passwords and encryption keys.

• Purpose: Prevent unauthorized access to sensitive information.

• Example: Use a protective password manager to maintain complex passwords and connected secrets (as a private key).

best practice

To ensure the safety of cryptographic keys:

1
Safe Store the keys : Use a combination of hardware and storage software solutions such as encryption algorithms and password managers.

• Use powerful passwords

  

  : Select unique, sophisticated passwords for all accounts and systems that require authentication.

3 ** To ensure their safety, regularly update the keys: Update and calculate your sensitive data regularly.

4
Use key exchange protocols : Use the protocols created, such as Diffie-Hellman or the elliptical Diffie-Hellman curve, exchanging cryptographic keys with others.

By performing this best practice and understanding the role of public and private keys in safety, you can protect your sensitive data and guarantee the confidentiality and integrity of digital communication.
