Here is a complete description of the role of public and private keys in safety and some examples:
Public key
A public key is used to sign the data, which makes it counterfeit. It is like a digital identity card that shows that you have the right to use certain information.
- Use: sign e -mail, documents and other digital files.
- Purpose: guarantee the authenticity and integrity of the data.
- Example: When sending an e -mail with a public key, the recipient can confirm the sender’s identity using their private key to dismantle the encrypted message.
private key
A private key is used for encryption. It is like a secret code that only the owner can disassemble.
- USA: data advice, which makes countless unauthorized parts.
- Purpose: protect sensitive information from access or change without authorization.
- Example: When saving sensitive financial information on your computer, use a private key to encrypt and keep them confidential. Anyone who has access to your device needs both public and private keys to read encrypted information.
CHAIR of Keys
The key pair consists of a public key and a private key. A public key is used for the signature, while the private key is used for encryption.
- Used: sign and -mail with a public key and encrypt sensitive information with a private key.
- Purpose: guarantee safe communication and protect sensitive information.
- Example: To send an and -email signed by a digital certificate, use both the public key (sent via e -mail) and with a private key (maintained on the device).
Keys Management
The management of the keys refers to the process of storage, management and safe distribution of encryption keys.
- Used: Sensitive information such as password and encryption keys in a safe way.
- Purpose: prevent countless access to sensitive information.
- Example: save complex passwords and related secrets (e.g. private key) using the safe management of passwords.
Best Practice
To ensure the safety of the encryption key:
- Keep the keys safely : use the combination of storage solutions based on hardware and software such as encryption algorithms and password management.
- Use strong passwords : select univocal and complex passwords for all accounts and systems that require authentication.
- Keep the Updated Keys
: regularly updates and secretly hide sensitive information to guarantee their security.
- Use protected key exchange protocols : Use well-consolidated protocols such as Diffie-Hellman or Dive-Hellman elliptical curve, changing the encryption keys with others.
By following these best practices and understanding the role of public and private keys safely, you can protect your sensitive information and guarantee the confidentiality and integrity of digital communication.
