This article will explain in detail what the CVM key is, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

The key generally refers to the SSH key pair, which is often referred to as the key pair, which is different from the remote login Linux instance authentication method of user name and password.

The SSH key pair generates a pair of keys through the encryption algorithm, which uses RSA 2048-bit encryption by default. One is open to the outside world, called the public key, and the other user keeps it himself, which is called the private key.

Compared to user name and password authentication, SSH key pairs have the following advantages:

1.SSH key is more secure and reliable for login authentication, and it is impossible to derive the private key from the public key.

two。 The security strength of the key pair is much higher than that of the conventional user password, which can put an end to the threat of violent cracking.

3. If the public key is configured in the Linux instance, you can use the private key to log in to the target instance through the SSH command or related tools locally or in another instance without entering a password.

4. Easy to remotely log in to a large number of Linux instances, easy to manage. If you need to maintain multiple Linux instances in batches, it is recommended to log in this way.

In addition, SSH keys only support Linux instances.

So much for sharing what the CVM key is. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
