This article will explain in detail whether the Cloud Virtual Machine supports tls service. The content of the article is of high quality, so I will share it with you for reference. I hope you will have a certain understanding of relevant knowledge after reading this article.

Yes, you can view tls related help documents in the management background of Alibaba Cloud Virtual Machine. Upgrading TLS version of Cloud Virtual Machine requires modifying registry and system group policy.

What is TLS?

The Secure Transport Layer Protocol (TLS) is used to provide privacy and data integrity between two communicating applications. TLS records are used to encapsulate various higher-level protocols. One such encapsulation protocol, the handshake protocol, allows the server and client to authenticate each other, negotiating encryption algorithms and encryption keys, before the application protocol transmits and receives its first data byte. The protocol consists of two layers: TLS record protocol and TLS handshake protocol.

Functions of TLS

1. Encrypting transmitted data over the Internet to prevent theft.

2. Maintain data integrity on the way from endpoint A to endpoint B.

3. The encrypted data in SSL Certificates are transmitted to the server, and the server uses the private key to decrypt to prove its identity.

Modify System Group Policy

1. Click Start-> Enter gpedit.msc;

2. Expand Computer Configuration-> Manage Templates- > Network and select SSL Configuration Settings;

3. Double-click SSL cipher suite order and check enabled, copy content from SSL cipher suite and paste it into Notepad;

4. Move the following to the beginning of the document

TLS_RSA_WITH_AES_256_CBC_SHA256，TLS_RSA_WITH_AES_256_CBC_SHA;

5. Copy the above cipher suite and paste it into the SSL cipher suite box in Group Policy, then click OK; restart the server for the changes to take effect.

About whether the Cloud Virtual Machine supports tls service, I hope the above content can help you to some extent and learn more knowledge. If you think the article is good, you can share it so that more people can see it.
