ssh-keygen -t rsa -b 4096 

(-b 4096 rsa secret key generated to represent a length of 4096 bit) input after the instruction, let us specify the secret key to generate a file directory, can skip directly enter generated directory c:\user\WINDSUN\.sshgenerated under this directory : id-rsaand id-rsa.pubthe two documents, the first one is the private key file, the second is the public key file, the user name is your computer user name

Problems encountered

If the message pipeline error, the problem may be

1. ssh to your Linux server is configured with the question of whether to solve the problem by modifying the configuration of the test.
2. Delete ".vscode-server" directory created on the server. This is a hidden directory created in your home directory (you can use the "ls -la" show all files I believe). Probably some incorrect data is cached in there, so delete the directory will make your situation more clean. After deleting, you can try to reconnect via remote-ssh on vscode.
3. Problems encountered different operating system versions may also be different.
