cat id_rsa.pub
Inside the red box is the SSH public key

If you have this file but need a new one, please continue to step 3;
if you do not have this file, please skip step 3 and continue to step 4.
3. Delete the old public key
Enter the following commands in sequence to delete the old public key:
mkdir key_backup
cp id_rsa* key_backup
rm id_rsa*
4. Generate public key
Enter the following command to generate the public key:
ssh-keygen -t rsa -C “你的邮箱”
Replace your email address with the above position. After entering the command, there will be several prompts to set a password. If you do not need to set a password, just press the Enter key until the end. If you need to set a password, please enter the password as prompted. (If you set a password, some git operations in the future will require a password, such as submitting code) After completing the generation of the public key, you can refer to step 2 to view the generated public key.
