Learn Git to configure SSH (common to github, gitee, and gitlab)

Preface

Git warehouses generally have two reading and writing methods: https and ssh. https is very simple and can be accessed directly through account and password, while ssh uses It is more cumbersome, and you need to configure the public key and private key first, because ssh uses RSA-based encryption for verification.

Recommendation (free): Git

SSH configuration

github and gitee both provide Git based on the SSH protocol Service, before using the SSH protocol to access the warehouse, you need to configure the SSH public key of the account/warehouse.

1. Generate key

You can generate ssh key by following the command:

ssh-Learn Git to configure SSH (common to github, gitee, and gitlab) -t rsa -C "xxxxx@xxxxx.com"  
# Generating public/private rsa key pair...

Follow the prompts and press Enter three times to generate ssh key. Obtain your public key by viewing the contents of the ~/.ssh/id_rsa.pub file

cat ~/.ssh/id_rsa.pub
# ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC6eNtGpNGwstc....

2. Deploy the public key

Copy the generated ssh key, add the generated public key to the warehouse through the warehouse homepage"Management"->"Deployment Public Key Management"->"Add Deployment Public Key".

3. Add ssh trust locally

After adding, enter

ssh -T git@gitee.com

in the Terminal. For first time use, you need to confirm and add the host to this Machine SSH trusted list. If the content Hi XXX! You’ve successfully authenticated, but Gitee.com does not provide shell access. is returned, the addition is successful.

SSH Add Tips

After the addition is successful, you can use the SSH protocol to operate the warehouse.

4. Warehouse public key and deployable public key

In order to facilitate users to use a set of public keys under multiple project warehouses and avoid the tediousness of repeated deployment and management, Code Cloud has launched The "Deployable Public Key" function supports the use of the deployed public key of another warehouse space under the current account name/participation in one warehouse space to achieve public key sharing.

SourceTree settings

Users who use git generally use SourceTree more. After configuring ssh, they need to be imported into sourceTree before they can be used.

1. Create or import ssh key

Click[Tools] -> [Create or import SSH key]
## Open the PuTTY tool generator
Use Generate to directly generate the public key and private key
If you already have the key, you can click Load to load it and select the id_rsa file.

2. Generate ppk file

After loading, do not close, continue to click **[Save Private key]

. Save[ppk file]**, (It is best to put these files together, under the user/.ssh file)
After saving, you can close the window

3. Import the PPK file

and then open **[Enable SSH Assistant]**

After opening, it may be hidden in the task panel below, just find it and open it

Click the **[Add Key]
button and select the ppk file just generated**
The configuration is complete and you can close it
Next, sourceTree can read and write remote warehouses through ssh.
