1. SourceTree accept putty format key file only
2. If your SSH is generated by Git bash, you have to convert it to putty format (.ppk)
   open puttygen.exe -> load private key -> save private key
3. Config SSH in Sourcetree:
   Tools -> Options -> SSH Key

1. https://confluence.atlassian.com/sourcetreekb/trust-a-server-s-host-key-when-no-button-is-available-to-trust-it-788731545.html

1. Create a SSH key (Git bash is recommended):
   https://docs.gitlab.com/ee/ssh/
   
   ssh-keygen -o -t rsa -b 4096 -C "email@example.com" //Copy public key (id_rsa.pub is default name) cat ~/.ssh/id_rsa.pub | clip

   1 2 3 4

   ssh-keygen -o -t rsa -b 4096 -C "email@example.com"   //Copy public key (id_rsa.pub is default name) cat ~/.ssh/id_rsa.pub | clip

2. Login Gitlab and paste SSH key in account page

3. Execute clone command:
   
   git clone ssh://git@gitlabhost.com:group/repo.git myfoldername

   1	git clone ssh://git@gitlabhost.com:group/repo.git myfoldername
