As an anonymous user (no public key stored at github) I try to clone a public repository through the git@...
URL. But it fails:
$ git clone git@github.com:mikehaertl/phpwkhtmltopdf.git
Cloning into 'phpwkhtmltopdf'...
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
So does this mean, github does not allow anonymous access through the SSH protocol? If so, is this documented somewhere?
