tortoisesvn: howto use key authentication rather than password?

I have tortoiseSVN set up on my local windows 7 computer. I access the repository with a password. For example, if I right-click on a file from within Windows Explorer, and then select 'repo-browser', the password dialogue box pops up.

I now would like to modify my setup to use key authentication, rather than passwords. I followed the instructions here: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-ssh-create-keys.html

Everything worked fine until I got to this step:

Testing SSH with TortoiseSVN: ... Right click on any folder in Windows Explorer and select TortoiseSVN → Repo-Browser. You will be prompted to enter a URL, so enter one in this form:

svn+ssh://svnuser@SvnConnection/repos

When I select Repo-Browser, the password dialogue pops up immediately. I am not prompted to enter a URL. If I try canceling the password dialogue, the password dialogue just 开发者_如何学Cpops up again.

How do I get the password dialogue to stop popping up? How do I "tell" TortoiseSVN that I want to use key authentication rather than passwords?

The password dialog probably pops up because TorToiseSVN fails to find any ssh key.

On Windows, this is usually due to the environment variable HOME being not defined by default. (HOMEDIR is, HOME is not).

You can set HOME to any directory of your choice, it needs to contain a .ssh directory with your public/private key in it.
Then, make sure that basic SSH communication works first, before fiddling with the TortoiseSVN client itself.
