TortoiseSVN is supporting SSH authentication via Putty’s Pageant. Thus:
- Start Pageant
- Add key (.ppk file, e. g. generated from OpenSSH key)
- (Minimize Pageant)
- Start TortoiseSVN, e. g. Repo-browser
- Type in URL, e. g.
svn+ssh://user@server/path/to/svn. Important: set user in URL (user@) - Connection should work
