Rationale: typing your password again and again is boring, but saving it cleartext is insecure

1. download and install TortoiseSVN
   • use 64 bit version if your Windows is 64 bit
2. create a key pair
   • one key pair per user per client machine is fine
   • use PuTTYgen from PuTTY, no install necessary
   • SSH-2 RSA is fine
   • 2048 bit
   • click generate and provide some randomness
   • change Key comment to identify key later (e.g., on the svn server)
   • save private as *.ppk file and note its location
   • copy the complete textfield to a text editor and save it as *.pub file in the same location (for future reference)
3. append the *.pub file to ~/.ssh/authorized_keys on the svn server
   • SSH Login to the SVN Server with Password
   • either open the file in an editor and copy/paste the content of the *.pub file
   • or upload the *.pub file with WinSCP and save it as authorized_keys (if this file already exists you have to append its content)
   • type public_id | plink.exe -pw username@hostname “umask 077; test -d .ssh || mkdir .ssh ; cat » .ssh/authorized_keys” might also work Source
   • take care that ~./ssh is in mode 700 and its files in mode 600
4. secure the *.ppk file
   • e.g., NTFS encryption
5. (optionally) test with PuTTY
6. configure TortoiseSVN
   • Settings → Network → SSH client
   • C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe -i complete-path-to-file.ppk -l rind
7. configure Eclipse
   • setup environment variable
     • Computer → Properties → Advanced → Environment Variables
     • SVN_SSH
     • C:\\Program Files\\TortoiseSVN\\bin\\TortoisePlink.exe -i complete-path-to-file.ppk -l rind
   • install Subclipse via Eclipse
   • use JavaHL (JNI) as SVN interface

Alternative: use PuTTY Pageant instead of the -i parameter

similiar like in Windows, but TortoiseSVN is not needed

ssh-copy-id makes it easy to append the public key on the server

Eclipse with Subclipse and JavaHL need no extra configuration
