I am using com.sshtools.j2ssh API for SFTP connections. I can connect using user name & password. But i want to connect thru public & private key.

what is the folder structure to place the public key in SFTP server?

And also How to check the configuration on SFTP server regarding public key?

Hi,

Welcome to JavaRanch!

A bit of business: you may not have read our naming policy on the way in. It requires that you use a full, real (sounding) first and last name for your display name. Initials aren't enough. You can change your display name here. Thanks!

What I'm gonna say is linux specific possibly, but the concepts are pretty much the same regardless

You've created a public private key pair using ssh-keygen so that you have a id_rsa, and id_rsa.pub (Use your preferred too here, on windows I always use cygwin ssh-user-config script and then import into other tools as required)

sftp id_rsa.pub onto your target machine.

ssh onto your target machine (which is of course Unix style)

  • mkdir ~/.ssh
  • cd ~/.ssh
  • cat ~/id_rsa.pub >> authorized_keys2
  • cd ..
  • chmod -R 700 .ssh


  • The last step is possibly optional depending on your umask, but I do tend to find that ssh servers get a bit uppity if the .ssh directory and contents are group/world readable.

    Logout and Login.

    authorized_keys2 is for ssh2 authentication, authorized_keys for ssh1 authentication. ssh2 is more secure than ssh1, and most servers should support it.

    I have no java certifications. This makes me a bad programmer. Ignore my post.
