Failed to use key file

Question

I created the username using the following command ssh -keygen -b 1024 -f user -t dsa and now I am trying to use putty to enter my private key, but this does not work. Do you receive the following error message?

Unable to use key file C:\Users\admin\Desktop\da.ppk (OpenSSH SSH-2 private key)

I just created a notebook called da.ppk

You will need to convert this key with PuTTYgen ( http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html ) into a key that can be used with PuTTY.

Steps:

• Download PuTTYgen.
• Upload your key
• Save Private Key
