how to generate public key from windows command prompt

Question

I need to generate public key to set up in ssh. How do I do it from windows command prompt? I tried using ssh-keygen -t rsa from c:\ but received a message ssh-keygen is not recognized as an internal or external command, operable program or batch file.

Answer 1

ssh-keygen isn't a windows executable.
You can use PuttyGen (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) for example to create a key

Answer 2

Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it.

After it is installed you can just go ahead and generate your public key if you want to put in on a server. You generate it by running:

ssh-keygen -t rsa 

After that you can just can just press enter, it will automatically assign a name for the key (example: id_rsa.pub)
