Hi,
I wanted to use SFTP as file transfer protocol using putty. I have created Public as private keys as per the above instruction.
But want to know how to use it?
Is one server will have only one private and public key or more than on keys?

Hi,
My requirement is to receive files from a unix machhine(SFTP server) to a windows machine.I have already generated the public key and private key using puttygen.

I have generated the keys using a remote logon on the windows.Do the ID's be same on the Unix and windows box or can I use the login credentials of the unix box in the psftpcommand line prompt.

Regards,
Vamsi

A note for anyone who has seen 'server refused our key' error: When you try using the key generated with puttygen, make sure to use the OPENSSH format key on the server side. openssh doesn't understand the puttygen format of key.
Alternatively you can generate your key with ssh-keygen. More info here: http://www.walkernews.net/2009/03/22/how-to-fix-server-refused-our-key-error-that-caused-by-putty-generated-rsa-public-key/

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Public keys are placed in the file authorized_keys in the .ssh sub directory of
the account's home directory. It's definitely a particular format, a single
line:

ssh-rsa TypicallyLongPublicKeyValue

and probably needs a particular permission setting. I typically set the file
and the .ssh directory to be rw and rwx respectively for the owning account
only).

Hi,
Do we have any open source to manage keys? Any open source to give certificate of authenticity?

Regards,
Vineet

Using Putty Key Generator, if I choose "Save Private Key", the only "save as" file type is ppk.

There are also two Conversion options, "Export OpenSSH Key" and "Export ssh.com Key" Neither of these options provide a specific file type such as PEM.

How does one generate a PEM formatted private key?

PuttyGen allows to export in different formats. I've done exactly that.

Great article! I'm using FTPShell which requires the private key to be in the PEM format. Can I convert PuttyGen's PPK output to PEM? If not, there another program that can generate a PEM formatted private key?

It sounds like a configuration issue on your server side. I regularly do exactly what you describe without problems, on several servers.

It seems as though sftp and ssh CAN NOT BE USED together.

When I invokes sftp (first) the server asks me to authenticate the public key then continues conneting.

Afterwards when I invoke ssh I receive a msg indicating the key is already present and it WILL NOT connect.

Any suggestions
