That's what keychain is for. Any special reason to reinvent the wheel, 
instead of using standard cygwin packages?

sdesc: "An OpenSSH key manager"
ldesc: "Keychain is an OpenSSH key manager, typically run from
~/.bash_profile. When run, it will make sure ssh-agent is running; if
not, it will start ssh-agent. It will redirect ssh-agent's output to
~/.ssh-agent, so that cron jobs that need to use ssh-agent keys can
simply source this file and make the necessary passwordless ssh
connections. In addition, when keychain runs, it will check with
ssh-agent and make sure that the ssh RSA/DSA keys that you specified on
the keychain command line have actually been added to ssh-agent. If not,
you are prompted for the appropriate passphrases so that they can be
added by keychain."

If these descriptions weren't clear to you, any improvement to them are 
welcome.
