RedHat Rsa public private key matching

Hi All,

I have a requirement where i need to check if an rsa public key corresponds to a private key and hence return success or failure. Currently i am using the command

Code:
diff <( ssh-keygen -y -e -f "$PRIVKEY" ) <( ssh-keygen -y -e -f "$PUBLICKEY" )

and its solving my purpose. This is in a shell script. But i also want to incorporate the pass phrase in the validation process so that it becomes a dual layer matching, first the pass phrase and then the key matching. Is my approach right above? Can you please suggest any better option.

NAME
gnunet-rsa - manipulate GNUnet RSA key files SYNOPSIS
gnunet-rsa [options]FILENAME DESCRIPTION
gnunet-rsa can be used to create an RSA private key and to print the corresponding public key. You must specify a filename containing an RSA private key in GNUnet format as an argument. If the file does not exist, gnunet-rsa will create a key. This may then take a while. If the option -p is given, the corresponding public key will be printed to the console. OPTIONS
-p, --print-public-key Print the corresponding public key to stdout. -P, --print-peer-identity Print the corresponding peer identity (hash of the public key) to stdout. This hash is used for the name of peers. -s, --print-short-identity Print the corresponding short hash (256-bit hash of the public key) to stdout. This hash is used for names in the zkey zone. -c FILENAME, --config=FILENAME Use the configuration file FILENAME. -h, --help Print short help on options. -L LOGLEVEL, --loglevel=LOGLEVEL Use LOGLEVEL for logging. Valid values are DEBUG, INFO, WARNING and ERROR. -v, --version Print GNUnet version number. BUGS
Report bugs by using Mantis <https://gnunet.org/bugs/> or by sending electronic mail to <gnunet-developers@gnu.org> GNUnet Mar 15, 2012 GNUNET-RSA(1)
