-cskpass and -csjpin must be specified if -register is specified
This message appears when you try to run the blackberry-signer tool with the register option, but you did not include both the cskpass and csjpin options.
The blackberry-signer tool tries to encrypt communication between your computer and the RIM Signing Authority. The tool stores the encryption keys in an encrypted file that is unlocked by using the password you provide in the cskpass option.
The CSJ Pin is a 6 - 10 digit number you selected when you requested permission to sign applications. The number is designed to verify that the CSJ registration file is used by the person who requested it.
Add the cskpass and csjpin options to your command line. Make sure that you provide appropriate values for each option.
