What should be the format of files used to generate public/private key pair in MakeKeys tool

Hi,

I need to create a reader enabled plugin. Adobe have approved my plugin and now I need to create a public and private key pairs. I read the documentation and trying to create the public and private key pair using the Makekeys tool in Acrobat 9 SDK. I am using the following command on command prompt to generate the keys.

MakeKeys -kp "D:\\keypair" -pk "D:\\publickey" abcd

where

KeyPairFileName = keypair.txt

PubKeyFileName = publickey.txt

RandomString = abcd

Please can anyone tell me what should be the format of KeyPairFileName and PubKeyFileName files?? Also, is it necessary that RandomString must be alphanumeric??

Thanks
