Issue in Importing a PGP signature key

[amit bhalerao]

Hi ,

	Our upstream system is using a PGP to encrypt the file . We have a  
GPG installed on our system . However when i try to import the PGP  
signature key into our system , I am getting following error message.
*****
tosk[etrut]:/ngs/app/etrut $ gpg --import HTST126A.pass.asc
gpg: WARNING: using insecure memory!
gpg: please see http://www.gnupg.org/faq.html for more information
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

*****
Any idea why?
