Why gpg complains?

[Gary Greenberg]

I imported into GPG public keys that were generated by another
application.

Keys were accepted with no problem but when I am trying to encrypt with
these keys GPG gives me the following:

 

C:\Program Files\GNU\GnuPG>gpg -a -r utest3 -o
C:\sites\local\dig\test33.csv.gpg

 -e C:\sites\local\dig\loadSample.csv

gpg: 4985F643: There is no assurance this key belongs to the named user

 

pub  1024R/4985F643 2008-01-16 utest3 <foo at responsys.com>

 Primary key fingerprint: 1113 FC70 96BC DA77 E113  9805 F426 E5B2 4985
F643

 

It is NOT certain that the key belongs to the person named

in the user ID.  If you *really* know what you are doing,

you may answer the next question with yes.

 

Use this key anyway? (y/N) y

 

I did type 'Y" and file was successfully encrypted and later similarly
successfully decrypted.

Can someone tells me why it complains and how can I make GPG happy?

Thank you,

            Gary
