Your export didn't export your secret key. Exporting secret keys has
certain security risks. See --export-secret-key in the 1.4.0 man page.
BTW, you want to make positive you have 1.4.0a on the Windows box.
On your windows box, open a CMD window and run
I bet only the public key is there.
I don't know your network setup, but you could more easily transfer the
public and secret keyring files (in binary) over a secure network
connection (scp or sftp) or on a FAT formatted floppy.
If the transfer is always going to be from the AIX box to the NT box, you
don't need nor do you *REALLY* want your secret key on the AIX box.
Generate a keypair sans passphrase on the NT box and export the PUBLIC key
to the AIX box. Use that to encrypt TO the NT box. Each secret key should
have only one home - especially one with no passphrase.
If you are encrypting data both ways consider a pair of keypairs (easily
extended to more machines), with each machine having it's own
public+secret keypair along with the public key(s) of the machine(s) it's
sending encypted files.
You can even sign and encrypt using the two keypair scheme: AIX uses its
secret key to sign the file, then encrypts it to NT's public key. The
encrypted data is transferred. NT then uses its secret key to decrypt the
file and AIX's public key to verify the signature.
This is a good approach if you're emailing the files. But if you're
transferring directly from one machine to the other with no relays, you
may want to look at OpenSSH and scp or sftp as a better mousetrap to more
easily solve this problem.
