Perfectly valid. That's why it's called the "public" key.

Sounds like a minor misunderstanding on his part. You sign a message
with your private key, he verifies the signature with your public key.
You encrypt messages TO public keys (your and his) and then you each use
your private keys to decrypt them.
If I were in your shoes I'd simply encrypt the file to my key and his,
and send it to him. Chances are excellent that it will all work
according to plan.
