Actually you were correct the first time.  When you create a "DSA" key
in OpenPGP it actually creates a pair of keys.  DSA is a signature-only
key.  You cannot use "DSA" for encryption.  So OpenPGP also defines a
"DH" key (which technically isn't Diffie Hellman, technically it's an
El-Gamal key, but it's more related to DH than RSA) which you use for
encryption.  So yes, technically, you are creating a DH key.
