Import the key and then:

$ gpg --list-keys --with-key-data KEYID

In the output look for pkd records:

If field 1 has the tag "pkd", a listing looks like this:
pkd:0:1024:B665B1435F4C2 .... FF26ABB:
    !  !   !-- the value
    !  !------ for information: number of bits in the value
    !--------- index (eg. DSA goes from 0 to 3: p,q,g,y)

The entire format is decribed in doc/DETAILS.


Salam-Shalom,
