We're trying to parse existing keys on a wide variety of platforms so
that we can convert between various formats. This an essential part of
our idea to make the gpg key the master crypto identity, and then use
subkeys for various other applications, like OTR, TextSecure, S/MIME,
etc. Then the user will only need to deal with one single key for trust
Right now, we are starting out by generating DSA subkeys in gpg, and
exporting them for use in OTR. libotr's private key format is a
hex-based S-expression. The subkey export format for gpg v2.0 is not
clear to us, so any pointers on docs or the place in the gpg code to
figure that out would be most appreciated.
