If you have a single (secret) subkey you can call:
gnutls_openpgp_privkey_get_subkey_pk_algorithm with index 0 to
retrieve the algorithm. You can also convert from key id to index
using:
gnutls_openpgp_privkey_get_subkey_idx().
The idea is that you use gnutls_openpgp_privkey_get_pk to retrieve the
main secret key algorithm only.
OK, this makes sense for just getting the algorithm of a subkey. But
what i'm looking to do is to get the secret subkey details directly.
For instance, if i'm looking at an RSA subkey, and i want to get at
the raw components of the subkey (prime, modulus, etc), how would i do
that from GnuTLS?
There is gnutls_openpgp_privkey_export_subkey_rsa_raw() and
gnutls_openpgp_privkey_export_subkey_dsa_raw(). Are they suitable for
what you want to do?
PS i'm happy having discussions like this on-list, if you'd prefer
them to be archived for other folks to find. i'm replying to this
privately because it was sent to me privately, but i won't mind if
you choose to publish it anywhere.
It was accidentally not forwarded to the list.
regards,
Nikos
