openpgp to sexp conversion ..

Hi Friends,

My name is Kahnan and I am looking to convert openpgp keys in to sexp
including key data ..

Or is there any way I can use key management with libgcrypt?

Please advice

Thanks,
Kahnan

Explain 'sexp', please? When I hear someone talk about sexps, I think
they're talking about LISP S-expressions. I don't know if that's what
you have in mind.

yes sir it is LISP S-expressions....it's a canonical formate. open pgp has
it's own formate of keys and message and I want to convert this to sexp
format which is supported by libgcrypt protocol ..

any way apart from this if you know any auther solution for key management +
cryptolib then please explore.

Thanks,
Kahnan

This is likely about the S-expression format as used with spki.
Libgcrypt uses them to represent public key data. See

[I have not seen Kahnan mail (maybe spam filter issue). ]

The GnuPG SVN trunk has a lot of code to do the conversion. For
example:

gnupg/g10/pkglue.c
gnupg/common/sexputil.c

Shalom-Salam,

Werner
