More ECC curves
In the development branch of GnuPG, there are more curves supported (Brainpool P-256, P-384, and P-512, and secp256k1).
Could you consider supporting more curves (than defined in RFC6637)?
The function oid_to_psize in parsePGP.ml causes an error, currently.
For supported curves in GnuPG, please see: http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=blob;f=common/openpgp-oid.c;h=28567b7fec69e58ac8a20df1ebe4707ad225e4ef;hb=refs/heads/master#l266
