* g10/misc.c (openpgp_pk_algo_name): New. Replace all calls in g10/ to gcry_pk_algo_name by a call to this function. (map_pk_openpgp_to_gcry): Map algo PUBKEY_ALGO_ELGAMAL_E to GCRY_PK_ELG. (openpgp_pk_test_algo): Use PUBKEY_ALGO_ELGAMAL_E instead of GCRY_PK_ELG_E. Return an error for ECC algos. (openpgp_pk_test_algo2): Return an error for ECC algos. * g10/gpg.c (build_list): Avoid printing ECC two times. * include/cipher.h: Do not use GCRY_PK_* macros for PUBKEY_ALGO_*. -- Due to recent changes to adjust for use with Libgcrypt 1.6, "gpg --version" printed two question marks. This patches fixes that and also make sure that gpg does advertise any ECC features. The patch in build_list is not really needed. Signed-off-by: Werner Koch <wk@gnupg.org>
