fips: Explicitly allow only some PK flags.
* src/fips.c (_gcry_fips_indicator_pk_flags): New function for explicit FIPS indicator for public key algorithm flags. * src/g10lib.h (_gcry_fips_indicator_pk_flags): New. * src/gcrypt.h.in (GCRYCTL_FIPS_SERVICE_INDICATOR_PK_FLAGS): New. * src/global.c (_gcry_vcontrol): Handle the new option. * doc/gcrypt.texi: Document new options. -- Signed-off-by: Jakub Jelen <jjelen@redhat.com>
