2013-01-11Fix idea.c for big endian CPUs.Werner Koch1-7/+7
* cipher/idea.c: Replace use of WORDS_BIGENDIAN by BIG_ENDIAN_HOST. -- GnuPG-bug-id: 1461
2012-11-08Support the not anymore patented IDEA cipher algorithm.Werner Koch1-0/+411
* cipher/idea.c: New. Take from Libgcrypt master and adjust for direct use in GnuPG. * cipher/idea-stub.c: Remove. * cipher/Makefile.am: Add idea.c and remove idea-stub.c rules. * configure.ac: Remove idea-stub code. * g10/gpg.c (check_permissions): Remove code path for ITEM==2. (main): Make --load-extension a dummy option. * g10/keygen.c (keygen_set_std_prefs): Include IDEA only in PGP2 compatibility mode. * g10/misc.c (idea_cipher_warn): Remove. Also remove all callers. * g10/seckey-cert.c (do_check): Remove emitting of STATUS_RSA_OR_IDEA. * g10/status.c (get_status_string): Remove STATUS_RSA_OR_IDEA. * g10/status.h (STATUS_RSA_OR_IDEA): Remove. -- To keep the number of actually used algorithms low, we support IDEA only in a basically read-only way (unless --pgp2 is used during key generation). It does not make sense to suggest the use of this old 64 bit blocksize algorithm. However, there is old data available where it might be helpful to have IDEA available.
