+2014-01-26 Niels Möller <nisse@lysator.liu.se>
+
+ * nettle-internal.h (_NETTLE_AEAD_FIX): Renamed to...
+ (_NETTLE_AEAD): ... new name, and deleted old definition. Also use
+ _set_nonce instead of _set_iv.
+ * nettle-internal.c (nettle_gcm_aes128, nettle_gcm_aes192)
+ (nettle_gcm_aes256): Define in terms of new interface.
+ (nettle_eax_aes128): Updated for _NETTLE_AEAD changes.
+
+ * testsuite/gcm-test.c (test_gcm_hash): Likewise use struct
+ gcm_aes128_ctx.
+ (test_main): Added a testcase using the old interface based on
+ struct gcm_aes_ctx.
+
+ * examples/nettle-benchmark.c (time_gcm): Update to use new struct
+ gcm_aes128_ctx. Also use name "gcm-aes128" in output.
+
+ * gcm.h: New interface for gcm_aes128, gcm_aes192, gcm_aes256,
+ using the new AES interface.
+ (GCM_CTX): Reorder fields, putting the cipher context
+ last.
+
+ * Makefile.in (nettle_SOURCES): Added gcm-aes128.c, gcm-aes192.c,
+ and gcm-aes256.c.
+
+ * gcm-aes128.c: New file.
+ * gcm-aes192.c: New file
+ * gcm-aes256.c: New file.
+
2014-01-25 Niels Möller <nisse@lysator.liu.se>
* gcm.h (GCM_SET_KEY): Deleted length argument.
