| | | | | | | | | (gcm_set_iv): Added support for IVs of arbitrary size. Needed another argument, for the hash subkey. (gcm_digest): Use gcm_hash_sizes. Rev: nettle/gcm.c:1.13 Rev: nettle/gcm.h:1.8

| | | | | | | | | | | | | | | | | | | | | | | | | gcm_key *. (gcm_hash): Replaced context argument by a struct gcm_key * and a pointer to the hashing state block. (gcm_auth): Added struct gcm_key * argument. (gcm_encrypt): Likewise. (gcm_decrypt): Likewise. (gcm_digest): Likewise. * gcm.h (struct gcm_key): Moved the key-dependent and message-independent state to its own struct. (struct gcm_ctx): ... and removed it here. (GCM_CTX): New macro.

| | | | | | | | | | | | | | | | | | | (gcm_gf_mul): Compile bitwise version only when GCM_TABLE_BITS == 0. Simplified interface with just two arguments pointing to complete blocks. (gcm_gf_shift_4, gcm_gf_shift_8): Renamed table-based functions, from... (gcm_gf_shift_chunk): ... old name. (gcm_gf_mul): Renamed both table-based versions and made the argument types compatible with the bitwise gcm_gf_mul. (gcm_gf_mul_chunk): ... the old name. (gcm_set_key): Initialize the table using adds and shifts only. When GCM_TABLE_BITS > 0, this eliminates the only use of the bitwise multiplication. (gcm_hash): Simplified, now that we have the same interface for gcm_gf_mul, regardless of table size. Rev: nettle/ChangeLog:1.140 Rev: nettle/gcm.c:1.11
* * gcm.c (GHASH_POLYNOMIAL): Use unsigned long for this constant.Niels Möller2011-02-081-5/+6
| | | | | | | | (gcm_gf_shift_chunk): Fixed bugs for the big endian 64-bit case, e.g., sparc64. For both 4-bit and 8-bit tables. Rev: nettle/ChangeLog:1.139 Rev: nettle/gcm.c:1.10

| | | | | | | | | (gcm_gf_add): New function, a special case of memxor. Use it for all memxor calls with word-aligned 16 byte blocks. Improves performance to 152 cycles/byte with no tables, 28 cycles per byte with 4-bit tables and 10.5 cycles per byte with 8-bit tables. Rev: nettle/gcm.c:1.7
