| 2 | * aes.h | |
| 3 | * | |
| 4 | * Header file declaring AES functions. | |
| 5 | * | |
| 6 | * Copied from the upstream qemu git tree revision | |
| 7 | * 55616505876d6683130076b810a27c7889321560 | |
| 8 | * but was introduced there by Fabrice Bellard in | |
| 9 | * e4d4fe3c34cdd6e26f9b9975efec7d1e81ad00b6 | |
| 10 | * AES crypto support | |
| 11 | * git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@1036 \ | |
| 12 | * c046a42c-6fe2-441c-8c8c-71466251a162 | |
| 13 | * | |
| 14 | * Modified by Ian Jackson to change the guard #define from | |
| 15 | * QEMU_AES_H to AES_H and to add some needed system #include's. | |
| 16 | * | |
| 17 | * The header file doesn't appear to have a separate copyright notice | |
| 18 | * but is clearly a lightly edited (by Bellard) version of code from | |
| 19 | * Rijmen, Bosselaers and Barreto. | |
| 20 | * | |
| 21 | * The original is from rijndael-alg-fst.c, with this copyright | |
| 22 | * notice: | |

| 24 | * rijndael-alg-fst.c | |
| 25 | * | |
| 26 | * @version 3.0 (December 2000) | |
| 27 | * | |
| 28 | * Optimised ANSI C code for the Rijndael cipher (now AES) | |
