函数名称:aes_expandkey - Expands the AES key as described in FIPS-197*@ctx: The location where the computed key will be stored.*@in_key: The supplied key.*@key_len: The length of the supplied key.* Returns 0 on success
函数原型:int aes_expandkey(struct crypto_aes_ctx *ctx, const u8 *in_key, unsigned int key_len)
返回类型:int
参数:
| 类型 | 参数 | 名称 |
|---|---|---|
| struct crypto_aes_ctx * | ctx | |
| const u8 * | in_key | |
| unsigned int | key_len |
| 196 | key_length等于key_len |
| 205 | rko[0]等于r32 - rotate a 32-bit value right*@word: value to rotate*@shift: bits to roll按位异或rc按位异或rki[0] |
| 210 | 如果key_len恒等于AES_KEYSIZE_192则 |
| 215 | 否则如果key_len恒等于AES_KEYSIZE_256则 |
| 237 | key_dec[i]等于inv_mix_columns(key_enc[j]) |
| 238 | key_dec[i + 1]等于inv_mix_columns(key_enc[j + 1]) |
| 239 | key_dec[i + 2]等于inv_mix_columns(key_enc[j + 2]) |
| 240 | key_dec[i + 3]等于inv_mix_columns(key_enc[j + 3]) |
| 248 | 返回:0 |
