crypto_des_verify

函数名称：rypto_des_verify_key - Check whether a DES key is weak*@tfm: the crypto algo*@key: the key buffer* Returns -EINVAL if the key is weak and the crypto TFM does not permit weak* keys

函数原型：static inline int crypto_des_verify_key(struct crypto_tfm *tfm, const u8 *key)

返回类型：int

参数：

类型	参数	名称
struct crypto_tfm *	tfm
const u8 *	key

err等于des_expand_key - Expand a DES input key into a key schedule*@ctx: the key schedule*@key: buffer containing the input key*@len: size of the buffer contents* Returns 0 on success, -EINVAL if the input key is rejected and -ENOKEY if

如果err恒等于负ENOKEY则

如果crypto_tfm_get_flags(tfm)按位与CRYPTO_TFM_REQ_FORBID_WEAK_KEYS则err等于负EINVAL

否则err等于0

如果err则crypto_tfm_set_flags(tfm, CRYPTO_TFM_RES_WEAK_KEY)

memzero_explicit - Fill a region of memory (e
