crypto_alloc_rng — - allocate RNG handle
struct crypto_rng * crypto_alloc_rng ( | const char * alg_name, |
| u32 type, | |
u32 mask); |
alg_nameis the cra_name / name or cra_driver_name / driver name of the message digest cipher
typespecifies the type of the cipher
maskspecifies the mask for the cipher
Allocate a cipher handle for a random number generator. The returned struct crypto_rng is the cipher handle that is required for any subsequent API invocation for that random number generator.
For all random number generators, this call creates a new private copy of
the random number generator that does not share a state with other
instances. The only exception is the “krng” random number generator which
is a kernel crypto API use case for the get_random_bytes function of the
/dev/random driver.
