CRYPTO_ALLOC_RNG(9) Programming Interface CRYPTO_ALLOC_RNG(9)
NAME
crypto_alloc_rng - - allocate RNG handle
SYNOPSIS
struct crypto_rng * crypto_alloc_rng(const char * alg_name, u32 type, u32 mask);
ARGUMENTS
alg_name
is the cra_name / name or cra_driver_name / driver name of the message digest cipher
type
specifies the type of the cipher
mask
specifies the mask for the cipher
DESCRIPTION
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.
RETURN
allocated cipher handle in case of success; IS_ERR is true in case of an error, PTR_ERR
returns the error code.
