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.
