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

type

mask

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.
