cracen_get_rnd_in_range()

int cracen_get_rnd_in_range	(	const uint8_t *	n,
		size_t	nsz,
		uint8_t *	out )

#include <subsys/nrf_security/src/drivers/cracen/common/include/cracen/common.h>

Generate a random number within the specified range.

Note

This function generates a random number strictly less than the given upper limit (n). The generated random number is evenly distributed over the range [0, n-1]. If the range is invalid (e.g., n is zero, less than three, or even), an error code is returned.

Parameters

[in]	n	Pointer to a buffer holding the upper limit of the random range. The upper limit must be a non-zero odd number.
[in]	nsz	Size of the upper limit buffer in bytes.
[out]	out	Buffer to store the generated random number. The size of out should be at least nsz.

Returns

sxsymcrypt status code.
