SYNOPSIS

9       int kcapi_md_setkey(struct kcapi_handle * handle, const uint8_t * key,
10                           uint32_t keylen);

ARGUMENTS

13       handle
14           [in] cipher handle
15
16       key
17           [in] key buffer
18
19       keylen
20           [in] length of key buffer
21

DESCRIPTION

23       With this function, the caller sets the key for subsequent hashing
24       operations. This call is applicable for keyed message digests.
25
26       After the caller provided the key, the caller may securely destroy the
27       key as it is now maintained by the kernel.
