NAME

6       kcapi_cipher_setkey - set the key for the cipher handle
7

SYNOPSIS

9       int kcapi_cipher_setkey(struct kcapi_handle * handle,
10                               const uint8_t * key, uint32_t keylen);
11

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 encryption
24       or decryption operations.
25
26       After the caller provided the key, the caller may securely destroy the
27       key as it is now maintained by the kernel.
28
29       return 0 upon success (in case of an akcipher handle, a positive
30       integer is returned that denominates the maximum output size of the
31       cryptographic operation -- this value must be used as the size of the
32       output buffer for one cryptographic operation); a negative errno-style
33       error code if an error occurred
