NAME

6       kcapi_akcipher_setpubkey - set the public key for the cipher handle
7

SYNOPSIS

9       int kcapi_akcipher_setpubkey(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 in DER format
18
19       keylen
20           [in] length of key buffer
21

DESCRIPTION

23       With this function, the caller sets the key for subsequent cipher
24       operations.
25
26       The key must be in DER format as follows
27
28       SEQUENCE { n INTEGER ({ rsa_get_n }), e INTEGER ({ rsa_get_e }) }
29
30       After the caller provided the key, the caller may securely destroy the
31       key as it is now maintained by the kernel.
32
33       return upon success the value of the maximum size for the asymmetric
34       operation is returned (e.g. the modulus size); a negative errno-style
35       error code if an error occurred
