kcapi_akcipher_setpubkey - Man Page

int kcapi_akcipher_setpubkey(struct kcapi_handle * handle, const uint8_t * key, uint32_t keylen);

handle

key

keylen

With this function, the caller sets the key for subsequent cipher operations​.

The key must be in DER format as follows

SEQUENCE { n INTEGER ({ rsa_get_n }), e INTEGER ({ rsa_get_e }) }

After the caller provided the key, the caller may securely destroy the key as it is now maintained by the kernel​.

return upon success the value of the maximum size for the asymmetric operation is returned (e​.g​. the modulus size); a negative errno-style error code if an error occurred
