NAME¶

kcapi_akcipher_setkey - set the private key for the cipher handle

SYNOPSIS¶

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

ARGUMENTS¶

handle

key

keylen

DESCRIPTION¶

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

The key must be in DER format as follows

SEQUENCE { version INTEGER, n INTEGER ({ rsa_get_n }), e INTEGER ({ rsa_get_e }), d INTEGER ({ rsa_get_d }), prime1 INTEGER, prime2 INTEGER, exponent1 INTEGER, exponent2 INTEGER, coefficient INTEGER }

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

return 0 upon success; a negative errno-style error code if an error occurred
