kcapi_md_init — initialize cipher handle
int kcapi_md_init ( | struct kcapi_handle ** handle, |
| const char * ciphername, | |
uint32_t flags); |
handle[out] cipher handle filled during the call
ciphername[in] kernel crypto API cipher name as specified in /proc/crypto
flags[in] flags specifying the type of cipher handle
This function provides the initialization of a (keyed) message digest handle and establishes the connection to the kernel.
On success, a pointer to kcapi_handle object is returned in *handle. Function kcapi_md_destroy should be called afterwards to free resources.
return 0 upon success;
-ENOENT - algorithm not available;
-EOPNOTSUPP - AF_ALG family not available;
-EINVAL - accept syscall failed;
-ENOMEM - cipher handle cannot be allocated
