       This function provides the initialization of a symmetric cipher handle and establishes the connection to
       the kernel.

       On success, a pointer to kcapi_handle object is returned in *handle. Function kcapi_cipher_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
