Arguments

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

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
