Generate a joint rotation-at-index key share — multi_eval_at_index_key

The EvalAtIndex flavor of multi_eval_automorphism_key_gen(); takes signed rotation indices rather than automorphism indices. Semantically equivalent but lives on a distinct C++ entry point, matching the openfhe-python surface.

Usage

multi_eval_at_index_key_gen(cc, sk, eval_key_map, index_list, key_tag = "")

Arguments

cc: A CryptoContext.
sk: This party's PrivateKey share.
eval_key_map: An existing EvalKeyMap.
index_list: Integer vector of signed rotation indices.
key_tag: Character; default "".

Value

An EvalKeyMap.
