Key tag accessors

Every PublicKey / PrivateKey carries a string "key tag" identifying which key pair it belongs to. The tag is set at key-generation time by OpenFHE and can be inspected or overwritten via these accessors. In threshold / multiparty protocols the tag is used to associate a key with the party that owns it; in single-user protocols it is typically left at its default.

Usage

get_key_tag(key, ...)

set_key_tag(key, ...)

Arguments

A PublicKey or PrivateKey.

Reserved for future method-specific arguments. set_key_tag accepts a value argument here.
