expander: panic if requested output length overflows DST. - #664
Merged
Conversation
As required by RFC 9380, the DST encodes the requested length as a 2 byte integer. If the length exceeds 2^16 - 1, then panic. The API already documents this behavior, but doesn't actually implement it as documented.
