On the send side you would do the check when MSG_MORE is unset. On the receive side you should stop waiting only when ctx->more is false and the send-side check succeeded. Perhaps rename ctx->more to ctx->done and then you can use it to indicate to the receive side that we're ready and have valid data for it. The receive side can then simply wait for ctx->done to become true. > > PS we should add a length check for missing/partial auth tags > > to crypto_aead_decrypt.

We should at least add a check in crypto_aead_decrypt first so as to guarantee nothing slips through.
