as this adds a new path in chain-abci, perhaps bump a version to "0.4.1" + update a changelog (instead of *Unreleased* ## v0.5.0 it could be *Unreleased* ## v0.4.1)?
-- or bump to / keep it in v0.5.0 if this goes ahead #1466

decrypt?
Thanks, done.

instead of this custom xor, it could just import and use AEAD + aes-gcm-siv ?

There's now this pure Rust sealing: https://github.com/crypto-com/chain/blob/master/chain-tx-enclave/enclave-utils/src/lib.rs
instead of this custom, it could just produce mock payloads that correspond to the Intel SDK payloads, but it won't be deriving key using the "egetkey" instruction -- it'll just have one hardcoded mock key

I feel that simple xor may be good enough for the mock purpose?
After all, it's only for dev/testing purpose, people should bear in mind that there's always potential false positive and false negatives?

these were just small suggestions -- the main requested change is just updating the changelog; it's ok to merge this without this improved mocking for now
… platform Solution: - Add mock mode - Fix warning of release building, Fix crypto-com#1465
