Message hash is different from tonscan's message hash.

src_tx_hash:'8do0P2NEK7qtycZHniERQWGQ9Wy7BJQKtarpMkOa/gw='
hash:'5cOyEmX7zMOffQ41NkjeEuAfVaAFbGis8wIExCxlOVI='
src:'EQCN8t4vcAdfIinTuARZ49Ue3Wbx4XPUUET2KgVu579AhnYv'
dest:'EQDkLxDcJbXAlP3pzhrK6BRVLgYB538FENOIUQSBTWR6GypP'
the way we parse message.hash as below

message tlb.Message
msgCell, err := tlb.ToCell(message)
msg.Hash = msgCell.Hash()
hash = base64.StdEncoding.EncodeToString(msg.Hash)

But tonscan's message hash is 'ZpxcGqC4otnm2wIXgrSTMGaEmAe7f5UKgkPHV+bpNMQ='

Try calc hash of message.Msg (ExternalMessage type)

[fishTsai20]

this is internal message

[xssnick]

then hash InternalMessage type, same Msg field, not full tlb.Message

[fishTsai20]

I use msg field. the base64 the same as full tlb.Message. and still different from tonscan.
the hash I get: '5cOyEmX7zMOffQ41NkjeEuAfVaAFbGis8wIExCxlOVI=', but tonscan 'ZpxcGqC4otnm2wIXgrSTMGaEmAe7f5UKgkPHV+bpNMQ='
