 '''''NEW''''' If the input under consideration is a pegin input, the fields ''nAsset'', ''nValue'' and ''scriptPubKey'', where they appear, are taken from the pegin witness data. The asset used is the asset ID on the sidechain, not that on the parent chain (if any).

 The total length of ''SigMsg()'' is ''443'' bytes for <code>ANYONECANPAY</code> sighashes, ''366'' bytes for non-<code>ANYONECANPAY</code> sighashes, and both numbers are reduced by 64 bytes for <code>SIGHASH_NONE</code> sighashes. Note that this does not include the size of sub-hashes such as ''sha_prevouts'', which may be cached across signatures of the same transaction.
