-The total length of ''SigMsg()'' is ''442'' 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.
