Bitcoin Core. DER and the SIGHASH encoding allow for quite some flexibility in how the same structures
are encoded, and this can open up novel attacks in which a man in the middle takes a transaction and then
changes its signature such that the transaction hash is different but it's still valid. This can confuse wallets
and generally violates people's mental model of how Bitcoin should work, thus, non-canonical signatures are now
not relayed by default. | [
