The ScriptVerifyMinimalData enforces that all push operations use the
minimal data push required. This is part of BIP0062.
This commit mimics Bitcoin Core commit
698c6abb25c1fbbc7fa4ba46b60e9f17d97332ef
Remove ScriptCanonicalSignatures and use the new
ScriptVerifyDERSignatures flag. The ScriptVerifyDERSignatures
flag accomplishes the same functionality.
This commit adds two new verification flags to txscript named
ScriptVerifyStrictEncoding and ScriptVerifyDerSignatures.
The ScriptVerifyStrictEncoding flag enforces signature scripts
and public keys to follow the strict encoding requirements.
The ScriptVerifyDerSignatures flag enforces signature scripts
to follow the strict encoding requirements.
These flags mimic Bitcoin Core's SCRIPT_VERIFY_STRICTENC and
SCRIPT_VERIFY_DERSIG flags and brings the Bitcoin Core test scripts up
to date.
This commit contains the entire btcscript repository along with several
changes needed to move all of the files into the txscript directory in
order to prepare it for merging. This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.
- All import paths in the old btcscript test files have been changed to the
new location
- All references to btcscript as the package name have been chagned to
txscript
This is ongoing work toward #214.
