Add PayToPubKeyHashScript and SignatureScript functions. PayToPubKeyHashScript generates a new pay to pubkey hash script to use as the pkScript when creating new transactions. If the passed pubkey hash is an invalid size, StackErrInvalidOpcode will be returned as an error. SignatureScript returns the signature script necessary to validate a single input of a transaction. This also adds sanity checking for serializing scripts into byte slices. If the length of a serialized opcode does not equal the expected length, StackErrInvalidOpcode will be returned when unparsing a []parsedOpcode. New internal tests were added to verify checks for valid and invalid parsed opcodes.

pkScript []byte // output script of previous tx
idx int // tx idx to be run.
bip16 bool // is bip16 active?
Add flag bitmask to NewScript for canonical sig checks. This removes the bip16 bool from NewScript and adds it to flags (with the constant ScriptBip16), and also adds a new flag, ScriptCanonicalSignatures, which will call btcec.ParseDERSignature parsing a signature during an Execute. This is needed to emulate bitcoind behavior, as bitcoind performs canonical signature validation (DER format) in some places (like mempool acceptance) but not others (like block validation). Updated tests and test coverage file to reflect changes.

Add flag bitmask to NewScript for canonical sig checks. This removes the bip16 bool from NewScript and adds it to flags (with the constant ScriptBip16), and also adds a new flag, ScriptCanonicalSignatures, which will call btcec.ParseDERSignature parsing a signature during an Execute. This is needed to emulate bitcoind behavior, as bitcoind performs canonical signature validation (DER format) in some places (like mempool acceptance) but not others (like block validation). Updated tests and test coverage file to reflect changes.

Add PayToPubKeyHashScript and SignatureScript functions. PayToPubKeyHashScript generates a new pay to pubkey hash script to use as the pkScript when creating new transactions. If the passed pubkey hash is an invalid size, StackErrInvalidOpcode will be returned as an error. SignatureScript returns the signature script necessary to validate a single input of a transaction. This also adds sanity checking for serializing scripts into byte slices. If the length of a serialized opcode does not equal the expected length, StackErrInvalidOpcode will be returned when unparsing a []parsedOpcode. New internal tests were added to verify checks for valid and invalid parsed opcodes.

If the passed pubkey hash is an invalid size, StackErrInvalidOpcode will be returned as an error. SignatureScript returns the signature script necessary to validate a single input of a transaction. This also adds sanity checking for serializing scripts into byte slices.

Add PayToPubKeyHashScript and SignatureScript functions. PayToPubKeyHashScript generates a new pay to pubkey hash script to use as the pkScript when creating new transactions. If the passed pubkey hash is an invalid size, StackErrInvalidOpcode will be returned as an error. SignatureScript returns the signature script necessary to validate a single input of a transaction. This also adds sanity checking for serializing scripts into byte slices. If the length of a serialized opcode does not equal the expected length, StackErrInvalidOpcode will be returned when unparsing a []parsedOpcode. New internal tests were added to verify checks for valid and invalid parsed opcodes.

Add flag bitmask to NewScript for canonical sig checks. This removes the bip16 bool from NewScript and adds it to flags (with the constant ScriptBip16), and also adds a new flag, ScriptCanonicalSignatures, which will call btcec.ParseDERSignature parsing a signature during an Execute. This is needed to emulate bitcoind behavior, as bitcoind performs canonical signature validation (DER format) in some places (like mempool acceptance) but not others (like block validation). Updated tests and test coverage file to reflect changes.
