  8. def checkSignature(txSignatureComponent: TxSigComponent, script: Seq[ScriptToken], pubKey: ECPublicKeyBytes, signature: ECDigitalSignature, flags: Seq[ScriptFlag] = Policy.standardFlags): TransactionSignatureCheckerResult

    Checks the signature of a scriptSig in the spending transaction against the given scriptPubKey & explicitly given public key This is useful for instances of non standard scriptSigs

    Checks the signature of a scriptSig in the spending transaction against the given scriptPubKey & explicitly given public key This is useful for instances of non standard scriptSigs

    txSignatureComponent

    the relevant transaction information for signature checking

    script

    the current script state inside the interpreter - this is needed in the case of OP_CODESEPARATORS

    pubKey

    the public key the signature is being checked against

    signature

    the signature which is being checked against the transaction & the public key

    flags

    the script flags used to check validity of the signature

    returns

    a boolean indicating if the signature is valid or not

    This is a helper function to check digital signatures against public keys if the signature does not match this public key, check it against the next public key in the sequence

    This is a helper function to check digital signatures against public keys if the signature does not match this public key, check it against the next public key in the sequence

    txSignatureComponent

    the tx signature component that contains all relevant transaction information

    script

    the script state this is needed in case there is an OP_CODESEPARATOR inside the script

    sigs

    the signatures that are being checked for validity

    pubKeys

    the public keys which are needed to verify that the signatures are correct

    flags

    the script verify flags which are rules to verify the signatures

    returns

    a boolean indicating if all of the signatures are valid against the given public keys
