Functions

func ArrayBigIntToString

func ArrayBigIntToString(bi []*big.Int) []string

ArrayBigIntToString converts an []*big.Int into []string, used to output the Public Signals

func ParsePk

func ParsePk(pkJSON []byte) (*types.Pk, error)

ParsePk parses the json []byte data into the Pk struct

func ParsePkBin

func ParsePkBin(f *os.File) (*types.Pk, error)

ParsePkBin parses binary file representation of the ProvingKey into the ProvingKey struct

func ParsePkGoBin

func ParsePkGoBin(f *os.File) (*types.Pk, error)

ParsePkGoBin parses go-snark binary file representation of the ProvingKey into ProvingKey struct (*types.Pk). PkGoBin is a own go-snark binary format that allows to go faster when parsing.

func ParseProof

func ParseProof(pj []byte) (*types.Proof, error)

ParseProof takes a json []byte and outputs the *Proof struct

func ParsePublicSignals

func ParsePublicSignals(pj []byte) ([]*big.Int, error)

ParsePublicSignals takes a json []byte and outputs the []*big.Int struct

func ParseVk

func ParseVk(vj []byte) (*types.Vk, error)

ParseVk takes a json []byte and outputs the *Vk struct

func ParseWitness

func ParseWitness(wJSON []byte) (types.Witness, error)

ParseWitness parses the json []byte data into the Witness struct

func ParseWitnessBin

func ParseWitnessBin(f *os.File) (types.Witness, error)

ParseWitnessBin parses binary file representation of the Witness into the Witness struct

func PkToGoBin

func PkToGoBin(pk *types.Pk) ([]byte, error)

PkToGoBin converts the ProvingKey (*types.Pk) into binary format defined by go-snark. PkGoBin is a own go-snark binary format that allows to go faster when parsing. nolint:gomnd

func ProofToJSON

func ProofToJSON(p *types.Proof) ([]byte, error)

ProofToJSON outputs the Proof i JSON format

func ProofToJSONHex

func ProofToJSONHex(p *types.Proof) ([]byte, error)

ProofToJSONHex outputs the Proof i JSON format with hexadecimal strings

Types
