go-rapidsnark witness calculator
Calculates witness, that can be passed to a prover (snarkjs, go-rapidsnark/prover or rapidsnark) to generate a zero-knowledge proof.
Installation
go get github.com/iden3/go-rapidsnark/witness
Dependencies
This package depends on wasmer shared library, which needs to be copied from wasmer-go module source code.
E.g. to run compiled project on Alpine linux you would need to copy /go/pkg/mod/github.com/wasmerio/wasmer-go@v1.0.4/wasmer/packaged/lib/linux-amd64/libwasmer.so from the build host/container.

Functions ¶
func ParseInputs ¶
ParseInputs parses WitnessCalc inputs from JSON that consist of a map of types which contain a recursive combination of: numbers, base-10 encoded numbers in string format, arrays.
Types ¶
type Circom2WitnessCalculator ¶
type Circom2WitnessCalculator struct {
// contains filtered or unexported fields
}
Circom2WitnessCalculator is the object that allows performing witness calculation from signal inputs using the WitnessCalc WASM module.
func NewCircom2WitnessCalculator ¶
func NewCircom2WitnessCalculator(wasmBytes []byte, sanityCheck bool) (*Circom2WitnessCalculator, error)
NewCircom2WitnessCalculator creates a new WitnessCalculator from the WitnessCalc loaded WASM module in the runtime.
func (*Circom2WitnessCalculator) CalculateBinWitness ¶
func (wc *Circom2WitnessCalculator) CalculateBinWitness(inputs map[string]interface{}, sanityCheck bool) ([]byte, error)
CalculateBinWitness calculates the witness in binary given the inputs.
func (*Circom2WitnessCalculator) CalculateWTNSBin ¶
func (wc *Circom2WitnessCalculator) CalculateWTNSBin(inputs map[string]interface{}, sanityCheck bool) ([]byte, error)
CalculateWTNSBin calculates the witness in binary given the inputs.
func (*Circom2WitnessCalculator) CalculateWitness ¶
func (wc *Circom2WitnessCalculator) CalculateWitness(inputs map[string]interface{}, sanityCheck bool) ([]*big.Int, error)
CalculateWitness calculates the witness given the inputs.
