Functions

func CheckDataInField

func CheckDataInField(data []byte) bool

CheckDataInField checks if data is in Q field

func CreateSchemaHash

func CreateSchemaHash(schemaBytes []byte,
	credentialType string) core.SchemaHash

CreateSchemaHash computes schema hash from content and credential type

func DataFillsSlot

func DataFillsSlot(slot, newData []byte) bool

DataFillsSlot checks if newData fills into slot capacity ()

func FieldToByteArray

func FieldToByteArray(field interface{}) ([]byte, error)

FieldToByteArray convert fields to byte representation based on type

func FillClaimSlots

func FillClaimSlots(content []byte,
	indexFields, valueFields []string) (processor.ParsedSlots, error)

FillClaimSlots fullfils index and value fields to iden3 slots

func IndexOf

func IndexOf(field string, fields []string) int

IndexOf returns field index in array of fields

func Keccak256

func Keccak256(data ...[]byte) []byte

Keccak256 calculates the Keccak256 hash of the input data.

func SwapEndianness

func SwapEndianness(buf []byte) []byte

SwapEndianness swaps the endianness of the value encoded in buf. If buf is Big-Endian, the result will be Little-Endian and vice-versa.
