func ArrayToChaincodeArgs(args []string) [][]byte
ArrayToChaincodeArgs converts array of string args to array of []byte args
func ComputeSHA256(data []byte) (hash []byte)
ComputeSHA256 returns SHA2-256 on data
func ComputeSHA3256(data []byte) (hash []byte)
ComputeSHA3256 returns SHA3-256 on data
func ConcatenateBytes(data ...[]byte) []byte

func CreateUtcTimestamp() *timestamp.Timestamp
CreateUtcTimestamp returns a google/protobuf/Timestamp in UTC
func ExtractRemoteAddress(ctx context.Context) string
func FindMissingElements(all []string, some []string) (delta []string)
FindMissingElements identifies the elements of the first slice that are not present in the second The second slice is expected to be a subset of the first slice
func Flatten(i interface{}) []string
`flatten` recursively retrieves every leaf node in a struct in depth-first fashion and aggregate the results into given string slice with format: "path.to.leaf = value" in the order of definition. Root name is ignored in the path. This helper function is useful to pretty-print a struct, such as configs. for example, given data structure: A{
B{
C: "foo",
D: 42,
},
E: nil,
} it should yield a slice of string containing following items: [
"B.C = \"foo\"", "B.D = 42", "E =",
]
func GenerateBytesUUID() []byte
GenerateBytesUUID returns a UUID based on RFC 4122 returning the generated bytes
func GenerateHashFromSignature(path string, args []byte) []byte
GenerateHashFromSignature returns a hash of the combined parameters
func GenerateIDWithAlg(customIDgenAlg string, payload []byte) (string, error)
GenerateIDWithAlg generates an ID using a custom algorithm
func GenerateIDfromTxSHAHash(payload []byte) string
GenerateIDfromTxSHAHash generates SHA256 hash using Tx payload
func GenerateIntUUID() *big.Int
GenerateIntUUID returns a UUID based on RFC 4122 returning a big.Int
func GenerateUUID() string
GenerateUUID returns a UUID based on RFC 4122
func GetSysCCVersion() string
GetSysCCVersion returns the version of all system chaincodes This needs to be revisited on policies around system chaincode "upgrades" from user and relationship with "fabric" upgrade. For now keep it simple and use the fabric's version stamp
func GetTestChainID() string
