ecgroup

class ecgroup.ECGroup(builtin_cv)

Bases: object

EndBenchmark()

ends an ongoing benchmark

GetBenchmark(option)

retrieves benchmark results for any of these options: RealTime, CpuTime, Mul, Div, Add, Sub, Exp, Granular

GetGeneralBenchmarks()

retrieves benchmark count for all group operations

GetGranularBenchmarks()

retrieves group operation count per type: ZR and G

InitBenchmark()

initiates the benchmark state

StartBenchmark(options)

starts the benchmark with any of these options: RealTime, CpuTime, Mul, Div, Add, Sub, Exp, Granular

bitsize()

returns the bitsize for encoding messages in the group

coordinates(point)

get the X and Y coordinates of an EC point

debug(data, prefix=None)

decode(msg_bytes, include_ctr=False)

decode a group element into a string

deserialize(bytes_object)

deserializes into a pairing object

encode(message, include_ctr=False)

encode arbitrary string as a group element. Max size is dependent on the EC group order

groupSetting()

groupType()

hash(args, target_type=0)

hashes objects into ZR or G

Different object types may hash to the same element, e.g., the ASCII string ‘str’ and the byte string b’str’ map to the same element.

init(_type=0, value=None)

initializes an object with a specified type and value

order()

returns the order of the group

paramgen(secparam)

random(_type=0)

selects a random element in ZR or G

serialize(object)

serializes a pairing object into bytes

zr(point)

get the X coordinate only
