2.13.ipv8.attestation.wallet.pengbaorange.structs._serialize_fp2value(value: 2.13.ipv8.attestation.wallet.primitives.value.FP2Value) → bytes: Convert an FP2Value to bytes.

2.13.ipv8.attestation.wallet.pengbaorange.structs._unserialize_fp2value(mod: int, value: bytes) → tuple[2.13.ipv8.attestation.wallet.primitives.value.FP2Value, bytes]: Decode serialized bytes back into an FP2Value of the given modulus.

The proof structure that a commitment hides a value within a certain range.

serialize() → bytes: Convert this commitment to bytes.

classmethod unserialize(s: bytes) → tuple[PengBaoCommitment, bytes]: Convert bytes to a commitment.

class 2.13.ipv8.attestation.wallet.pengbaorange.structs.PengBaoCommitmentPrivate(m1: int, m2: int, m3: int, r1: int, r2: int, r3: int)

Private part of the PengBaoCommitment.

MSGSPACE: list[int]

generate_response(s: int, t: int) → tuple[int, int, int, int]

Given s and t and our private information, generate the appropriate response.

The calling function should make sure s and t are large integers (at least larger than 0).

Parameters:

s (int) – the challenge value s
t (int) – the challenge value t

Returns:

the challenge response

Return type:

int

serialize() → bytes: Convert this commitment to bytes.

classmethod unserialize(s: bytes) → tuple[PengBaoCommitmentPrivate, bytes]: Convert bytes to a commitment.

encode(PK: 2.13.ipv8.attestation.wallet.primitives.structs.BonehPublicKey) → bytes: Serialize and encode using a given public key.

classmethod decode(SK: 2.13.ipv8.attestation.wallet.primitives.structs.BonehPrivateKey, s: bytes) → PengBaoCommitmentPrivate: Decode an encoded PengBaoCommitmentPrivate using a secret key.

class 2.13.ipv8.attestation.wallet.pengbaorange.structs.PengBaoPublicData(PK: 2.13.ipv8.attestation.wallet.primitives.structs.BonehPublicKey, bitspace: int, commitment: PengBaoCommitment, el: 2.13.ipv8.attestation.wallet.pengbaorange.boudot.EL, sqr1: 2.13.ipv8.attestation.wallet.pengbaorange.boudot.SQR, sqr2: 2.13.ipv8.attestation.wallet.pengbaorange.boudot.SQR)

Public data required to verify a Peng Bao proof.

check(a: int, b: int, s: int, t: int, x: int, y: int, u: int, v: int) → bool: Check whether the given range is correct.

serialize() → bytes

Serialize this Attestation to a string.

Returns:: the serialized form of this attestation
Return type:: str

classmethod unserialize(s: bytes) → tuple[PengBaoPublicData, bytes]

Given a string, create an Attestation object.

Parameters:: s (str) – the string to unserialize
Returns:: the attestation object
Return type:: PengBaoPublicData
