Method overview

void final(in ACString aB, in ACString aGVB, in ACString aRB, in ACString aHkdfInfo, out ACString aAES256Key, out ACString aHMAC256Key);

void round1(in ACString aSignerID, out ACString aGX1, out ACString aGV1, out ACString aR1, out ACString aGX2, out ACString aGV2, out ACString aR2);

void round2(in ACString aPeerID, in ACString aPIN, in ACString aGX3, in ACString aGV3, in ACString aR3, in ACString aGX4, in ACString aGV4, in ACString aR4, out ACString aA, out ACString aGVA, out ACString aRA);

Methods

final()

Perform the final step of the JPAKE exchange. This will compute the key and expand the key to two keys, an AES256 encryption key and a 256 bit HMAC key. It returns a key confirmation value (SHA256d of the key) and the encryption and HMAC keys.

void final(
  in ACString aB,
  in ACString aGVB,
  in ACString aRB,
  in ACString aHkdfInfo,
  out ACString aAES256Key,
  out ACString aHMAC256Key
);

Parameters

aB

Schnorr signature value B, in hex representation.

aGVB

Schnorr signature value g^vb (vb is a random value), in hex representation.

aRB

Schnorr signature value rb = vb - xb * h, in hex representation.

aHkdfInfo

Missing Description

aAES256Key

The AES 256 encryption key, in base64 representation.

aHMAC256Key

The 256 bit HMAC key, in base64 representation.

Parameters

aSignerID

String identifying the signer.

aGX1

Schnorr signature value g^x1, in hex representation.

aGV1

Schnorr signature value g^v1 (v1 is a random value), in hex representation.

aR1

Schnorr signature value r1 = v1 - x1 * h, in hex representation.

Schnorr signature value g^x2, in hex representation.

aGV2

Schnorr signature value g^v2 (v2 is a random value), in hex representation.

aR2

Schnorr signature value r2 = v2 - x2 * h, in hex representation.
