org.bouncycastle.crypto.hash2curve.test.BLS12_381G2HashToCurveTest

All Implemented Interfaces:

junit.framework.Test

public class BLS12_381G2HashToCurveTest
extends junit.framework.TestCase

Known-answer tests for BLS12381G2_XMD:SHA-256_SSWU_RO_ from RFC 9380 Appendix J.10.1. Each vector checks intermediate layers (u[0], u[1], Q0, Q1) before the final hashed point P, so a regression localises to the specific stage that broke.
