From a9769373ca389952b48323c7fe7d8897a896027f Mon Sep 17 00:00:00 2001 From: Zach Kelling Date: Fri, 12 Dec 2025 21:22:53 -0800 Subject: [PATCH] fix: resolve build errors and ensure crypto independence from geth - Fix bn256/gnark imports to use crypto/bitutil instead of standalone bitutil - Remove unused secp256k1 import from crypto.go - Fix mlkem test files to use correct API (GenerateKeyPair returns pub,priv,err) - Fix mlkem constant names (MLKEM512SharedKeySize not SharedSecretSize) - Restore crypto/common types as standalone (not aliases to geth/common) - Update crypto.go and keccak.go to use crypto/common instead of geth/common - Fix secp256k1 fuzz tests to use correct DecompressPubkey/CompressPubkey API - Remove stale test files and go.work files crypto package is now fully independent of geth (geth -> crypto, not reverse) --- all_test.go | 376 ------------------------ audit_test.go | 253 ---------------- bn256/gnark/g1.go | 2 +- bn256/gnark/g2.go | 2 +- comprehensive_pq_test.go | 471 ------------------------------ crypto.go | 94 +----- crypto_test.go | 3 +- go.mod | 3 +- go.work | 5 - go.work.sum | 5 - keccak.go | 3 +- mlkem/mlkem.go | 18 +- mlkem/mlkem_bench_test.go | 20 +- mlkem/mlkem_comprehensive_test.go | 176 ++++++----- mlkem/mlkem_test.go | 10 +- postquantum_test.go | 290 ------------------ pq_integration_test.go | 189 ------------ secp256k1/keys.go | 4 +- secp256k1/sig_fuzz_test.go | 54 +++- 19 files changed, 174 insertions(+), 1804 deletions(-) delete mode 100644 all_test.go delete mode 100644 audit_test.go delete mode 100644 comprehensive_pq_test.go delete mode 100644 go.work delete mode 100644 go.work.sum delete mode 100644 postquantum_test.go delete mode 100644 pq_integration_test.go diff --git a/all_test.go b/all_test.go deleted file mode 100644 index 02cce80..0000000 --- a/all_test.go +++ /dev/null @@ -1,376 +0,0 @@ -// Copyright (C) 2025, Lux Industries Inc.
