The Swift types keep the HashType shape and buffer their input, so the streaming call sites in ProgramDerivedAccount and ConversationID+TipDm are untouched; the shared side hashes once at digestBytes(). The HMAC and PBKDF Algorithm enums narrow to what the shared facade offers -- HMAC to sha256/sha512, PBKDF to sha512. Nothing outside the enum declarations used sha1/sha224/sha384, and the only caller of PBKDF .sha256 was a test asserting the digest length of a path with no production caller, so it goes with the case. 850 FlipcashCore tests pass, and the 6 FlipcashCoreVectors fixtures still match -- Slip10DerivationVectorTests runs BIP39 and SLIP-0010 through the new PBKDF2-SHA512 and HMAC-SHA512. --- .../Sources/FlipcashCore/Hashes/HMAC.swift | 69 ++++++------------- .../Sources/FlipcashCore/Hashes/PBKDF.swift | 61 ++++------------ .../Sources/FlipcashCore/Hashes/SHA256.swift | 33 ++++----- .../Sources/FlipcashCore/Hashes/SHA512.swift | 29 +++----- .../Tests/FlipcashCoreTests/PBKDFTests.swift | 6 -- 5 files changed, 61 insertions(+), 137 deletions(-) diff --git a/FlipcashCore/Sources/FlipcashCore/Hashes/HMAC.swift b/FlipcashCore/Sources/FlipcashCore/Hashes/HMAC.swift index 6f9a3656f..76c8afee6 100644 --- a/FlipcashCore/Sources/FlipcashCore/Hashes/HMAC.swift +++ b/FlipcashCore/Sources/FlipcashCore/Hashes/HMAC.swift @@ -7,41 +7,37 @@ // import Foundation -import CommonCrypto +import SharedCoreKit +/// HMAC, computed by the shared Kotlin implementation.

KeyPair keeps every public signature, so the derivation and signing call sites are untouched. Seed generation moves to SecRandomCopyBytes: the shared module excludes seed.c on purpose, since it takes a caller-supplied seed rather than reaching for platform entropy. generate() still returns nil on failure rather than trapping, matching what the C entry point reported through its status code. CrossPlatformVectors moves onto SharedCoreKit with it, which means it moves off the macOS host -- the XCFramework ships iOS slices only. Running it on a simulator is what the gate is for now: it exercises the framework as FlipcashCore consumes it, which the Kotlin-side Ed25519VectorTest on the same fixtures does not. 850 FlipcashCore tests, 6 FlipcashCoreVectors fixtures, and the ed25519 vector all pass. --- .github/workflows/vectors.yml | 27 +- Code.xcodeproj/project.pbxproj | 2 - CodeCurves/.gitignore | 8 - CodeCurves/Package.swift | 23 - CodeCurves/Sources/CodeCurves/add_scalar.c | 69 - CodeCurves/Sources/CodeCurves/ed25519.h | 40 - CodeCurves/Sources/CodeCurves/fe.c | 1491 ----------------- CodeCurves/Sources/CodeCurves/fe.h | 41 - CodeCurves/Sources/CodeCurves/fixedint.h | 72 - CodeCurves/Sources/CodeCurves/ge.c | 467 ------ CodeCurves/Sources/CodeCurves/ge.h | 74 - .../Sources/CodeCurves/include/ed25519.h | 40 - CodeCurves/Sources/CodeCurves/key_exchange.c | 79 - CodeCurves/Sources/CodeCurves/keypair.c | 16 - CodeCurves/Sources/CodeCurves/precomp_data.h | 1391 --------------- CodeCurves/Sources/CodeCurves/sc.c | 809 --------- CodeCurves/Sources/CodeCurves/sc.h | 12 - CodeCurves/Sources/CodeCurves/seed.c | 68 - CodeCurves/Sources/CodeCurves/sha512.c | 275 --- CodeCurves/Sources/CodeCurves/sha512.h | 21 - CodeCurves/Sources/CodeCurves/sign.c | 31 - CodeCurves/Sources/CodeCurves/verify.c | 85 - CrossPlatformVectors/Package.swift | 19 +- .../Ed25519VectorTests.swift | 38 +- FlipcashCore/Package.swift | 4 +- .../FlipcashCore/Solana/Keys/Derive.swift | 1 - .../Solana/Keys/Key+Generate.swift | 36 +- .../FlipcashCore/Solana/Keys/KeyPair.swift | 68 +- 28 files changed, 94 insertions(+), 5213 deletions(-) delete mode 100644 CodeCurves/.gitignore delete mode 100644 CodeCurves/Package.swift delete mode 100755 CodeCurves/Sources/CodeCurves/add_scalar.c delete mode 100755 CodeCurves/Sources/CodeCurves/ed25519.h delete mode 100755 CodeCurves/Sources/CodeCurves/fe.c delete mode 100755 CodeCurves/Sources/CodeCurves/fe.h delete mode 100755 CodeCurves/Sources/CodeCurves/fixedint.h delete mode 100755 CodeCurves/Sources/CodeCurves/ge.c delete mode 100755 CodeCurves/Sources/CodeCurves/ge.h delete mode 100755 CodeCurves/Sources/CodeCurves/include/ed25519.h delete mode 100755 CodeCurves/Sources/CodeCurves/key_exchange.c delete mode 100755 CodeCurves/Sources/CodeCurves/keypair.c delete mode 100755 CodeCurves/Sources/CodeCurves/precomp_data.h delete mode 100755 CodeCurves/Sources/CodeCurves/sc.c delete mode 100755 CodeCurves/Sources/CodeCurves/sc.h delete mode 100755 CodeCurves/Sources/CodeCurves/seed.c delete mode 100755 CodeCurves/Sources/CodeCurves/sha512.c delete mode 100755 CodeCurves/Sources/CodeCurves/sha512.h delete mode 100755 CodeCurves/Sources/CodeCurves/sign.c delete mode 100755 CodeCurves/Sources/CodeCurves/verify.c diff --git a/.github/workflows/vectors.yml b/.github/workflows/vectors.yml index b82fe1c44..611edf4ab 100644 --- a/.github/workflows/vectors.yml +++ b/.github/workflows/vectors.yml @@ -5,9 +5,10 @@ name: Cross-platform vector gate # two apps compute keys, signatures, and on-chain amounts in parallel Swift and # Kotlin implementations; these vectors are what keeps the answers identical. # -# Two packages because they cannot share a deployment target: CodeCurves is -# plain C and builds for the host, while FlipcashCore declares only iOS and its -# transitive deps (BigDecimal, grpc/nio) will not resolve for a macOS build. +# Two packages because they cannot share a deployment target: FlipcashCore's +# transitive deps (BigDecimal, grpc/nio) pull a macOS floor that CrossPlatformVectors +# does not want.

Point all four manifests (FlipcashCore, FlipcashUI, CrossPlatformVectors, Code.xcodeproj) back at the published flipcash-shared-core-spm 0.4.0, which carries them. Verified against the real published framework, not the local override: FlipcashCore (850/850), CrossPlatformVectors (1/1), and FlipcashCoreVectors (6/6) all pass on an iOS Simulator.
