From 19697c6e9244fe8478c7f2a3cf8e49b5d33746ac Mon Sep 17 00:00:00 2001 From: Tony Arcieri Date: Fri, 26 Jul 2024 08:49:47 -0600 Subject: [PATCH] Fix missing features found by Rust 1.80 Some crates were defining features but not using them: - bign256: added `bits`, `serde`, `test-vectors` features - p521: removed `bits` vestiges (too hard with weird modulus size) - sm2: added `bits` feature In fixing this, I also uncovered that bign256's test vectors are failing. --- bign256/Cargo.toml | 20 +++++++++++------- bign256/src/arithmetic/scalar.rs | 3 --- bign256/src/lib.rs | 2 +- bign256/tests/projective.rs | 36 ++++++++++++++++++-------------- p521/src/arithmetic/scalar.rs | 16 -------------- sm2/Cargo.toml | 1 + sm2/src/lib.rs | 2 +- 7 files changed, 35 insertions(+), 45 deletions(-) diff --git a/bign256/Cargo.toml b/bign256/Cargo.toml index 54c1af92..e3a0c846 100644 --- a/bign256/Cargo.toml +++ b/bign256/Cargo.toml @@ -21,22 +21,23 @@ rust-version = "1.73" elliptic-curve = { version = "=0.14.0-pre.5", features = ["hazmat", "sec1"] } # optional dependencies -primeorder = { version = "=0.14.0-pre.0", optional = true, path = "../primeorder" } -signature = { version = "=2.3.0-pre.3", optional = true } belt-hash = { version = "=0.2.0-pre.3", optional = true, default-features = false } -rfc6979 = { version = "=0.5.0-pre.3", optional = true } -rand_core = "0.6.4" -pkcs8 = { version = "0.11.0-pre.0", optional = true } -sec1 = { version = "0.8.0-pre.1", optional = true } der = { version = "0.8.0-pre.0" } - digest = { version = "0.11.0-pre.8", optional = true } +hex-literal = { version = "0.4", optional = true } hkdf = { version = "0.13.0-pre.3", optional = true } hmac = { version = "0.13.0-pre.3", optional = true } +rand_core = "0.6.4" +rfc6979 = { version = "=0.5.0-pre.3", optional = true } +pkcs8 = { version = "0.11.0-pre.0", optional = true } +primeorder = { version = "=0.14.0-pre.0", optional = true, path = "../primeorder" } +sec1 = { version = "0.8.0-pre.1", optional = true } +signature = { version = "=2.3.0-pre.3", optional = true } [dev-dependencies] criterion = "0.5" hex-literal = "0.4" +primeorder = { version = "=0.14.0-pre.0", features = ["dev"], path = "../primeorder" } proptest = "1" rand_core = { version = "0.6", features = ["getrandom"] } hex = { version = "0.4" } @@ -46,11 +47,14 @@ default = ["arithmetic", "pkcs8", "std", "ecdsa", "pem", "ecdh"] alloc = ["elliptic-curve/alloc", "primeorder?/alloc"] std = ["alloc", "elliptic-curve/std", "signature?/std"] -ecdsa = ["arithmetic", "dep:rfc6979", "dep:signature", "dep:belt-hash"] arithmetic = ["dep:primeorder", "elliptic-curve/arithmetic"] +bits = ["arithmetic", "elliptic-curve/bits"] +ecdsa = ["arithmetic", "dep:rfc6979", "dep:signature", "dep:belt-hash"] pem = ["pkcs8", "sec1/pem"] pkcs8 = ["dep:pkcs8"] ecdh = ["arithmetic", "elliptic-curve/ecdh", "dep:digest", "dep:hkdf", "dep:hmac", "dep:belt-hash", "alloc"] +serde = ["elliptic-curve/serde", "primeorder?/serde"] +test-vectors = ["dep:hex-literal"] [[bench]] name = "field" diff --git a/bign256/src/arithmetic/scalar.rs b/bign256/src/arithmetic/scalar.rs index 340f5169..3d2d9122 100644 --- a/bign256/src/arithmetic/scalar.rs +++ b/bign256/src/arithmetic/scalar.rs @@ -33,9 +33,6 @@ use primeorder::impl_bernstein_yang_invert;
