From bfd5f1598cc462b460791fdfca9bb6c2c69fec9b Mon Sep 17 00:00:00 2001 From: Divy Srivastava Date: Sat, 6 Jan 2024 16:48:31 +0530 Subject: [PATCH] feat(ext/crypto): initial support for p521 in `generateKey` and `importKey` (#21815) Part 1 of a potential 3 part series. Ref #13449 The current implementation passes key material back and forth RustCrypto group of crates and ring. ring does not implement p521 yet. This PR adds support for P521 named curve in `generateKey` and `importKey` where we use RustCrypto. Other parts should be moved over to the RustGroup group of crates for consistency. --- Cargo.lock | 15 +++ cli/tests/unit/webcrypto_test.ts | 39 ++++++++ ext/crypto/00_crypto.js | 3 +- ext/crypto/Cargo.toml | 1 + ext/crypto/generate_key.rs | 8 +- ext/crypto/import_key.rs | 30 +++++- tools/wpt/expectation.json | 160 ++----------------------------- 7 files changed, 98 insertions(+), 158 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index f4f6c00609..fabd5ff62e 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1218,6 +1218,7 @@ dependencies = [ "once_cell", "p256", "p384", + "p521", "rand", "ring", "rsa", @@ -4115,6 +4116,20 @@ dependencies = [ "sha2", ] +[[package]] +name = "p521" +version = "0.13.3" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "0fc9e2161f1f215afdfce23677034ae137bbd45016a880c2eb3ba8eb95f085b2" +dependencies = [ + "base16ct", + "ecdsa", + "elliptic-curve", + "primeorder", + "rand_core", + "sha2", +] + [[package]] name = "parking_lot" version = "0.11.2" diff --git a/cli/tests/unit/webcrypto_test.ts b/cli/tests/unit/webcrypto_test.ts index 4e1a31eaac..829330eba8 100644 --- a/cli/tests/unit/webcrypto_test.ts +++ b/cli/tests/unit/webcrypto_test.ts @@ -2006,3 +2006,42 @@ Deno.test(async function testHmacJwkImport() { ["sign", "verify"], ); }); + +Deno.test(async function p521Import() { + const jwk = { + "crv": "P-521", + "ext": true, + "key_ops": [ + "verify", + ], + "kty": "EC", + "x": + "AXkSI8nfkc6bu3fifXGuKKbu08g5LKPfxUNQJJYzzPgmN8XLDzx0C9Sdeejl1XoWGrheKPHl0k4tUmHw0cdInpfj", + "y": + "AT4vjsO0bzVRlN3Wthv9DewncDXS2tlTob5QojV8WX1GzOAikRfWFEP3nspoSv88U447acZAsk5IvgGJuVjgMDlx", + }; + const algorithm = { name: "ECDSA", namedCurve: "P-521" }; + + const key = await crypto.subtle.importKey( + "jwk", + jwk, + algorithm, + true, + ["verify"], + ); + + assert(key instanceof CryptoKey); +}); + +Deno.test(async function p521Generate() { + const algorithm = { name: "ECDSA", namedCurve: "P-521" }; + + const key = await crypto.subtle.generateKey( + algorithm, + true, + ["sign", "verify"], + ); + + assert(key.privateKey instanceof CryptoKey); + assert(key.publicKey instanceof CryptoKey); +}); diff --git a/ext/crypto/00_crypto.js b/ext/crypto/00_crypto.js index 06dd0f41a6..d2949eb624 100644 --- a/ext/crypto/00_crypto.js +++ b/ext/crypto/00_crypto.js @@ -63,8 +63,7 @@ const { isDataView, } = core; -// P-521 is not yet supported. -const supportedNamedCurves = ["P-256", "P-384"]; +const supportedNamedCurves = ["P-256", "P-384", "P-521"]; const recognisedUsages = [ "encrypt", "decrypt", diff --git a/ext/crypto/Cargo.toml b/ext/crypto/Cargo.toml index 2ac35c4e00..9896bde0b3 100644 --- a/ext/crypto/Cargo.toml +++ b/ext/crypto/Cargo.toml @@ -30,6 +30,7 @@ num-traits = "0.2.14" once_cell.workspace = true p256 = { version = "0.13.2", features = ["ecdh"] } p384 = "0.13.0" +p521 = "0.13.3" rand.workspace = true ring = { workspace = true, features = ["std"] } rsa.workspace = true diff --git a/ext/crypto/generate_key.rs b/ext/crypto/generate_key.rs index 0745585324..43aea2c705 100644 --- a/ext/crypto/generate_key.rs +++ b/ext/crypto/generate_key.rs @@ -84,11 +84,17 @@ fn generate_key_rsa( Ok(private_key.as_bytes().to_vec()) } +fn generate_key_ec_p521() -> Vec { + let mut rng = OsRng; + let key = p521::SecretKey::random(&mut rng); + key.to_nonzero_scalar().to_bytes().to_vec() +} + fn generate_key_ec(named_curve: EcNamedCurve) -> Result, AnyError> { let curve = match named_curve { EcNamedCurve::P256 => &ring::signature::ECDSA_P256_SHA256_FIXED_SIGNING, EcNamedCurve::P384 => &ring::signature::ECDSA_P384_SHA384_FIXED_SIGNING, -
