It serves as a reference for understanding library choices, implementation patterns, and maintenance of cryptographic operations. + +## Library Choices + +The following libraries were selected for specific cryptographic operations. These decisions prioritize compatibility with the existing CyberChef API surface and cryptographic correctness. + +### ECDSA: `@noble/curves` + +Uses `@noble/curves` with `@noble/hashes/legacy` for MD5/SHA-1 digests. + +**Why not Web Crypto?** The Web Crypto API refuses MD5 and SHA-1 digests, which the CyberChef UI exposes to users. `@noble/curves` with legacy hash support maintains this functionality. + +### X.509 / CSR / CRL: `@peculiar/x509` + +Uses `@peculiar/x509` for certificate, CSR, and CRL parsing and generation, with `@peculiar/asn1-*` schema packages as needed. + +**Version pin:** Keep `@peculiar/x509` on the `1.14.x` line. + +**Why pinned?** `@peculiar/x509` v2 requires a `reflect-metadata` polyfill/import at each runtime entry point. CyberChef currently avoids that cross-bundle polyfill cost and complexity, so v1 remains the project baseline unless that tradeoff is revisited. + +**Why not pkijs?** `@peculiar/x509` offers a cleaner API better suited to CyberChef's operation model. + +### SM2: `@noble/curves/sm2` + +Uses the SM2 implementation from `@noble/curves`. + +**Why not sm-crypto?** `@noble/curves` provides a reliable, actively maintained SM2 implementation. + +### DSA: `node-forge` + +The `PubKeyFromPrivKey` operation continues to use `node-forge` for DSA key generation. + +**Why?** `node-forge` is already a project dependency, and DSA is a single, localized operation not worth introducing a new library for. + +### Generic ASN.1 Dump: `asn1js` + +Uses `asn1js` for generic ASN.1 hex structure dumping. + +**Note:** This is a transitive dependency of `@peculiar/x509` and requires no additional imports for most use cases. + +## Coding Conventions + +These conventions ensure consistency across cryptographic operations and maintain compatibility with existing test fixtures. + +### PEM Line Endings + +Use `\n` only for PEM-encoded output. Do not use `\r\n`. + +The legacy `jsrsasign` output used `\r\n` in some cases. All test fixtures have been updated to expect `\n` exclusively. + +### Hex Coordinate Padding + +When converting elliptic curve point coordinates from `bigint` to hex: + +- **P-256 and SM2:** Use `.padStart(64, "0")` (32 bytes = 64 hex characters) +- **P-521:** Use `.padStart(132, "0")` (66 bytes = 132 hex characters) + +Apply this after calling `bigint.toString(16)`. + +### JWK Field Ordering + +Build JWK objects using literal syntax in this exact order so `JSON.stringify` emits fields in the correct sequence: + +**Elliptic Curve:** +```javascript +{ kty, crv, x, y, d? } +``` + +**RSA:** +```javascript +{ kty, n, e, d?, p?, q?, dp?, dq?, qi? } +``` + +JavaScript preserves insertion order for object properties, and downstream consumers may depend on this ordering. + +### ECDSA r/s Leading-Zero Quirk + +The `parseSigHexInHexRS` function historically prepends `00` to the r or s component when its most significant bit is set. This is a quirk from DER 2's-complement encoding. + +**Replicate this behavior.** Existing test fixtures depend on it, and changing it breaks compatibility. + +### RFC 6979 Determinism + +ECDSA signature outputs from `@noble/curves` *should* match `jsrsasign` byte-for-byte when using the same curve and digest algorithm. + +**If they diverge:** The signature is still cryptographically valid. Update the test fixture and document the divergence in the changelog. Do not attempt to massage the library output to force a match. + +### Golden Output Cosmetic Drift + +For text-based operations that dump parsed structures (`ParseX509Certificate`, `ParseCSR`, `ParseX509CRL`, `ParseASN1HexString`), minor formatting differences between `jsrsasign` and the new implementation are acceptable. + +**Action:** Update the test fixture and note the change in the changelog. + +### Cryptographic Correctness is Non-Negotiable + +Fixture data that exercises actual cryptographic operations (e.g., SM2 ciphertext→plaintext transformations in [tests/operations/tests/SM2.mjs](tests/operations/tests/SM2.mjs)) must pass unchanged. These fixtures pin real cryptographic behavior and cannot be updated cosmetically. + +## Shared Helper Modules + +To avoid duplicating logic across operations, use these utility modules: + +### [src/core/lib/Asn1.mjs](src/core/lib/Asn1.mjs) + +ASN.1 utilities for OID and DER manipulation: +- `oidHexToInt()` — convert ASN.1 OID hex encoding to integer dotted notation +- `oidIntToHex()` — convert integer dotted notation to ASN.1 OID hex +- `derToPem()` — wrap DER bytes in PEM format +- `dumpAsn1Hex()` — generic ASN.1 hex structure dump (uses `asn1js`) + +### [src/core/lib/Ecdsa.mjs](src/core/lib/Ecdsa.mjs) + +ECDSA operations with `@noble/curves`: +- `loadEcKey()` — parse EC private/public keys from PEM or JWK +- `signEcdsa()` — sign data with an EC private key +- `verifyEcdsa()` — verify an ECDSA signature +- Signature format converters (ASN.1 DER ↔ r/s hex format) +- `isAsn1Hex()` — detect ASN.1 DER-encoded data +- `generateEcKeyPair()` — generate a new EC key pair + +### [src/core/lib/PublicKey.mjs](src/core/lib/PublicKey.mjs) + +Public key utilities and DN formatting.

A short comment above each `ED*_PUBKEY` constant records the verification so the fixtures aren't read as circular snapshots of `@peculiar/x509`'s own output. +- **[tests/node/tests/nodeApi.mjs](tests/node/tests/nodeApi.mjs) recipe-format tests no longer feed `Hex to PEM` garbage.** The three `chef.bake` tests previously piped Morse-coded output (dashes/dots) through `Hex to PEM`, which is the reason PR 1 made `derToPem` lenient about non-hex input. They now use `To Hex` → `Hex to PEM` → `To Snake case` and produce well-formed PEM of `"some input"`.

[src/core/lib/PublicKey.mjs](src/core/lib/PublicKey.mjs)'s `formatDnObj` now accepts both the legacy jsrsasign shape and `@peculiar/x509`'s `JsonName` (array-of-records) shape. Migrated ops: [ParseX509Certificate.mjs](src/core/operations/ParseX509Certificate.mjs), [PubKeyFromCert.mjs](src/core/operations/PubKeyFromCert.mjs), [ParseCSR.mjs](src/core/operations/ParseCSR.mjs), [ParseX509CRL.mjs](src/core/operations/ParseX509CRL.mjs). +- **`X509Certificate` v1.14.3 doesn't expose `.version`.** Plan called for `cert.version`, but on the pinned v1 the property is missing. Worked around by parsing `cert.rawData` with the asn1-x509 `Certificate` schema and reading `tbsCertificate.version` + `signatureAlgorithm.algorithm` directly. The same approach is used in `ParseCSR` (with `CertificationRequest` from `@peculiar/asn1-csr`) and `ParseX509CRL` (with `CertificateList` from `@peculiar/asn1-x509`) — bypassing the WebCrypto algorithm mapping is necessary for DSA anyway (peculiar's algorithm provider doesn't know it). +- **DSA bit-length now matches OpenSSL/jsrsasign output.** `describeSpki` strips the leading `00` byte from the DSS-Parms `p` INTEGER before computing the bit length, so `Length: 2048 bits` is reported rather than the 2056 the raw byte count would give. +- **P-521 reports `Length: 521 bits`**, not 528. `EC_CURVE_OID_TO_NAMES` carries an explicit `bits` field per curve so the prime field size (rather than `byteLen * 8`) is reported. +- **KeyUsage rendering order.** `KeyUsage.toJSON()` on the asn1-x509 wrapper returns the flag names in alphabetical order (`crlSign`, `dataEncipherment`, …); the existing CSR golden fixtures expect bit-position order (`digitalSignature`, `nonRepudiation`, `keyEncipherment`, …). The op now parses the BIT STRING and iterates the bits in order so the output is stable. +- **`Public Key from Certificate` now works for Ed25519 / Ed448.** jsrsasign threw "Unsupported public key type"; `@peculiar/x509`'s `cert.publicKey.toString("pem")` handles both. Updated [tests/operations/tests/PubKeyFromCert.mjs](tests/operations/tests/PubKeyFromCert.mjs) — the previously-commented `ED25519_PUBKEY` / `ED448_PUBKEY` constants are live and the two negative test expectations were replaced with the actual PEMs. +- **PEM line endings switched from `\r\n` to `\n` everywhere** (per the cross-PR convention in [AGENTS.md](AGENTS.md)). [tests/operations/tests/PubKeyFromCert.mjs](tests/operations/tests/PubKeyFromCert.mjs) loses its `.replace(/\r/g, "").replace(/\n/g, "\r\n")` post-processing. +- **OtherName payload is parsed loosely.** The legacy `ParseCSR` fixture for `Other: 1.2.3.4::some value` requires extracting a UTF8String wrapped in the ANY-typed `value` field. `formatGeneralName` first tries to parse it as a primitive `UTF8String`/`BmpString`/`PrintableString`/`IA5String`, then falls back to `DirectoryString`, and finally to a hex dump. Same code path serves the CRL OtherName output (with `OtherName:` label, no space — per the CRL flavor) and the CSR/Cert SAN output (`Other: ` label, with space — per the CSR flavor). +- **`ParseX509Certificate` no longer relies on `cert.getInfo()` string-splitting.** The legacy code grabbed the extensions block by splitting on hard-coded delimiters. Replaced with a real walker over `cert.extensions` that recognises BasicConstraints, KeyUsage, EKU, SAN, AKI, SKI, CRLDistributionPoints, IssuerAltName; everything else falls back to `:` + raw hex. +- **Cosmetic drift in the `Certificate Signature` block for ECDSA certs.** The old code split the DER signature with hard-coded offsets (`r.ASN1HEX.getV(sig, 4)` and `getV(sig, 48)`), which only worked for 32-byte components and produced visibly-overlapping output otherwise. The new code uses the proper DER parser. The output difference is a *correction*, not a regression — but it's still drift, and means the `ParseX509Certificate` golden output now reflects the true r/s values. +- **New regression coverage for `ParseX509Certificate`.** [tests/operations/tests/ParseX509Certificate.mjs](tests/operations/tests/ParseX509Certificate.mjs) carries golden output for an RSA cert and a P-256 cert (reusing the certs from [PubKeyFromCert.mjs](tests/operations/tests/PubKeyFromCert.mjs)), plus an empty-input test. Wired into [tests/operations/index.mjs](tests/operations/index.mjs). +- No new dependencies — everything reuses what PR 1 already pinned. + +### PR 4 — 2026-05-17 +- New [src/core/lib/KeyConvert.mjs](src/core/lib/KeyConvert.mjs) holds the shared RSA/EC/DSA conversion helpers (`parseKeyPem`, `parseCertPublicKey`, `keyToJwk`, `keyFromJwk`, `keyInfoToPem`, `derivePublicKeyInfo`). Plan called for inlining helpers per-op; factoring them out avoided duplicating the RSA SPKI/PKCS#8 plumbing between [PEMToJWK.mjs](src/core/operations/PEMToJWK.mjs), [JWKToPem.mjs](src/core/operations/JWKToPem.mjs) and [PubKeyFromPrivKey.mjs](src/core/operations/PubKeyFromPrivKey.mjs). +- **node-forge dropped from the migration.** The plan reserved node-forge for the DSA path in `PubKeyFromPrivKey`, but `node-forge` only ships RSA support in its `pki` module — no DSA parser/serialiser. DSA traditional `-----BEGIN DSA PRIVATE KEY-----` is parsed via `asn1js.fromBER` directly, and the SPKI is built via `new asn1js.Sequence({value: [new Integer(...), ...]}).toBER(false)`. No new dependency. +- **RSA PEMs go through `@peculiar/asn1-rsa` schemas** (`RSAPrivateKey`, `RSAPublicKey`) plus the existing `PrivateKeyInfo` / `SubjectPublicKeyInfo` / `AlgorithmIdentifier` schemas. `id_rsaEncryption` is namespace-imported (`import * as rsaSchemas from "@peculiar/asn1-rsa"`) and aliased to `ID_RSA_ENCRYPTION` to dodge the ESLint `camelcase` rule, matching the convention PR 3 established for the EC OID constants. +- **DER `00`/INTEGER plumbing.** Parsed INTEGER fields come out of asn1js with the DER 2's-complement leading `00` still present; `stripLeadingZero` removes it for JWK output. On the way back the helper `prefixForDerInt` re-adds the `00` byte when the magnitude's MSB is set so the serialised INTEGER stays positive. JWK base64url is hand-rolled (no padding) — `toBase64(..., "A-Za-z0-9-_")` in `Base64.mjs` requires going through `Utils.strToArrayBuffer` for string inputs, which would double-encode the bytes for non-ASCII content. +- **PEM line endings switched from `\r\n` to `\n`** in the test fixtures for [tests/operations/tests/JWK.mjs](tests/operations/tests/JWK.mjs) and [tests/operations/tests/PubKeyFromPrivKey.mjs](tests/operations/tests/PubKeyFromPrivKey.mjs), per the cross-PR convention in [AGENTS.md](AGENTS.md). The fixtures previously did `.replace(/\n/g, "\r\n")` around every expected PEM; those are gone now. +- **Ed25519/Ed448 error-message drift.** PubKeyFromPrivKey's "Unsupported key type" wrapper used to surface jsrsasign's `Error: malformed PKCS8 private key(code:004)`; with the EC parser now coming from `@peculiar/asn1-ecc` + `loadEcKey`, the inner error is the `OperationError("Provided key is not an EC key.")` raised inside [src/core/lib/Ecdsa.mjs](src/core/lib/Ecdsa.mjs). Updated the two `Ed25519` / `Ed448` test fixtures to expect the new message (`Unsupported key type: Error: Provided key is not an EC key.` — `OperationError`'s name field is `Error`, hence the `Error:` prefix). +- **`Unsupported JWK key type` error now references `jwk.kty`** rather than the top-level `inputJson.kty`. The legacy op compared against `jwk.kty` but reported `inputJson.kty`, which was undefined for JWK Set / array inputs. Existing test passes either way because it uses a single-key OKP input. +- No new dependencies; relies on the deps PR 1 already pinned (`@peculiar/asn1-rsa` etc. ship with `@peculiar/x509`). + +### PR 3 — 2026-05-17 +- New [src/core/lib/Ecdsa.mjs](src/core/lib/Ecdsa.mjs) replaces the jsrsasign calls in [ECDSASign.mjs](src/core/operations/ECDSASign.mjs), [ECDSAVerify.mjs](src/core/operations/ECDSAVerify.mjs), [ECDSASignatureConversion.mjs](src/core/operations/ECDSASignatureConversion.mjs) and [GenerateECDSAKeyPair.mjs](src/core/operations/GenerateECDSAKeyPair.mjs). `loadEcKey` handles SEC1, PKCS#8 and SPKI PEMs by parsing them with `@peculiar/asn1-ecc` / `@peculiar/asn1-pkcs8` / `@peculiar/asn1-x509`. ECDSA itself is `@noble/curves`'s `p256` / `p384` / `p521` with explicit `{ prehash: false, lowS: false, format: "der" }` — see notes below. +- **`lowS: false` on both sign and verify.** Noble defaults to `lowS: true` (BTC/ETH-style malleability rejection), which (a) would normalise produced signatures and could diverge from jsrsasign byte-for-byte, and (b) would reject existing jsrsasign-produced signatures whose `s` happened to be in the upper half. We disable lowS to preserve interoperability with the existing fixtures. +- **`prehash: false`.** The operation hashes the message itself (so MD5/SHA-1 work via `@noble/hashes/legacy`); noble would otherwise re-hash with the curve's default digest. The Sign/Verify operations call `digestBytes(...)` and pass the digest in directly. +- **Latin-1 truncation for string→bytes.** Both Sign (input string) and Verify (`Utils.convertToByteString(msg, "Raw")` → string) follow what jsrsasign did under the hood: each JS code unit is masked to its low byte. That's wrong for free-text UTF-8 but matches the existing behaviour and is what the round-trip tests assume. Encoded as `strToBytesLatin1` in `Ecdsa.mjs`. +- **`parseAsn1SigToHexRS` keeps the DER `00` prefix.** The jsrsasign helper returned r/s as the raw INTEGER bytes (so a 32-byte r whose MSB was set came back as 33 hex bytes starting with `00`). The Raw JSON test fixture in [tests/operations/tests/ECDSA.mjs](tests/operations/tests/ECDSA.mjs) depends on that. Replicated with an inline DER reader rather than going through `bigint` (which would strip the leading zero). +- **No fixture changes.** All 83 ECDSA tests pass unchanged: deterministic-k sign↔verify cycles, the canned P-256 SHA-256 ASN.1/P1363/JWS/JSON inputs, and the negative tests (RSA key rejected, private-where-public expected, JSON missing r/s, etc.). The Generate ECDSA Key Pair op has no fixtures; manually exercised PEM/DER/JWK output paths. +- `id_*` OID constants from `@peculiar/asn1-ecc` are namespace-imported and re-aliased to SCREAMING_SNAKE locals because ESLint's `camelcase` rule trips on the snake_case export names. + +### PR 2 — 2026-05-17 +- `@noble/curves` v2 has no `/sm2` subpath, so [src/core/lib/SM2.mjs](src/core/lib/SM2.mjs) builds the curve itself with `weierstrass(...)` from `@noble/curves/abstract/weierstrass.js` using the GM/T 0003-2012 parameter set. Curve constructor is memoised per name so repeated `new SM2(...)` calls don't rebuild it. +- Random `k` generation: `ecdh(Point).utils.randomSecretKey()` → `bytesToNumberBE(...) % (n-1n) + 1n`, which mirrors the `[1, n-1]` distribution of the old `r.SecureRandom`-backed `getBigRandom`. The plan suggested `sm2.utils.randomPrivateKey()` directly; the abstract-Weierstrass path needs the explicit `bytes → bigint mod` step because the curve isn't pre-wrapped. +- `Point.fromHex("04" + x + y)` validates that the coords lie on the curve and raises before `is0()` can ever run; the explicit infinity check is kept for symmetry with the previous code. Invalid-point errors are caught and rethrown as `OperationError` so user-facing error messages stay unchanged. +- Coord padding switched from `("0000000000" + ...).slice(-charlen)` to `.padStart(charlen, "0")` per the cross-PR convention in [AGENTS.md](AGENTS.md). Output hex layout is byte-identical to before (still 64-char fields for `sm2p256v1`). +- No fixture changes: [tests/operations/tests/SM2.mjs](tests/operations/tests/SM2.mjs) passes unchanged (the 4 hard-coded ciphertext→plaintext vectors plus the 4 encrypt→decrypt round-trips). + +### PR 1 — 2026-05-17 +- Pinned `@peculiar/x509` to `^1.14.3` instead of the latest (`2.x`). v2 hard-requires a `reflect-metadata` import at every entry point and the plan didn't budget for polyfilling every webpack chunk. Sticking with v1 keeps the bundle changes scoped to this PR. +- `@noble/curves` installed at `^2.2.0`. v2 no longer exports an `/sm2` subpath — see PR 2 note in "Notes for next session" above. +- `derToPem` was deliberately made lenient (whitespace stripped, odd length left-padded with `0`, non-hex chars treated as nibble `0`) to preserve the recipe-API tests that piped non-hex output from `To Morse Code` through `Hex to PEM`. The actual base64 emitted now follows standard byte-pair semantics, not jsrsasign's quirky `hex2b64` (3-hex-chars-→-2-base64-chars) layout — so the expected outputs in `tests/node/tests/nodeApi.mjs` for those recipe-format tests were regenerated. +- `dumpAsn1Hex` returns a plain `ASN.1 parse error: …` string when asn1js can't make sense of the input, rather than throwing. jsrsasign produced a best-effort `UNKNOWN() ` dump in this case; replicating that on asn1js would be a meaningful chunk of code and the operation has no automated-fixture exposure of the difference, so we accepted the drift. +- PEM line endings switched from `\r\n` to `\n` (per the cross-PR convention in [AGENTS.md](AGENTS.md)). Updated the `Hex to PEM` and `Parse ASN.1 hex string` golden tests in `tests/node/tests/operations.mjs`. +- New per-op fixture file [tests/operations/tests/ASN1.mjs](tests/operations/tests/ASN1.mjs) covers OID round-trips, the multi-byte OID arc edge case, PEM line wrapping, and basic ASN.1 dumps.
