admin 9bf56a806b Move docs/ package mirror into document-navigator plugin 
Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

Raw Blame History

@suaveplan/crypto-rsa - RSA primitives — RFC 8017 PKCS #1 v2.2, RFC 5208 PKCS #8, RFC 5280 SPKI, RFC 7517/7518 JWK, RFC 7468 PEM. Universal; ships ASN.1/DER, key parse/serialise across PKCS#1/SPKI/PKCS#8/JWK/PEM, modulus-length policy, modular-arithmetic primitives, and the error/observability registry.

Summary

RSA primitives for Suaveplan — RFC 8017 PKCS #1 v2.2, RFC 5208 / RFC 5958 PKCS #8, RFC 5280 SPKI, RFC 7517 / RFC 7518 JWK, RFC 7468 PEM. Universal package (zero browser/React dependencies, runs anywhere ES2022 + BigInt + crypto.subtle or a @noble/curves-compatible engine is available).

This package is shipped in stages. Stage 1 (this release) provides every primitive a sign/verify/encrypt/decrypt pipeline depends on: ASN.1 / DER reader and writer, key parsing and serialisation across all five formats, modulus-length policy enforcement, modular-arithmetic primitives (modPow, i2osp, os2ip, CRT private operation), PEM textual encoding, and the full error / observability registry. Stages 2-4 will land the encoding methods (MGF1 + EMSA-PKCS1-v1_5 + EMSA-PSS), the sign / verify / encrypt / decrypt / key-generation entry points, the engine adapter (@noble/curves

  • WebCrypto subtle), and the FIPS / JWK / blinding / fingerprint surface.

bun add @suaveplan/crypto-rsa

Quick start — parse and serialise

import {
    parseRsaPublicKey,
    parseRsaPublicKeyPem,
    serializeRsaPublicKey,
    serializeRsaPublicKeyPem,
} from "@suaveplan/crypto-rsa";

// PEM in, PEM out (round-trip).
const key = parseRsaPublicKeyPem(spkiPemString);
const back = serializeRsaPublicKeyPem(key); // -----BEGIN PUBLIC KEY-----…

// DER + JWK round-trips.
const der = serializeRsaPublicKey(key, { format: "spki" });
const jwk = serializeRsaPublicKey(key, { format: "jwk" });
const fromDer = parseRsaPublicKey(der as Uint8Array, { format: "spki" });
const fromJwk = parseRsaPublicKey(jwk, { format: "jwk" });

Quick start — modulus policy

import { enforceMaxBitLength, enforceMinBitLength } from "@suaveplan/crypto-rsa/policy";

enforceMinBitLength(publicKey); // throws if < 2048 bits
enforceMinBitLength(legacyKey, { allowLegacy: true }); // accepts ≥ 1024 bits
enforceMaxBitLength(publicKey); // throws if > 16384 bits

Quick start — math primitives

import {
    modPow,
    i2osp,
    os2ip,
    rsaPrivateOperationCrt,
} from "@suaveplan/crypto-rsa/math";

const c = os2ip(ciphertext);
const m = rsaPrivateOperationCrt(c, privateKey); // CRT-aware private op
const plaintext = i2osp(m, ciphertext.length);
const v = modPow(c, publicKey.e, publicKey.n); // public op

Stage roadmap

  • Stage 1: ASN.1 / DER, key parse + serialise (PKCS#1, SPKI, PKCS#8, JWK, PEM), modulus-length policy, math primitives, full error / observability registry.
  • Stage 2: MGF1, EMSA-PKCS1-v1_5, EMSA-PSS, sign / verify (RSASSA-PKCS1-v1_5 + PSS).
  • Stage 3: encrypt / decrypt (PKCS#1 v1.5 + OAEP), key generation (Miller-Rabin, multi-prime), blinding (RFC 8017 §5.1.2 / Kocher 1996).
  • Stage 4 (this release): blinding wired into sign paths, JWK thumbprint (RFC 7638)
    • thumbprint URI (RFC 9278), SPKI fingerprint with four output formats, RsaCryptoEngine adapter (noble + WebCrypto subtle + auto-selector), RsaKeyHandle HSM bridge with reference SoftwareRsaKeyHandleProvider, FIPS 186-5 profile, JWK key_ops / use / alg enforcement.
