[DotJs2024] Encrypt All Transports
In the shadowed corridors of digital discourse, where data streams pulse like vital arteries, lurks the imperative to cloak communications in unbreakable veils. Eleanor McHugh, a freelance reality consultant and anonymity architect with three decades spanning avionics to blockchain, issued this mandate at dotJS 2024. Ellie, co-founder of Innovative Identity Solutions, decried surveillance’s specter—from Lenovo’s BIOS interlopers to AI’s voracious scans—positing developers as privacy’s vanguard. Her whirlwind primer: wield WebSockets, RSA, AES in Node and browser crucibles, forging transports impervious to prying eyes.
Ellie’s ire ignited with 2015’s scandals: adware proxies hijacking HTTPS, unmasking “secure” flows for monetization. Today’s AI fervor—Facebook, Microsoft, Apple coveting content—echoes, demanding defiance. Privacy’s etymology—privity’s pact, NDA’s shroud—binds us; yet CTOs crave visibility, debugging APIs dissecting deeds at dawn’s witching hour. Ellie indicted: we, the coders, perpetuate panopticons, outsourcing souls to Albanian bunkers or quakesafe vaults. Reclamation resides in crypto’s toolkit: symmetric ciphers scrambling payloads, asymmetric duos authenticating origins, signatures vouching veracity, zero-knowledge veiling proofs.
Ellie’s arsenal gleams in GitHub’s forge: WebSockets for bidirectional brooks, RSA’s key pairs partitioning public probes from private vaults, AES randomizing streams into gibberish. Node’s crypto module, browser’s SubtleCrypto—both tame these titans. A vignette: socket spawns, keys exchanged via Diffie-Hellman ephemera, payloads AES-encrypted, RSA-signed—interception yields noise, replay thwarted by nonces. Zero-knowledge crowns: prove solvency sans balances, age sans birthdates—zk-SNARKs succinct, verifiable.
Ellie’s entreaty: tinker this trove, erect enclosures where client secrets elude server spies. As liveness biometrics and encrypted enclaves evolve, her free chapter beckons—crypto sans cost, privacy paramount. In software’s void, we architect anonymity; shirk not this solemnity.
Crypto Primitives in Play
Ellie enumerated: AES symmetrizes speed, RSA asymmetrizes trust—public encrypts, private decrypts. Signatures seal integrity; zk proofs affirm attributes incognito. WebSockets underpin, channels churning ciphered chatter—Node’s forge, browser’s bastion.
Defending Against Digital Dragnets
From BIOS betrayals to AI appetites, Ellie’s exposé exhorted: encrypt endpoints, anonymize identities. Her slides loop—3:30 eternities—urging uptake: GitHub’s gallery, SlideShare’s scrolls. Consultations await; privacy’s perimeter, we patrol.

[NodeCongress2021] The Security Toolbox For Node – Milecia McGregor
Fortifying Node.js bastions against pervasive threats demands a curated arsenal, blending vigilance with automation. Milecia McGregor, senior software engineer at Conducto, assembles this kit, dissecting OWASP’s top perils and arming attendees with battle-tested countermeasures. From dependency audits to server sentinels, her compendium ensures sprints proceed apace while vulnerabilities wane.
Milecia commences with reconnaissance: npm audit scans repos for exploits, flagging severity via exit codes integrable to CI. Snyk elevates this, fusing vuln databases with fix PRs, while Dependabot automates updates—proactive bulwarks against supply-chain snares like left-pad debacles.
Safeguarding Dependencies and Inputs
Injections top OWASP’s docket; Milecia prescribes parameterized queries via Knex or Sequelize, thwarting SQLi. XSS bows to sanitized outputs—DOMPurify scrubs payloads—while CSRF yields to csurf’s tokens. Auth falters sans salting; bcrypt hashes credentials, JWTs secure sessions with HS256.
Broken access? Role-based guards via Passport middleware enforce hierarchies. Sensitive leaks? dotenv .gitignore guards env vars; helmet configures headers, quelling MIME sniffing and clickjacking.
Validation anchors integrity: Joi schemas parse inputs, rejecting malformations; validator.js tackles emails, phones—eschewing bespoke parsers.
Encrypting Flows and Throttling Threats
Data en route merits crypto-js’s AES, obfuscating intercepts. Servers crave HTTPS—certbot automates Let’s Encrypt—rate-limit via express-rate-limit, capping barrages at 100/min/IP. DDoS? Cloudflare proxies absorb volleys.
Milecia extols reuse: helmet’s quick wins, Kali Linux’s adversarial lens. Her takeaways—leverage extant libs, preempt breaches, probe attacker tactics—empower swift fortifications, harmonizing security with agility.

[DotSecurity2017] Encryption vs. Inspection
The perennial pugilism pitting privacy’s palladium against oversight’s oracle unfolds in encrypted ethers, where safeguards clash with scrutiny’s siren song. Nick Sullivan, Cloudflare’s cryptography luminary, navigated this nautical narrative at dotSecurity 2017, tracing TLS’s tumultuous trajectory from 1990s’ munitions to 2017’s ubiquity—HTTPS’s hegemony, yet hobbled by proxies’ perfidy. A cryptographic cartographer charting Cloudflare’s cipher seas, Nick’s narrative—Netscape’s bifurcated builds to Clipper’s clandestine key—unveils encryption’s emancipation and inspection’s inexorable incursion.
Nick’s nautical nod to 1990s’ neuroses: crypto’s classification as contraband, 128-bit’s embargo—Netscape’s nativity, domestic duos versus export’s enfeebled editions. Clipper’s chimera: escrowed escrow, law enforcement’s latchkey—EFF’s excoriation eclipsing its eclipse. PGP’s philippic, Zimmermann’s zenith—crypto’s commoditization, DES’s desuetude via DES Cracker’s deluge. SSL’s sunrise: 1994’s blueprint, 1995’s beta—TLS’s transmutation, 1.0’s 1999 nativity, 1.2’s 2008 augmentation.
2017’s inflection: HTTPS’s half-century, inspection’s intensification—proxies’ prying, AV’s antivirus autopsies—MITM’s masquerade, certificates’ counterfeit. Nick nixed naivety: downgrade’s danger (POODLE’s peril, BEAST’s bite), padding’s ploy (Lucky Thirteen’s laceration). TLS 1.3’s talisman: 0-RTT’s alacrity, ephemeral’s eternity—forward secrecy fortified, inspection’s impasse. Chrome’s crusade: February’s field trial fracturing BlueCoat’s barricades—TLS 1.3’s triumph truncated by proxies’ protest.
Nick’s nexus: society’s schism—inspection’s imperative or encryption’s ethic? This dialectic: data’s dominion, decided in deployment’s dawn.
Munitions to Mainstream: Crypto’s Chronicle
Nick navigated 1990s’ neuroses: Clipper’s cloister, PGP’s proclamation—SSL’s sunrise, TLS’s transfiguration.
Inspection’s Incursion and TLS 1.3’s Triumph
Proxies’ perfidy, AV’s autopsy—downgrade’s dread, padding’s peril. 1.3’s aegis: 0-RTT’s rush, ephemeral’s edge—Chrome’s clash with BlueCoat.
