Is a self-signed certificate inherently less secure than a CA-issued one?

The common advice — "never use self-signed, it's insecure" — conflates two distinct properties. A certificate does two jobs: it carries a public key for the key exchange, and it carries an identity assertion a relying party can verify. The cryptographic strength of a TLS (Transport Layer Security) session depends on the key and negotiated cipher suite, not on who signed the certificate. A self-signed RSA-3072 or P-256 certificate produces exactly the same handshake confidentiality as one from a public CA (Certificate Authority).

What self-signed certificates lack is third-party identity binding. The signature only attests "this key signed itself," so a relying party with no prior trust anchor cannot distinguish it from an attacker's. That is an authentication gap, not an encryption gap.

The distinction matters operationally. For internal service-to-service traffic where you control both endpoints and pin the certificate (or run a private CA), self-signed or private-CA certificates are entirely appropriate — see RFC 5280 §6 on path validation, which is what public trust automates.

— Encryption: identical
— Identity: absent unless pinned or pre-distributed

Further reading: RFC 5280, §6 (Certification Path Validation).
Bottom line: "insecure" is the wrong word. Self-signed certificates lack delegated identity verification, which only matters when the client has no out-of-band way to trust the key.

Автоматизация в арбитраже трафика: зачем и для кого?

В статье объясняется, какие сервисы автоматизации реально помогают в арбитраже трафика: автозалив, сценарии в антидетект-браузерах и low-code/no-code решения. Главный вывод — автоматизация экономит время и снижает рутину, но не заменяет команду, а ошибки в настройке могут повысить риск бана и лишних затрат.

1xBet перестал спонсировать эмоции

История о том, как казахстанцы зарегистрировали рекламный слоган 1xBet, а сам бренд оказался в юридической ловушке: после сделки с TonyBet права на товарный знак так и не выкупили. На фоне ареста активов Романа Семиохина и уголовного дела по азартным играм вывод простой: с 1xBet сейчас лучше не строить рекламные связки на рынке Казахстана.

За продажу аккаунтов в мессенджере теперь грозит статья

С 1 сентября 2026 года продажа аккаунтов соцсетей и мессенджеров в России стала уголовно и административно рискованной: штраф до 700 тысяч рублей, принудительные работы или лишение свободы до 2–3 лет. Если через аккаунт украдут деньги, продавца могут записать в соучастники мошенничества по ст. 159 УК РФ с риском до 10 лет.

Does moving from RSA-2048 to RSA-4096 meaningfully strengthen your TLS connections?

The advice to "always use 4096-bit RSA for better security" rests on a misreading of where the work happens. In a modern TLS 1.3 handshake the RSA key in your certificate is used only to sign the handshake transcript (authentication). The actual session secrets come from an ephemeral Elliptic Curve Diffie-Hellman (ECDHE) exchange, typically over Curve25519 or P-256. Your certificate key size does not determine forward secrecy or the symmetric key used to encrypt traffic.

NIST SP 800-57 Part 1 Rev. 5 rates RSA-2048 at roughly 112 bits of security, considered adequate well past 2030. RSA-4096 adds marginal headroom while imposing measurably higher CPU cost per signature — a non-trivial penalty on high-connection-rate servers.

The evidence-based upgrade path is not bigger RSA; it is switching the certificate to ECDSA (Elliptic Curve Digital Signature Algorithm) P-256, which delivers ~128-bit security with far smaller signatures and faster operations.

— RSA-2048: ~112-bit, fine to ~2030
— RSA-4096: diminishing return, higher cost
— ECDSA P-256: ~128-bit, faster

Further reading: NIST SP 800-57 Part 1 Rev. 5, Table 2.
Bottom line: For authentication strength per CPU cycle, prefer ECDSA over inflating RSA key length.

Google выпустил в релиз Gemini 3.8 flash

Google выпустил Gemini 3.8 Flash спустя две недели после 3.7: модель обещает сильный кодинг и быстрый отклик, а цена остаётся низкой — $0,75 за млн входящих токенов и $3,75 за млн исходящих. Вывод простой: пока Google демпингует, это выгодный вариант для тех, кому нужны дешёвые и быстрые нейросетевые запросы.

Does the padlock mean a site is trustworthy?

The persistent advice "look for the padlock to know a site is safe" was always a category error, and browsers have spent a decade unwinding it. A TLS (Transport Layer Security) padlock asserts exactly one thing: the connection to the server is encrypted and the server presented a certificate valid for that hostname. It says nothing about who operates the site or their intent.

The shift to free, automated issuance — Let's Encrypt issues for any hostname you control via the ACME (Automatic Certificate Management Environment) protocol, RFC 8555 — means phishing operators obtain Domain Validation (DV) certificates as trivially as anyone. Studies from the Anti-Phishing Working Group have for years reported that the substantial majority of phishing sites serve over HTTPS. The padlock is now table stakes, not a trust signal.

This is why Chrome removed the padlock icon in 2023, replacing it with a neutral "tune" glyph: usability research showed users misread it as a safety endorsement.

— DV proves control of the hostname, nothing more
— Organization/identity is not validated in DV
— Encryption ≠ legitimacy

Further reading: RFC 8555 (ACME); Chrome Security blog, "An update on the padlock icon" (2023).
Bottom line: The padlock means private, not trustworthy. Identity assurance requires looking at the certificate's validation level and the domain itself.

Do Extended Validation certificates improve trust signals or SEO?

Two myths cluster around EV (Extended Validation) certificates: that they boost search rankings, and that users notice them. Both fail under scrutiny. Google has stated that HTTPS is a lightweight ranking signal, but it draws no distinction between DV (Domain Validation), OV (Organization Validation), and EV — the crawler sees a valid certificate or it does not. There is no documented ranking differential by validation tier.

The user-facing premise collapsed first. EV's selling point was the green company-name bar in the address field. Both Chrome (2019) and Firefox removed that prominent EV indicator after their own usability studies — notably work by Thompson et al. presented around 2019 — found it did not change user behavior or improve phishing resistance. The identity now lives buried in the certificate details, where virtually no user looks.

EV still has narrow legitimate uses: a verified organization name in the certificate can matter for regulated B2B or legal attestation contexts.

— No ranking advantage over DV
— No prominent browser UI since ~2019
— Identity data still present, just unsurfaced

Further reading: Google Search Central, "HTTPS as a ranking signal"; Chromium EV UI removal rationale (2019).
Bottom line: Buy EV for organizational attestation if you need it — not for rankings or a UI badge that no longer exists.
