Let’s be honest: if your deployment workflow still involves an engineer manually downloading a .crt, pasting it into a web server configuration, and praying to the gods of uptime that they don’t forget to do it again in 90 days… you aren’t running a production environment. You are running a time bomb. The industry is undergoing a massive compression in certificate lifespans. We’ve moved from years to months, and now—driven by the momentum of Let’s Encrypt and pressure from browser vendors (Apple, Google) favoring high-frequency rotation—we are rapidly approaching an era where 90-day lifespans will feel like an eternity.

I’d try to elaborate on the options available from the active/passive investments PoV. Most Passive - VPS: Relatively safer, as you just have to identify the AMC/insurance copmany. Benefits: You can claim upto 20% tax rebate immediately in your tax returns (by claiming it from your employer if you are salaried individual) You have tax free (CGT, SST) compounding, meaning no tax on dividends/bonuses. Drawback: You have to pay extra fees incase of early (before duration of 25Y or age of 60Y) withdrawal.

This article explores the most feasible curve for Elliptic Curve Cryptography for the use case of Document Signing as per recommendations from the Guideline/standards formulating bodies. National Institute for Standards and Technology (NIST) As per NIST’s recommendations (see NIST SP 800-186) P-256, P-384, P-521 (for ECDSA) and Curve25519 and Curve448 (for EdDSA) are recommended as shown below: WebTrust & CAB Forum WebTrust or CA/B forum doesn’t have a dedicated requirements/standard for Document Signing use-case, however, the S/MIME requirements (both in WebTrust and CA/Browser forum) cover this use-case under multi-purpose certificates.
