Build certificates for any purpose—whether it's securing domains, IPs, or creating your own mini certificate authority. Supports CA flags, path length constraints, SANs, and more. Perfect for testing, development, or spinning up a custom trust chain.
generate certificate chain
Easily create and organize X.509 certificate chains from root to leaf. Generate intermediate certificates, link, and export complete chains for use in TLS, code signing, or custom PKI setups.
certificate info
A lightweight utility that parses and displays key details from X.509 certificates. It extracts and presents fields such as subject, issuer, validity period, public key info, signature algorithm, and extensions like Subject Key Identifier and Authority Key Identifier. Ideal for developers, sysadmins, or security analysts who need to quickly inspect certificate metadata for debugging, validation, or compliance purposes.
verify certificate
Verify X.509 certificates instantly with our online utility. Check the full chain of trust, validate issuers, and ensure your SSL/TLS certificates are secure and compliant — fast, reliable, and browser‑based.
generate key pair
"Generate secure RSA key pairs online with ease. Create public and private keys instantly in your browser for encryption, authentication, or digital signatures — fast, reliable, and hassle‑free.
extract public key
Extract public keys from X.509 certificates online. Quickly parse certificates to reveal the associated RSA or ECC public key — simple, secure, and browser‑based.
sign / verify file
Sign and verify data using X.509 certificates online. Ensure authenticity and integrity with secure digital signatures backed by trusted certificate chains — fast, reliable, and browser‑based.
encrypt file / text

blog

Welcome to a space dedicated entirely to code. This blog strips away the noise and focuses on the craft itself — from simple snippets to deeper explorations of programming concepts. Whether it’s experimenting with raw Node.js, dissecting language quirks, or building utilities from scratch, the goal here is to celebrate the elegance and power of code in its purest form.

code/dev

Dont expect explanations, tutorials — just raw, readable snippets. Think of it as a scratchpad, a stream, a place to muse through ideas in motion. Every listing is runnable and editable, so you can poke around, learn something new, or take it somewhere else.

Some entries might evolve into full blog posts. Others might get forked, remixed, or echoed by readers. It’s a living archive of curiosity — a comic book for coders, if you’ve got five minutes and a keyboard.
