About Aya Corporation
The people and mission behind the tools
Abdul-Muqaddam
Core Architect behind Aya Corporation’s open-source developer tooling.
Welcome! I am a full-stack developer dedicated to building secure, lightweight, and local-first utilities that empower software engineers worldwide. In modern development, relying on untrusted web forms to format JSON, hash passwords, or generate test keys poses unnecessary data leakage risks.
That is why I built Aya Corporation, a set of developer tools you can open without an account. Encryption, encoding, formatting, and file tools run in the browser and do not upload what you paste. DNS lookup sends the hostname to a public resolver, and the DNS page says so. The site shows ads on ordinary pages. It does not show them on the embedded chess board.
My areas of interest include symmetric and asymmetric cryptography, stateless authentication (JWT), and local-first tools. The AES page on this site offers CBC, ECB, CTR, OFB, and CFB through CryptoJS. It does not offer GCM. The notes on each tool page match the script, including corrections when an older description was wrong.
Pages that only repeated another tool — a PNG-to-JPG address that loaded the same converter, a decimal-to-hex address that loaded the same base converter — now redirect to that tool. The chess screen embeds the board app and does not request ads. I would rather keep one honest page than a set of copied screens.
