Generate RSA key pairs (2048/4096-bit) using the Web Crypto API. Export public and private keys as PEM strings. All client-side, no server uploads.
Generate SSH key pairs (ed25519/RSA) with copy-ready public and private parts. Set up server access in a minute — local Web Crypto, free, no signup.
Generate Postman collection JSON from endpoint descriptions. Create ready-to-import collections with method and path for each endpoint.
Converts JSON files to XML format — APIs, configuration files, and data exchange between web services to enterprise systems, SOAP APIs, document formatting, and legacy integration pipelines.
Generate PGP key pairs with OpenPGP.js — public for sharing, private stays local. Encrypt mail like it's 1991 but working — local crypto, unlimited saves.
RSA for broad compatibility, EC for compact modern keys, oct for shared secrets.
2048-bit RSA minimum mainstream; 256-bit EC roughly equivalent.
Key ID for lookup plus algorithm declaration — both embedded in the JWK.
No — generation uses browser cryptography locally, free with no signup.
