説明：This tool uses the browser Web Crypto API to generate standard RSA (RSASSA-PKCS1-v1_5) key pairs, wrapped in PGP-style ASCII Armor format. Key material is in standard SPKI (public) and PKCS#8 (private) formats, suitable for general encryption. For full OpenPGP format keys (with subkeys, user binding signatures, etc.), please use GPG or OpenPGP.js. All computation is done locally in the browser, keys are never uploaded.
