RSA / EC Key Pair Generator
Generate RSA 2048/4096 and ECDSA P-256/P-384 key pairs, exported as PEM. Keys never leave the browser; download or copy from the page.
RSA / EC Key Pair Generator Use Cases
- Prototype JWT signing with local PEM files
- Generate throwaway keys for dev containers
- Teach asymmetric cryptography with exportable PEM
- Compare RSA vs elliptic curve key sizes
RSA / EC Key Pair Generator FAQ
What algorithms are used?
RSA keys use RSA-PSS with SHA-256; EC keys use ECDSA with NIST curves. Exported as PKIX SPKI and PKCS#8 PEM.
Are these production keys?
They are real keys from Web Crypto, but you must protect private material and follow your org policy for production use.
Can I use them for TLS?
You still need a certificate signed by a CA (or your own PKI). This tool only generates raw key pairs.
Where are private keys stored?
Only in your page until you leave or refresh. Save them securely if you need them later.
