About this tool

Generate RSA (2048, 3072 or 4096 bit), ECDSA (P-256, P-384, P-521) or Ed25519 key pairs with WebCrypto and export them as PKCS#8 and SPKI PEM, as JWK and as an OpenSSH public key line with your comment, ready for authorized_keys. Ed25519 needs a browser that supports it in WebCrypto.

The keys are created on your device and never leave it.
