Key Pair Generator API

Generate one new signing key pair (ECDSA, Ed25519 or RSA up to 4096 bits): PKCS#8 private key PEM, SPKI public key PEM, OpenSSH public key line and SHA-256 fingerprint. The key is created on PithLab's server and not stored; generate locally for production secrets.

Generate RSA, ECDSA and Ed25519 key pairs in your browser. Export the private key as PKCS#8 PEM, the public key as PEM and OpenSSH, with its SHA256 fingerprint.
