This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

ECDSA Key Pair Generator performs key-pair generation for the supplied key or certificate data. The operation returns a public and private key pair in the selected format.

The operation returns a public and private key pair in the selected format. This result runs in the browser for this catalog category. Processing runs in the browser.

Key generation creates key material; it does not provide identity binding, storage protection, or certificate trust.

Instructions

  1. Provide text or data for this tool.
  2. Generate a disposable test pair with the selected algorithm settings. This applies to ECDSA Key Pair Generator.
  3. Keep the private key separate from the public key and output logs. This applies to ECDSA Key Pair Generator.
  4. Use the public key with a matching verifier or encryption operation. This applies to ECDSA Key Pair Generator.

Example

Input: Curve: P-256; output: PEM.

Settings: ECDSA Key Pair Generator: Choose the documented key type, curve, or RSA bit length. Choose PEM, JWK, or ASCII-armored output when exposed. Use a public test generation only; never reuse generated private keys in examples.

Result: The operation returns a public and private key pair in the selected format.

Limits

  • ECDSA Key Pair Generator: The tool does not store, escrow, or rotate generated private keys.
  • ECDSA Key Pair Generator: Key generation does not prove that a key belongs to a person or service.
  • ECDSA Key Pair Generator: Production key protection needs an approved key-management process.
