Satellite Public Keys

Public keys for Cryptosat response authentication

Cryptosat attests to the authenticity of responses and broadcasts coming from its satellites by producing a digital signature over each response sent to the ground. The public keys listed here can be used to verify those responses. Public keys are over a 256-bit Koblitz curve (SECP256K1) and the signature scheme used is ECDSA over a SHA-256 hash of the data.
