PGP public keys used in the digital signature system of the FCR Operator.

These public keys allow users to verify the origin and integrity of emails received from the FCR Operator, notably to avoid a fraudulent attempt by a third-party to pass itself off as the FCR Operator (fraud technique commonly referred to as "phishing"). To perform these verifications, users need to install a PGP extension on their E-mail client and provide the appropriate public key. The digital signature system is based on the PGP protocol specified in RFC 4880 of the IETF.
