What is the secret and public key within an e-signature/certificate in Czech Republic?

The electronic signature is based on PKI technology (Public Key Infrastructure). It ensures the integrity of electronic documents (e.g. e-invoices) and the authenticity (identity) of the sender (invoice issuer). The signature consist of a certificate which has been assigned with a private and a public key. The private key is only known to the sender (invoice issuer) whereas the public key is submitted to the recipient (invoice recipient) of the signed document (e.g. e-invoice) to verify the electronic signature.
