What does financial ca mean?

CA(CertificationAuthority) is the international name of a certification body, which refers to the institution that issues, manages and cancels digital certificates for digital certificate applicants. The role of CA is to check the legitimacy of the certificate holder's identity and issue certificates (sign certificates) to prevent certificates from being forged or tampered with. ?

The certificate binds the public key data and the identity information of the corresponding private key owner, and has the digital signature of CA. The certificate also contains the name of the CA (LOIS CA in the figure) so that the relying party can find the public key of the CA and verify the digital signature on the certificate.
