In PKI, which component verifies a user's identity before issuing a certificate?

Explanation:
Registration Authority verifies a user’s identity before a certificate is issued. It handles enrollment and identity validation—checking who the applicant is, their eligibility, and authority to obtain a certificate. Once identity is confirmed, the RA passes the validated request to the Certificate Authority, which then issues and signs the certificate that binds the user’s public key to that identity. The Repository stores issued certificates for clients to retrieve, while the Archive keeps historical records and revoked certificates. The RA’s role is essential because it provides the initial proof of identity required before any certificate is created.
