Final answer:
CRL, CA, and OSCP are all responsible for issuing certificates.
Step-by-step explanation:
All of these are responsible for issuing certificates.
- CRL (Certificate Revocation List) is a list of digital certificates that have been revoked or invalidated.
- CA (Certificate Authority) is responsible for issuing and verifying the authenticity of digital certificates.
- OSCP (Online Certificate Status Protocol) is a protocol used to check the revocation status of digital certificates.
Each of these plays a crucial role in the certificate issuance process, ensuring the security and trustworthiness of digital certificates.
