A CRL is generated and published periodically, often at a defined interval. A CRL can also be published immediately after a certificate has been revoked. A CRL is issued by a CRL issuer, which is typically the CA which also issued the corresponding certificates, but could alternatively be some other trusted authority.
A typical use of a PKCS #7 file would be to store certificates and/or certificate revocation lists (CRL). Here's an example of how to first download a certificate, then wrap it inside a PKCS #7 archive and then read from that archive:
A certificate revocation list (CRL) enumerates revoked certificates. They are cryptographically authenticated by the issuing CA. [29] CRLs have scalability issues, and rely on the client having enough network access to download them prior to checking a certificate's status. [9]
.crl – A Certificate Revocation List (CRL). Certificate Authorities produce these as a way to de-authorize certificates before expiration. PKCS#7 is a standard for signing or encrypting (officially called "enveloping") data. Since the certificate is needed to verify signed data, it is possible to include them in the SignedData structure.
Since an OCSP response contains less data than a typical certificate revocation list (CRL), it puts less burden on network and client resources. [9]Since an OCSP response has less data to parse, the client-side libraries that handle it can be less complex than those that handle CRLs.
Certificate authorities are also responsible for maintaining up-to-date revocation information about certificates they have issued, indicating whether certificates are still valid. They provide this information through Online Certificate Status Protocol (OCSP) and/or Certificate Revocation Lists (CRLs

The only increased risk of OCSP stapling is that the notification of revocation for a certificate may be delayed until the last-signed OCSP response expires. As a result, clients continue to have verifiable assurance from the certificate authority that the certificate is presently valid (or was quite recently), but no longer need to ...
