DESCRIPTION
The `crl2pkcs7` command is a utility for converting Certificate Revocation Lists (CRLs) into the PKCS#7 (Cryptographic Message Syntax) format. PKCS#7 is a standard used for signing and encrypting data, including digital certificates and CRLs. By converting a CRL to PKCS#7, it can be more easily embedded within other applications or processed by systems that expect data in this format. The command typically takes a CRL file as input and outputs the PKCS#7 representation to either standard output or a specified file.
It is useful for scenarios where you need to incorporate CRL information into a secure message or data structure that adheres to PKCS#7 standards. This is often encountered in security protocols and applications that rely on digital signatures and certificate validation. OpenSSL is often used alongside this command, since crl2pkcs7 may be a specific implementation dependent on OpenSSL or similar cryptographic libraries. For instance, OpenSSL commands can be used to generate CRLs, which are then processed with `crl2pkcs7`.
CAVEATS
The exact behavior and availability of `crl2pkcs7` might depend on the specific cryptographic library or toolkit installed on your system. Check the documentation for your OpenSSL (or similar) installation for the most accurate details.
EXAMPLE USAGE
Convert a CRL file named `mycrl.pem` to a PKCS#7 file named `mycrl.p7`: crl2pkcs7 -in mycrl.pem -out mycrl.p7
Include a certificate file named `mycert.pem`: crl2pkcs7 -in mycrl.pem -certfile mycert.pem -out mycrl.p7
