crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates.
openssl crl2pkcs7 [-inform PEM|DER] [-outform PEM|DER] [-in filename] [-out filename] [-certfile filename] [-nocrl]
The crl2pkcs7 command takes an optional CRL and one or more certificates and converts them into a PKCS#7 degenerate ``certificates only'' structure.
Create a PKCS#7 structure from a certificate and CRL:
openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
Creates a PKCS#7 structure in DER format with no CRL from several different certificates:
openssl crl2pkcs7 -nocrl -certfile newcert.pem -certfile demoCA/cacert.pem -outform DER -out p7.der
The output file is a PKCS#7 signed data structure containing no signers and just certificates and an optional CRL.
This utility can be used to send certificates and CAs to Netscape as part of the certificate enrollment process. This involves sending the DER encoded output as MIME type application/x-x509-user-cert.
The PEM encoded form with the header and footer lines removed can be used to install user certificates and CAs in MSIE using the Xenroll control.
