Description
This command takes an optional CRL and one or more certificates and converts them into a PKCS#7
degenerate "certificates only" structure.
Examples
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
Name
openssl-crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates
Notes
The output file is a PKCS#7 signed data structure containing no signers and just certificates and an
optional CRL.
This command 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.
Options
-help
Print out a usage message.
-informDER|PEM
The input format of the CRL; the default is PEM. See openssl-format-options(1) for details.
-outformDER|PEM
The output format of the PKCS#7 object; the default is PEM. See openssl-format-options(1) for
details.
-infilename
This specifies the input filename to read a CRL from or standard input if this option is not
specified.
-outfilename
Specifies the output filename to write the PKCS#7 structure to or standard output by default.
-certfilefilename
Specifies a filename containing one or more certificates in PEM format. All certificates in the file
will be added to the PKCS#7 structure. This option can be used more than once to read certificates
from multiple files.
-nocrl
Normally a CRL is included in the output file. With this option no CRL is included in the output file
and a CRL is not read from the input file.
-providername-provider-pathpath-propquerypropq
See "Provider Options" in openssl(1), provider(7), and property(7).
