This 58option can be used more than once to read certificates from multiple 59files. 60 61=item B<-nocrl> 62 63Normally a CRL is included in the output file. With this option no CRL is 64included in the output file and a CRL is not read from the input file. 65 66{- $OpenSSL::safe::opt_provider_item -} 67 68=back 69 70=head1 EXAMPLES 71 72Create a PKCS#7 structure from a certificate and CRL: 73 74 openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem 75 76Creates a PKCS#7 structure in DER format with no CRL from several 77different certificates: 78 79 openssl crl2pkcs7 -nocrl -certfile newcert.pem 80 -certfile demoCA/cacert.pem -outform DER -out p7.der 81 82=head1 NOTES 83 84The output file is a PKCS#7 signed data structure containing no signers and 85just certificates and an optional CRL. 86 87This command can be used to send certificates and CAs to Netscape as part of 88the certificate enrollment process. This involves sending the DER encoded output 89as MIME type application/x-x509-user-cert. 90 91The B<PEM> encoded form with the header and footer lines removed can be used to 92install user certificates and CAs in MSIE using the Xenroll control. 93 94=head1 SEE ALSO 95 96L<openssl(1)>, 97L<openssl-pkcs7(1)> 98 99=head1 COPYRIGHT 100 101Copyright 2000-2021 The OpenSSL Project Authors.
