| =head1 NAME |
| |
| crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates. |
| |
| =head1 SYNOPSIS |
| |
| B<openssl> B<crl2pkcs7> |
| [B<-inform PEM|DER>] |
| [B<-outform PEM|DER>] |
| [B<-in filename>] |
| [B<-out filename>] |
| [B<-certfile filename>] |
| [B<-nocrl>] |
| |
| =head1 DESCRIPTION |
| |
| The B<crl2pkcs7> command takes an optional CRL and one or more |
| certificates and converts them into a PKCS#7 degenerate "certificates |
| only" structure. |
| |
| =head1 COMMAND OPTIONS |
| |
| =over 4 |
| |
| =item B<-inform DER|PEM> |
| |
| This specifies the CRL input format. B<DER> format is DER encoded CRL |
| structure.B<PEM> (the default) is a base64 encoded version of |
| the DER form with header and footer lines. |
| |
| =item B<-outform DER|PEM> |
| |
| This specifies the PKCS#7 structure output format. B<DER> format is DER |
| encoded PKCS#7 structure.B<PEM> (the default) is a base64 encoded version of |
| the DER form with header and footer lines. |
| |
| =item B<-in filename> |
| |
| This specifies the input filename to read a CRL from or standard input if this |
| option is not specified. |
| |
| =item B<-out filename> |
| |
| specifies the output filename to write the PKCS#7 structure to or standard |
| output by default. |
| |
| =item B<-certfile filename> |
| |
| specifies a filename containing one or more certificates in B<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 form multiple |
| files. |
| |
| =item B<-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. |

| =head1 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 |
| |
| =head1 NOTES |
| |
| 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 B<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. |
