| 5 | openssl-crl2pkcs7, |
| 6 | crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates |
| 7 | |
| 8 | =head1 SYNOPSIS |
| 9 | |
| 10 | B<openssl> B<crl2pkcs7> |
| 11 | [B<-help>] |
| 12 | [B<-inform PEM|DER>] |
| 13 | [B<-outform PEM|DER>] |
| 14 | [B<-in filename>] |
| 15 | [B<-out filename>] |
| 16 | [B<-certfile filename>] |
| 17 | [B<-nocrl>] |
| 18 | |
| 19 | =head1 DESCRIPTION |
| 20 | |
| 21 | The B<crl2pkcs7> command takes an optional CRL and one or more |
| 22 | certificates and converts them into a PKCS#7 degenerate "certificates |
| 23 | only" structure. |
| 24 | |
| 25 | =head1 OPTIONS |
| 26 | |
| 27 | =over 4 |
| 28 | |
| 29 | =item B<-help> |
| 30 | |
| 31 | Print out a usage message. |
| 32 | |
| 33 | =item B<-inform DER|PEM> |
| 34 | |
| 35 | This specifies the CRL input format. B<DER> format is DER encoded CRL |
| 36 | structure.B<PEM> (the default) is a base64 encoded version of |
| 37 | the DER form with header and footer lines. The default format is PEM. |
| 38 | |
| 39 | =item B<-outform DER|PEM> |
| 40 | |
| 41 | This specifies the PKCS#7 structure output format. B<DER> format is DER |
| 42 | encoded PKCS#7 structure.B<PEM> (the default) is a base64 encoded version of |
| 43 | the DER form with header and footer lines. The default format is PEM. |
| 44 | |
| 45 | =item B<-in filename> |
| 46 | |
| 47 | This specifies the input filename to read a CRL from or standard input if this |
| 48 | option is not specified. |
| 49 | |
| 50 | =item B<-out filename> |
| 51 | |
| 52 | Specifies the output filename to write the PKCS#7 structure to or standard |
| 53 | output by default. |
| 54 | |
| 55 | =item B<-certfile filename> |
| 56 | |
| 57 | Specifies a filename containing one or more certificates in B<PEM> format. |
| 58 | All certificates in the file will be added to the PKCS#7 structure. This |
| 59 | option can be used more than once to read certificates from multiple |
| 60 | files. |
| 61 | |
| 62 | =item B<-nocrl> |
| 63 | |
| 64 | Normally a CRL is included in the output file. With this option no CRL is |
| 65 | included in the output file and a CRL is not read from the input file. |

| 69 | =head1 EXAMPLES |
| 70 | |
| 71 | Create a PKCS#7 structure from a certificate and CRL: |
| 72 | |
| 73 | openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem |
| 74 | |
| 75 | Creates a PKCS#7 structure in DER format with no CRL from several |
| 76 | different certificates: |
| 77 | |
| 78 | openssl crl2pkcs7 -nocrl -certfile newcert.pem |
| 79 | -certfile demoCA/cacert.pem -outform DER -out p7.der |
| 80 | |
| 81 | =head1 NOTES |
| 82 | |
| 83 | The output file is a PKCS#7 signed data structure containing no signers and |
| 84 | just certificates and an optional CRL. |
| 85 | |
| 86 | This utility can be used to send certificates and CAs to Netscape as part of |
| 87 | the certificate enrollment process. This involves sending the DER encoded output |
| 88 | as MIME type application/x-x509-user-cert. |
| 89 | |
| 90 | The B<PEM> encoded form with the header and footer lines removed can be used to |
| 91 | install user certificates and CAs in MSIE using the Xenroll control. |
