  18 =head1 DESCRIPTION
  19
  20 This command takes an optional CRL and one or more
  21 certificates and converts them into a PKCS#7 degenerate "certificates
  22 only" structure.

  24 =head1 OPTIONS
  25
  26 =over 4
  27
  28 =item B<-help>
  29
  30 Print out a usage message.
  31
  32 =item B<-inform> B<DER>|B<PEM>
  33
  34 The input format of the CRL; the default is B<PEM>.
  35 See L<openssl(1)/Format Options> for details.
  36
  37 =item B<-outform> B<DER>|B<PEM>
  38
  39 The output format of the PKCS#7 object; the default is B<PEM>.
  40 See L<openssl(1)/Format Options> for details.
  41
  42 =item B<-in> I<filename>
  43
  44 This specifies the input filename to read a CRL from or standard input if this
  45 option is not specified.
  46
  47 =item B<-out> I<filename>
  48
  49 Specifies the output filename to write the PKCS#7 structure to or standard
  50 output by default.
  51
  52 =item B<-certfile> I<filename>
  53
  54 Specifies a filename containing one or more certificates in B<PEM> format.
  55 All certificates in the file will be added to the PKCS#7 structure. This
  56 option can be used more than once to read certificates form multiple
  57 files.
  58
  59 =item B<-nocrl>
  60
  61 Normally a CRL is included in the output file. With this option no CRL is
  62 included in the output file and a CRL is not read from the input file.

  66 =head1 EXAMPLES
  67
  68 Create a PKCS#7 structure from a certificate and CRL:
  69
  70  openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
  71
  72 Creates a PKCS#7 structure in DER format with no CRL from several
  73 different certificates:
  74
  75  openssl crl2pkcs7 -nocrl -certfile newcert.pem
  76         -certfile demoCA/cacert.pem -outform DER -out p7.der
  77
  78 =head1 NOTES
  79
  80 The output file is a PKCS#7 signed data structure containing no signers and
  81 just certificates and an optional CRL.
  82
  83 This command can be used to send certificates and CAs to Netscape as part of
  84 the certificate enrollment process. This involves sending the DER encoded output
  85 as MIME type application/x-x509-user-cert.
  86
  87 The B<PEM> encoded form with the header and footer lines removed can be used to
  88 install user certificates and CAs in MSIE using the Xenroll control.
