11[B<-inform PEM|DER>]
12[B<-outform PEM|DER>]

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

64=head1 EXAMPLES
65
66Create a PKCS#7 structure from a certificate and CRL:
67
68 openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
69
70Creates a PKCS#7 structure in DER format with no CRL from several
71different certificates:
72
73 openssl crl2pkcs7 -nocrl -certfile newcert.pem 
74	-certfile demoCA/cacert.pem -outform DER -out p7.der
75
76=head1 NOTES
77
78The output file is a PKCS#7 signed data structure containing no signers and
79just certificates and an optional CRL.
80
81This utility can be used to send certificates and CAs to Netscape as part of
82the certificate enrollment process. This involves sending the DER encoded output
83as MIME type application/x-x509-user-cert.
84
85The B<PEM> encoded form with the header and footer lines removed can be used to
86install user certificates and CAs in MSIE using the Xenroll control.
