NAME

6       openssl-crl2pkcs7, crl2pkcs7 - Create a PKCS#7 structure from a CRL and
7       certificates
8

SYNOPSIS

10       openssl crl2pkcs7 [-help] [-inform PEM|DER] [-outform PEM|DER] [-in
11       filename] [-out filename] [-certfile filename] [-nocrl]
12

DESCRIPTION

14       The crl2pkcs7 command takes an optional CRL and one or more
15       certificates and converts them into a PKCS#7 degenerate "certificates
16       only" structure.
17

OPTIONS

19       -help
20           Print out a usage message.
21
22       -inform DER|PEM
23           This specifies the CRL input format. DER format is DER encoded CRL
24           structure.PEM (the default) is a base64 encoded version of the DER
25           form with header and footer lines. The default format is PEM.
26
27       -outform DER|PEM
28           This specifies the PKCS#7 structure output format. DER format is
29           DER encoded PKCS#7 structure.PEM (the default) is a base64 encoded
30           version of the DER form with header and footer lines. The default
31           format is PEM.
32
33       -in filename
34           This specifies the input filename to read a CRL from or standard
35           input if this option is not specified.
36
37       -out filename
38           Specifies the output filename to write the PKCS#7 structure to or
39           standard output by default.
40
41       -certfile filename
42           Specifies a filename containing one or more certificates in PEM
43           format.  All certificates in the file will be added to the PKCS#7
44           structure. This option can be used more than once to read
45           certificates form multiple files.
46
47       -nocrl
48           Normally a CRL is included in the output file. With this option no
49           CRL is included in the output file and a CRL is not read from the
50           input file.
51

EXAMPLES

53       Create a PKCS#7 structure from a certificate and CRL:
54
55        openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
56
57       Creates a PKCS#7 structure in DER format with no CRL from several
58       different certificates:
59
60        openssl crl2pkcs7 -nocrl -certfile newcert.pem
61               -certfile demoCA/cacert.pem -outform DER -out p7.der
62

NOTES

64       The output file is a PKCS#7 signed data structure containing no signers
65       and just certificates and an optional CRL.
66
67       This utility can be used to send certificates and CAs to Netscape as
68       part of the certificate enrollment process. This involves sending the
69       DER encoded output as MIME type application/x-x509-user-cert.
70
71       The PEM encoded form with the header and footer lines removed can be
72       used to install user certificates and CAs in MSIE using the Xenroll
73       control.
