NAME

6       crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates.
7

SYNOPSIS

9       openssl crl2pkcs7 [-inform PEM⎪DER] [-outform PEM⎪DER] [-in filename]
10       [-out filename] [-certfile filename] [-nocrl]
11

DESCRIPTION

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

COMMAND OPTIONS

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

EXAMPLES

48       Create a PKCS#7 structure from a certificate and CRL:
49
50        openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem
51
52       Creates a PKCS#7 structure in DER format with no CRL from several dif‐
53       ferent certificates:
54
55        openssl crl2pkcs7 -nocrl -certfile newcert.pem
56               -certfile demoCA/cacert.pem -outform DER -out p7.der
57

NOTES

59       The output file is a PKCS#7 signed data structure containing no signers
60       and just certificates and an optional CRL.
61
62       This utility can be used to send certificates and CAs to Netscape as
63       part of the certificate enrollment process. This involves sending the
64       DER encoded output as MIME type application/x-x509-user-cert.
65
66       The PEM encoded form with the header and footer lines removed can be
67       used to install user certificates and CAs in MSIE using the Xenroll
68       control.
