26=head1 DESCRIPTION
27
28The B<crl> command processes CRL files in DER or PEM format.
29
30=head1 OPTIONS
31
32=over 4
33
34=item B<-help>
35
36Print out a usage message.
37
38=item B<-inform DER|PEM>
39
40This specifies the input format. B<DER> format is DER encoded CRL
41structure. B<PEM> (the default) is a base64 encoded version of
42the DER form with header and footer lines.
43
44=item B<-outform DER|PEM>
45
46This specifies the output format, the options have the same meaning and default
47as the B<-inform> option.
48
49=item B<-in filename>
50
51This specifies the input filename to read from or standard input if this
52option is not specified.
53
54=item B<-out filename>
55
56Specifies the output filename to write to or standard output by
57default.
58
59=item B<-text>
60
61Print out the CRL in text form.
62
63=item B<-nameopt option>
64
65Option which determines how the subject or issuer names are displayed. See
66the description of B<-nameopt> in L<x509(1)>.
67
68=item B<-noout>
69
70Don't output the encoded version of the CRL.
71
72=item B<-hash>
73
74Output a hash of the issuer name. This can be use to lookup CRLs in
75a directory by issuer name.
76
77=item B<-hash_old>
78
79Outputs the "hash" of the CRL issuer name using the older algorithm
80as used by OpenSSL before version 1.0.0.
81
82=item B<-issuer>
83
84Output the issuer name.
85
86=item B<-lastupdate>
87
88Output the lastUpdate field.
89
90=item B<-nextupdate>
91
92Output the nextUpdate field.
93
94=item B<-CAfile file>
95
96Verify the signature on a CRL by looking up the issuing certificate in
97B<file>.
98
99=item B<-CApath dir>
100
101Verify the signature on a CRL by looking up the issuing certificate in
102B<dir>. This directory must be a standard certificate directory: that
103is a hash of each subject name (using B<x509 -hash>) should be linked
104to each certificate.
105
106=back
107
108=head1 NOTES
109
110The PEM CRL format uses the header and footer lines:
111
112 -----BEGIN X509 CRL-----
113 -----END X509 CRL-----
114
115=head1 EXAMPLES
116
117Convert a CRL file from PEM to DER:
118
119 openssl crl -in crl.pem -outform DER -out crl.der
120
121Output the text form of a DER encoded certificate:
122
123 openssl crl -in crl.der -inform DER -text -noout
124
125=head1 BUGS
126
127Ideally it should be possible to create a CRL using appropriate options
128and files too.
