35 =head1 DESCRIPTION
36
37 This command processes CRL files in DER or PEM format.
38
39 =head1 OPTIONS
40
41 =over 4
42
43 =item B<-help>
44
45 Print out a usage message.
46
47 =item B<-inform> B<DER>|B<PEM>
48
49 The CRL input format; unspecified by default.
50 See L<openssl-format-options(1)> for details.
51
52 =item B<-outform> B<DER>|B<PEM>
53
54 The CRL output format; the default is B<PEM>.
55 See L<openssl-format-options(1)> for details.
56
57 =item B<-key> I<filename>
58
59 The private key to be used to sign the CRL.
60
61 =item B<-keyform> B<DER>|B<PEM>|B<P12>
62
63 The format of the private key file; unspecified by default.
64 See L<openssl-format-options(1)> for details.
65
66 =item B<-in> I<filename>
67
68 This specifies the input filename to read from or standard input if this
69 option is not specified.
70
71 =item B<-out> I<filename>
72
73 Specifies the output filename to write to or standard output by
74 default.
75
76 =item B<-gendelta> I<filename>
77
78 Output a comparison of the main CRL and the one specified here.
79
80 =item B<-badsig>
81
82 Corrupt the signature before writing it; this can be useful
83 for testing.
84
85 =item B<-dateopt>
86
87 Specify the date output format. Values are: rfc_822 and iso_8601.
88 Defaults to rfc_822.
89
90 =item B<-text>
91
92 Print out the CRL in text form.
93
94 =item B<-verify>
95
96 Verify the signature in the CRL.
97
98 =item B<-noout>
99
100 Don't output the encoded version of the CRL.
101
102 =item B<-fingerprint>
103
104 Output the fingerprint of the CRL.
105
106 =item B<-crlnumber>
107
108 Output the number of the CRL.
109
110 =item B<-hash>
111
112 Output a hash of the issuer name. This can be use to lookup CRLs in
113 a directory by issuer name.
114
115 =item B<-hash_old>
116
117 Outputs the "hash" of the CRL issuer name using the older algorithm
118 as used by OpenSSL before version 1.0.0.
119
120 =item B<-issuer>
121
122 Output the issuer name.
123
124 =item B<-lastupdate>
125
126 Output the lastUpdate field.
127
128 =item B<-nextupdate>
129
130 Output the nextUpdate field.

140 =head1 EXAMPLES
141
142 Convert a CRL file from PEM to DER:
143
144 openssl crl -in crl.pem -outform DER -out crl.der
145
146 Output the text form of a DER encoded certificate:
147
148 openssl crl -in crl.der -text -noout
149
150 =head1 BUGS
151
152 Ideally it should be possible to create a CRL using appropriate options
153 and files too.
