143 [\fB\-outform PEM|DER\fR]
145 [\fB\-in filename\fR]
146 [\fB\-out filename\fR]
147 [\fB\-nameopt option\fR]
153 [\fB\-CAfile file\fR]
156 .IX Header "DESCRIPTION"
157 The \fBcrl\fR command processes \s-1CRL\s0 files in \s-1DER\s0 or \s-1PEM\s0 format.
158 .SH "COMMAND OPTIONS"
159 .IX Header "COMMAND OPTIONS"
160 .IP "\fB\-inform DER|PEM\fR" 4
161 .IX Item "-inform DER|PEM"
162 This specifies the input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded \s-1CRL\s0
163 structure. \fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
164 the \s-1DER\s0 form with header and footer lines.
165 .IP "\fB\-outform DER|PEM\fR" 4
166 .IX Item "-outform DER|PEM"
167 This specifies the output format, the options have the same meaning as the
168 \&\fB\-inform\fR option.
169 .IP "\fB\-in filename\fR" 4
170 .IX Item "-in filename"
171 This specifies the input filename to read from or standard input if this
172 option is not specified.
173 .IP "\fB\-out filename\fR" 4
174 .IX Item "-out filename"
175 specifies the output filename to write to or standard output by
179 print out the \s-1CRL\s0 in text form.
180 .IP "\fB\-nameopt option\fR" 4
181 .IX Item "-nameopt option"
182 option which determines how the subject or issuer names are displayed. See
183 the description of \fB\-nameopt\fR in \fIx509\fR\|(1).
184 .IP "\fB\-noout\fR" 4
186 don't output the encoded version of the \s-1CRL.\s0
189 output a hash of the issuer name. This can be use to lookup CRLs in
190 a directory by issuer name.
191 .IP "\fB\-hash_old\fR" 4
193 outputs the \*(L"hash\*(R" of the \s-1CRL\s0 issuer name using the older algorithm
194 as used by OpenSSL versions before 1.0.0.
195 .IP "\fB\-issuer\fR" 4
197 output the issuer name.
198 .IP "\fB\-lastupdate\fR" 4
199 .IX Item "-lastupdate"
200 output the lastUpdate field.
201 .IP "\fB\-nextupdate\fR" 4
202 .IX Item "-nextupdate"
203 output the nextUpdate field.
204 .IP "\fB\-CAfile file\fR" 4
205 .IX Item "-CAfile file"
206 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
208 .IP "\fB\-CApath dir\fR" 4
209 .IX Item "-CApath dir"
210 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
211 \&\fBdir\fR. This directory must be a standard certificate directory: that
212 is a hash of each subject name (using \fBx509 \-hash\fR) should be linked
216 The \s-1PEM CRL\s0 format uses the header and footer lines:
219 \& \-\-\-\-\-BEGIN X509 CRL\-\-\-\-\-
220 \& \-\-\-\-\-END X509 CRL\-\-\-\-\-
223 .IX Header "EXAMPLES"
224 Convert a \s-1CRL\s0 file from \s-1PEM\s0 to \s-1DER:\s0
227 \& openssl crl \-in crl.pem \-outform DER \-out crl.der
230 Output the text form of a \s-1DER\s0 encoded certificate:
233 \& openssl crl \-in crl.der \-text \-noout
237 Ideally it should be possible to create a \s-1CRL\s0 using appropriate options
