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