140 [\fB\-in filename\fR]

150 .IX Header "DESCRIPTION"
151 The \fBcrl\fR command processes \s-1CRL\s0 files in \s-1DER\s0 or \s-1PEM\s0 format.
152 .SH "COMMAND OPTIONS"
153 .IX Header "COMMAND OPTIONS"
154 .IP "\fB\-inform DER|PEM\fR" 4
155 .IX Item "-inform DER|PEM"
156 This specifies the input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded \s-1CRL\s0
157 structure. \fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
158 the \s-1DER\s0 form with header and footer lines.
159 .IP "\fB\-outform DER|PEM\fR" 4
160 .IX Item "-outform DER|PEM"
161 This specifies the output format, the options have the same meaning as the
162 \&\fB\-inform\fR option.
163 .IP "\fB\-in filename\fR" 4
164 .IX Item "-in filename"
165 This specifies the input filename to read from or standard input if this
166 option is not specified.
167 .IP "\fB\-out filename\fR" 4
168 .IX Item "-out filename"
169 specifies the output filename to write to or standard output by
173 print out the \s-1CRL\s0 in text form.
174 .IP "\fB\-noout\fR" 4
176 don't output the encoded version of the \s-1CRL\s0.
179 output a hash of the issuer name. This can be use to lookup CRLs in
180 a directory by issuer name.
181 .IP "\fB\-hash_old\fR" 4
183 outputs the \*(L"hash\*(R" of the \s-1CRL\s0 issuer name using the older algorithm
184 as used by OpenSSL versions before 1.0.0.
185 .IP "\fB\-issuer\fR" 4
187 output the issuer name.
188 .IP "\fB\-lastupdate\fR" 4
189 .IX Item "-lastupdate"
190 output the lastUpdate field.
191 .IP "\fB\-nextupdate\fR" 4
192 .IX Item "-nextupdate"
193 output the nextUpdate field.
194 .IP "\fB\-CAfile file\fR" 4
195 .IX Item "-CAfile file"
196 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
198 .IP "\fB\-CApath dir\fR" 4
199 .IX Item "-CApath dir"
200 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
201 \&\fBdir\fR. This directory must be a standard certificate directory: that
202 is a hash of each subject name (using \fBx509 \-hash\fR) should be linked
206 The \s-1PEM\s0 \s-1CRL\s0 format uses the header and footer lines:
209 \& \-\-\-\-\-BEGIN X509 CRL\-\-\-\-\-
210 \& \-\-\-\-\-END X509 CRL\-\-\-\-\-
213 .IX Header "EXAMPLES"
214 Convert a \s-1CRL\s0 file from \s-1PEM\s0 to \s-1DER:\s0
217 \& openssl crl \-in crl.pem \-outform DER \-out crl.der
220 Output the text form of a \s-1DER\s0 encoded certificate:
223 \& openssl crl \-in crl.der \-text \-noout
227 Ideally it should be possible to create a \s-1CRL\s0 using appropriate options
