141 .TH CRL 1 "0.9.7a" "2003-02-19" "OpenSSL"
144 crl \- \s-1CRL\s0 utility
146 .IX Header "SYNOPSIS"
147 \&\fBopenssl\fR \fBcrl\fR
148 [\fB\-inform PEM|DER\fR]
149 [\fB\-outform PEM|DER\fR]
151 [\fB\-in filename\fR]
152 [\fB\-out filename\fR]
158 [\fB\-CAfile file\fR]
161 .IX Header "DESCRIPTION"
162 The \fBcrl\fR command processes \s-1CRL\s0 files in \s-1DER\s0 or \s-1PEM\s0 format.
163 .SH "COMMAND OPTIONS"
164 .IX Header "COMMAND OPTIONS"
165 .Ip "\fB\-inform DER|PEM\fR" 4
166 .IX Item "-inform DER|PEM"
167 This specifies the input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded \s-1CRL\s0
168 structure. \fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
169 the \s-1DER\s0 form with header and footer lines.
170 .Ip "\fB\-outform DER|PEM\fR" 4
171 .IX Item "-outform DER|PEM"
172 This specifies the output format, the options have the same meaning as the
173 \&\fB\-inform\fR option.
174 .Ip "\fB\-in filename\fR" 4
175 .IX Item "-in filename"
176 This specifies the input filename to read from or standard input if this
177 option is not specified.
178 .Ip "\fB\-out filename\fR" 4
179 .IX Item "-out filename"
180 specifies the output filename to write to or standard output by
184 print out the \s-1CRL\s0 in text form.
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\-issuer\fR" 4
194 output the issuer name.
195 .Ip "\fB\-lastupdate\fR" 4
196 .IX Item "-lastupdate"
197 output the lastUpdate field.
198 .Ip "\fB\-nextupdate\fR" 4
199 .IX Item "-nextupdate"
200 output the nextUpdate field.
201 .Ip "\fB\-CAfile file\fR" 4
202 .IX Item "-CAfile file"
203 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
205 .Ip "\fB\-CApath dir\fR" 4
206 .IX Item "-CApath dir"
207 verify the signature on a \s-1CRL\s0 by looking up the issuing certificate in
208 \&\fBdir\fR. This directory must be a standard certificate directory: that
209 is a hash of each subject name (using \fBx509 \-hash\fR) should be linked
213 The \s-1PEM\s0 \s-1CRL\s0 format uses the header and footer lines:
216 \& -----BEGIN X509 CRL-----
217 \& -----END X509 CRL-----
220 .IX Header "EXAMPLES"
221 Convert a \s-1CRL\s0 file from \s-1PEM\s0 to \s-1DER:\s0
224 \& openssl crl -in crl.pem -outform DER -out crl.der
226 Output the text form of a \s-1DER\s0 encoded certificate:
229 \& openssl crl -in crl.der -text -noout
233 Ideally it should be possible to create a \s-1CRL\s0 using appropriate options
