156 .SH "DESCRIPTION"
157 .IX Header "DESCRIPTION"
158 The \fBcrl2pkcs7\fR command takes an optional \s-1CRL\s0 and one or more
159 certificates and converts them into a PKCS#7 degenerate \*(L"certificates
160 only\*(R" structure.
161 .SH "COMMAND OPTIONS"
162 .IX Header "COMMAND OPTIONS"
163 .IP "\fB\-inform DER|PEM\fR" 4
164 .IX Item "-inform DER|PEM"
165 This specifies the \s-1CRL\s0 input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded \s-1CRL\s0
166 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
167 the \s-1DER\s0 form with header and footer lines.
168 .IP "\fB\-outform DER|PEM\fR" 4
169 .IX Item "-outform DER|PEM"
170 This specifies the PKCS#7 structure output format. \fB\s-1DER\s0\fR format is \s-1DER\s0
171 encoded PKCS#7 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
172 the \s-1DER\s0 form with header and footer lines.
173 .IP "\fB\-in filename\fR" 4
174 .IX Item "-in filename"
175 This specifies the input filename to read a \s-1CRL\s0 from or standard input if this
176 option is not specified.
177 .IP "\fB\-out filename\fR" 4
178 .IX Item "-out filename"
179 specifies the output filename to write the PKCS#7 structure to or standard
180 output by default.
181 .IP "\fB\-certfile filename\fR" 4
182 .IX Item "-certfile filename"
183 specifies a filename containing one or more certificates in \fB\s-1PEM\s0\fR format.
184 All certificates in the file will be added to the PKCS#7 structure. This
185 option can be used more than once to read certificates form multiple
186 files.
187 .IP "\fB\-nocrl\fR" 4
188 .IX Item "-nocrl"
189 normally a \s-1CRL\s0 is included in the output file. With this option no \s-1CRL\s0 is
190 included in the output file and a \s-1CRL\s0 is not read from the input file.
191 .SH "EXAMPLES"
192 .IX Header "EXAMPLES"

198 .PP
199 Creates a PKCS#7 structure in \s-1DER\s0 format with no \s-1CRL\s0 from several
200 different certificates:
201 .PP
202 .Vb 2
203 \& openssl crl2pkcs7 \-nocrl \-certfile newcert.pem
204 \& \-certfile demoCA/cacert.pem \-outform DER \-out p7.der
205 .Ve
206 .SH "NOTES"
207 .IX Header "NOTES"
208 The output file is a PKCS#7 signed data structure containing no signers and
209 just certificates and an optional \s-1CRL.\s0
210 .PP
211 This utility can be used to send certificates and CAs to Netscape as part of
212 the certificate enrollment process. This involves sending the \s-1DER\s0 encoded output
213 as \s-1MIME\s0 type application/x\-x509\-user\-cert.
214 .PP
215 The \fB\s-1PEM\s0\fR encoded form with the header and footer lines removed can be used to
216 install user certificates and CAs in \s-1MSIE\s0 using the Xenroll control.
